GENERAL CONSIDERATION What is Investigation? To carry out a detailed examination or inquiry, usually in official manner, to discover something or somebody. To search into, examine in detail, or inquire into systematically. A careful search or examination of something, or a systematic inquiry. In criminological sense, it is a patient, step-by-step (systematic) and careful (thorough) examination of something or someone. GENERAL CONSIDERATION Origin of the word investigation The term comes from the Latin word “VESTIGARE” (in some book INVESTIGARE) which means to tract or trace or probe. It also came from the Latin term INVESTIGARE and INVESTIGAT, which means “to inquire or to discover” during the 5th century. As to its etymology: it came from the Latin word “VESTIGIUM”, meaning“ footprints.” “to look into for traces or footprints” GENERAL CONSIDERATION What is Criminal Investigation? Benette: It seeks all facts associated with a crime to determine the truth: what happened and who is responsible of a criminal incident. Agas and Cael: It is the collection and analysis of facts about persons, things and places, subject of a crime to identify the guilty party, locate the whereabouts of the guilty party, and provide admissible evidences to establish the guilt of parties involved in a crime. AS AN ART: It is governed by intuition, felicity/inspiration and to minor extent by chance. (a natural ability or power that makes it possible to know something without any proof.) ***According to Hans Gross, It involves 95% perspiration, 3% inspiration and 2% luck. ? AS A SCIENCE: it involves the application of knowledge of forensic sciences in the process of identifying, locating, collecting, processing, and/or evaluating physical evidences. GENERAL CONSIDERATION Goals of Criminal Investigation 1. To determine whether a crime has been committed; 2. To legally obtain information or evidence; 3. To identify persons involved; 4. To arrest suspects; 5. To recover stolen properties; and 6. To present the best possible case to the prosecutor. GENERAL CONSIDERATION Kinds of Criminal Investigation 1. Investigation while the suspect is under arrest and detention; and 2. Investigation while the suspect is “at large”. ***at large- not being a wanted person before the eyes of the law, and therefore cannot be lawfully arrested without a warrant. ***fugitive from justice- an escapee from detention or an escaped prisoner while serving sentence by virtue of a final judgment rendered by a court of competent jurisdiction that can be legally arrested without the necessity of a warrant of arrest based from par. c, Sec 5, Rule 113, Rules of Court. THE THREE PHASES OF INVESTIGATION Preliminary Investigation P – roceed to scene promptly and safely R – ender assistance to injured E – ffect arrest of the criminals L – ocate and identify witnesses I – nterview complainant and witnesses M – aintain integrity of crime scene and protect evidence I – nterrogate suspects as necessary N – ote conditions, events and remarks A – rrange for evidence collection or collect it yourself R – eport the entire incident fully and accurately Y – ield responsibility to follow-up investigator or superior officer In – Depth Investigation It follows up initial lead steaming from the preliminary investigation In – depth investigation is the reexamining of the preliminary investigation, revisiting the crime scene, further process the crime scene, interviewing of existing and new victims and witnesses, processing of documents, gathering of facts and evidence, and application of criminalistics. Concluding Investigation The direct outgrowth of the previous two stages. The investigating officer works closely with the prosecuting attorney. Criminal case should be prepared for trial in different manner. Key Principles in Criminal Investigation 4. It refers to the process of determining the probative value of the evidence. a. b. Recognition Evaluation ? c. Collection d. Preservation e. Presentation FUNDAMENTALS OF CRIMINAL INVESTIGATION GENERAL CONSIDERATION Key Principles in Criminal Investigation 1.Recognition/ identification - the efforts of identifying data, including physical things that may provide relevant information regarding the criminal case being investigated. 2.Collection - the act of gathering those identified data or facts, or physical things that are significant to the case under investigation. Collection maybe done by scraping the bloodstains found at the crime scene, interviewing the neighbor who saw the burglary, or examination of drug dealer’s bankbook. FUNDAMENTALS OF CRIMINAL INVESTIGATION GENERAL CONSIDERATION Key Principles in Criminal Investigation 3. Preservation - almost simultaneously performed during the collection stage. It includes act of keeping the collected evidences in their true and original form, preventing contamination or destruction of its substantive value. 4. Presentation - primarily manifested inside the courtroom. Investigator help the prosecutor to be able to present facts in a very simple and convenient manner in order to convince the court about the validity and truthfulness of the evidences they are trying to prove or establish. Deductive and Inductive Reasoning 1.A deductive reasoning is one you decide is the answer of the case, and which you then attempt to prove with a collection of facts. To put it in another way, you “jump at a conclusion” and then undertake to show that your guess was right. 2.Inductive reasoning collects all the facts available first and allows them to determine the judgment. After you carefully examine all the details of a case you will be compelled to come to some conclusion regarding them.

Then the suspect is questioned about his activity prior, during and after the commission of the crime. This is repeated many times, to include the investigator focusing his questions about the knowledge of the suspect of the crime. 5. Mutt and Jeff (Sweet and Sour/Angel and Devil Method) – There are two investigator. The first set of investigators must appear to be rough, mean and dangerous while the second set is sympathetic and understanding. 6. Removing the Ethnic or Cultural Barrier - It is the Filipino’s way of life that we put our trust and confidence to those who belong to our clan or tribe. The interrogation must be in the language or dialect of the suspect so that we could get his full confidence. This is removing the language barrier. 7. Searching for the Soft Spot - In every man’s heart, there is always that softest spot. That spots maybe the youngest child, the wife, the mother, and the brother who acted as his father, the grandparents or the best friend. Once discovered, there must be a face-to-face meeting with that special person and that heart of steel will melt to pieces. TECHNIQUES IN INTERROGATION 8. Rationalization - It is the use of reasons, which is acceptable to the subject that led to the commission of the crime. 9. Projection - It is the process of putting the blame to other persons, not alone to the suspect. 10.Minimization - It is the act of minimizing the culpability of the suspect. The investigator convinces the suspect that a confession will reduce the offense and the penalty. SIGNS OF DECEPTION 1. Excessive Sweating - indicates tension, anxiety, shock or fear. 2. Change of Facial Color - A pale face is a reliable indicator of guilt or deception. 3. Dry Mouth 4. Excessive Breathing 5. Increase of Pulse Beat 6. Avoidance of Direct Eye Contact INTERROGATION ROOM The room chosen for the interrogation should provide freedom from distractions. It should be designed for simplicity with a view to enhancing the concentration of both of the interrogation and the subject on the matter under interrogation. Privacy. Interruption dispel of concentration that may have been carefully cultivated by the investigator, hence, the following are desirable: 1. Restricted Entrance - Investigator single door is preferable. Several doors suggest Suspect possible interruption and destroy the sense of focused attention. 2. absence of window or view. 3. sound proofing. 4. telephone without bell Simplicity. Distracting influence should be kept minimum. The suspect may strive to avoid the investigator’s concentration by focusing Lights his attention on some object in the room which Wall clock suggest a different train of Doors thought. Telephone without bell 1. Medium Sized Room. 2. Bare Walls. Pictures and Video charts are distracting. cam Two way3. No Glaring Lights mirror 4. Minimum Furniture.

This device appears to be a plain mirror on one side but permits a person on Recorder the other side to see through without being observed. Seating Arrangement. The Subject and the investigator should be seated with no large furniture between them. 1. Chair. Armless, straight back chair for the suspect. Armless chair 2. Table or Desk. The investigator requires a flat surface on which to place papers and articles of Su evidence. s to t pect 3. Suspects.

Su sp ect Listeni Recorder ng Device Investigator Whole view of the Interrogation Room CONFESSION AND ADMISSION CONFESSION: The declaration of an accused acknowledging his guilt of the offense charged, or of any offense necessarily included therein, may be given in evidence against him. (Sec. 33, Rule 130, Rules of Court) ADMISSION: A statement, oral or written, made by a party, or by someone for whom he is responsible as to the existence of a relevant fact.

ARREST, SEARCH, SEIZURE AND RAID ARREST The term “arrest” came from the Latin word “arrestare” which means “cause to stop” and “restare” which means “stay behind”. This term was used as early as during the 14th century. It is the taking of a person into custody in order that he may be bound to answer for the commission of an offense (Sec. 1, Rule 113, Rules of Court). How Arrest is made? It is made by an actual restraint of a person to be arrested or by his submission to the custody of the person making the arrest (Sec. 2, Rule 113, Rules of Court). Execution of Warrant The head of office to whom the warrant of arrest was delivered for execution shall cause the warrant to be executed within 10 days from its receipt. Within 10 days after the expiration of the period, the officer to whom it was assigned for execution shall make a report to the judge who issued the warrant. In case of failure to execute the warrant, he shall state the reasons therefor (Sec. 4, Rule 113, Rules of Court). Note: A warrant of arrest has NO expiry date. It remains valid until arrest is effected or warrant is lifted. Two Modes of Arrest 1. Arrest by virtue of a warrant; ***W arrant of Arrest is an order in w riting issued in the name of the People of the Philippines signed by a judge directed to a peace officer, commanding him to arrest the person designated and take him into custody of the law in order that he may be bound to answ er for the commission of an offense. 2. Arrest without a warrant under exceptional circumstances as may be provide by the statute (Sec. 5, Rule 113, Rules of Court). Two Modes of Arrest Requisites: 1.It must be issued upon probable cause which may be determined personally by a judge after examination under oath or affirmation of the complainant and the witnesses he may produce; What is Probable 2.The warrant must Cause? Probable particularly cause describe the refers persontoto the facts and circumstances which be seized. could lead a reasonable, discreet and prudent man to believe that the property subject of an offense is in the place sought to be searched. A. Richard Doe/John Doe Warrant A warrant containing no specific person to be arrested but only descriptions based from the testimonies of the victim/s or the witnesses. It contains the physical description of the accused as well as other factors to be considered for the identification of the accused. B. General Warrant Warrant with no specific subject. Not allowed. C. Scattered Shot Warrant A form of general warrant having D. Alias Warrant to or more subjects. Not allowed. Alias Warrant refers to the warrant of arrest issued by a judge to the peace officer after returning the original warrant of arrest after the lapse of the 10-day validity period. THE WARRANTLESS ARREST 1. When, in his presence, the person to be arrested has committed, is actually committing, or is attempting to commit an offense (in flagrante delicto arrest). 2. When an offense has in fact just been committed and he has probable cause to believe based on personal knowledge of facts or circumstances that the person to be arrested has committed it (doctrine of hot pursuit). THE WARRANTLESS ARREST 3. When the person to be arrested is an escapee. 4. When an accused who was released on bail attempts to depart from the Philippines without prior permission of the court where the case is pending (Sec. 23, Rule 114, Rules of Court). 5. For the purpose of surrendering the accused, the bondsmen may arrest him or. Upon written authority endorsed on a certified copy of the undertaking, cause him to be arrested by a police officer or any other person of suitable age and discretion. (Par. 1 Sec. 23 Rule 114, Rules of Court) THE WARRANTLESS ARREST 6. If a person lawfully arrested escapes or is recued, any person may immediately pursue or take him without a warrant at any time and in any place within the Philippines. (After escape or rescue doctrine) 7. Violent insanity (Art 124, RPC). 8. Ailment requiring compulsory confinement in a hospital (Art 124, RPC). If he was arrested without a warrant for the commission of a crime, he can be detained for: 1. 12 hours if the crime is punishable by Arresto Menor (prison term from 1 to 30 days), public censure, fine below PHP 200. 2. 24 hours if the crime is punishable by Prision Correccional (prison term from 6 months and 1 day to 6 years), Arresto Mayor (prison term from1month and 1 day to 6 months), Suspension, Destierro, Fine from PHP 200 to PHP 6,000. 3. 36 hours if the crime is punishable by Reclusion Perpetua (Literally life imprisonment. But pardon is provided by law after 30 years service) Reclusion Temporal (prison term from 12 years and 1 day to 20 years), Perpetual or Temporary Absolute Disqualification, Perpetual or Temporary Special Disqualification, Prision Mayor (prison term from 6 years and 1 day to 12 years), Fine exceeding PHP 6,000 (Article 124, Revised Penal Code II). SEARCH AND SEIZURE The word “search” was derived from the Anglo- Norman word “searcher,” Old French cerchier which means “to explore,” and Latin word “circare" which means “go around in circles”. Search is the act of examining persons, documents, papers and effects. An order in writing issued in the name of the People of the Philippines, signed by the judge and directed to a peace officer commanding him to search for personal property and bring it before the court (Sec. 1, Rule 1126, Rules of Court). SEARCH AND SEIZURE (Sec 2, Art III, 1987 Constitution) The word “search” was derived from the Anglo-Norman word “searcher,” Old French cerchier which means “to explore,” and Latin word “circare" which means “go around in circles”. Search is the act of examining persons, documents, papers and effects. An order in writing issued in the name of the People of the Philippines, signed by the judge and directed to a peace officer commanding him to search for personal property and bring it before the court (Sec. 1, Rule 1126, Rules of Court). Seizure is the taking into custody of property found by searching. REQUISITE BEFORE A SEARCH WARRANT IS ISSUED It must be issued upon probable cause. It must be determined personally by judge after examining the complainant and the witness he may produces. It must particularly describe the thing to be seized. Who should witness a search? No search of a house, room, or any other premise shall be made except in the presence of any of the following: 1. The legal occupant thereof; 2. Any member of his family; 3. In the absence of the latter, two witnesses of sufficient age and discretion residing in the same locality according to sec 8, Rule 126, Revised Rules of Court (Reyes, 2001). What are the personal properties to be seized? 1. Subject of the offense; 2. Stolen or embezzled and other proceeds, or fruits of the offense; or 3. Used or intended to be used as the means of committing an offense (Sec. 3, Rule 126, Revised Rules of Court). Instances of Warrantless Searches 1.

It is a small- scale attack of a limited territory. A raid must be legal, having its basis in lawful process and conducted in a legal manner through search warrant or warrant of arrest. Raid may be in pursuit of a person reasonably believed to be guilty of a felony when it is known that the felony has just been committed. PURPOSE OF A RAID 1. To effect apprehension; 2. To obtain evidence of illegal activity by surprising the offenders in flagrante delicto; or 3. To recover stolen property Composition of a Raid Team 1. Raid commander; 5. In charge of rendering 2. Assistant raid inoperative to the commander; subject’s vehicle, if 3. Covering or surrounding any; party; 6. Recorder who should 4. Going-in detail or keep log of the raid, entering party; gather evidence, 5. In charge of raiding make inventories and vehicle; testify in court, and 7. Photographer Don’ts in a Raid 1. Don’t take unnecessary chances; 2. Don’t underestimate the ability or courage of the subject (s); 3. Don’t raid when not properly prepared; 4. Don’t endanger the lives of bystander; 5. Don’t use raiders that are not well-acquainted with each other; 6. Don’t forget gas mask when employing tear gas; 7. Don’t make unnecessary rough on the subject(s); 8. Don’t shoot to kill unless very imperative; 9. Don’t touch the evidence unless seen by witnesses, or by the owner or occupant of the place SHOOT-TO-KILL ORDER 1. Would it be legal for the President of the Republic of the Philippines, or, the Secretary of Justice, or the Secretary of the Interior and Local Government, or any other superior public officers to declare or issue a “shoot to kill order” against suspected criminal offenders or accused persons who are at large and charged of heinous crimes, or against notorious criminals, or fugitives of justice who are known to be heavily armed and dangerous? SHOOT-TO-KILL ORDER ANSWER: NO. A “shoot to kill order” is not only a palpable, flagrant, deliberate and intentional violation of the constitutional and procedural due process and violation of human rights, but more importantly, is inherently illegal per se. There is no existing law or jurisprudential authority in the Philippines that legally allow such kind of order. SHOOT-TO-KILL ORDER 1. Why a “shoot to kill order” is inherently illegal per se? Answer: A “shoot to kill order” is NOT SYNONYMOUS to a cautionary warning to law enforcers to be extra-careful in pursuing the wanted criminals for being armed and dangerous. It is a basic rule of law that in case of imminent danger to life and limb, the law enforcers are legally bound, in the lawful performance of their duty, to use reasonable force to prevent and repel it. Obviously, a “shoot to kill order” is an IMPLIED INSINUATION for law enforcers to disregard the rule of law and the “rule of engagement” if only to accomplish the ultimate purpose of subduing the illegal activities of criminal elements. No matter how noble and patriotic the purpose may be, the “MEANS DOES NOT JUSTIFY THE END.” Collecting, Marking, Tagging, and Preserving Evidence Collecting Evidence Collection of liquid blood: Use clean, disposable pipette or eyedropper for each sample collected. Place the sample in a container, avoiding air space because air will cause the blood to dry. If the amount of blood is minimal, collection may best be made by placing the sample in a normal saline solution (1 tablespoon salt in 1 quart of distilled water. Refrigerate sample in saline solution as soon as possible. Do not mix areas where samples are collected. Above all, avoid contaminating the samples by re-using collection tools. Collecting Evidence All items that were found in the crime scene should be collected. The collecting officer should not decide whether a certain item is relevant or irrelevant. Small pieces of evidence also must have to be given importance, thus collecting them is necessary. Marking of Evidence  As evidence is collected, it is individually marked with the initials of the investigator. The marking tool depends upon the nature of the evidence. 1. A sharp-pointed steel used in scratching and engraving the initials of investigator in hard object such as metals collected in the crime scene. a. Crow bar b. Steel pen c. Stylus d. Bracer Marking of Evidence 1. Mark with initials of recovering officer. 2. Never use “X”. 3. Record any serial number (if applicable) and other distinctive mark. 4. Mark the object without damage. 5. Always mark the container in which the object is placed even if object itself is already marked. 6. When tags are used, make corresponding entry in the tag and attach it securely to the object Methods of Marking Specific Evidence 1. Revolvers & pistol : barrel, frame, butt, cylinder, and stock. ***For revolver, put tape around its bore and frame with signature of the investigator. ***For pistol, put tape around it with signature to avoid changing the parts of the gun. 2. Rifles: barrel, frame, magazine, bolt or slide. All magazines and accessories shall also be marked. 3. Fired Empty Shells, Misfired Cartridges: inside the mouth. If impossible, marked on the side of the body of the shells, not on the base. 4. Bullets/ Slugs/ Balls/ Pellets: ogive or nose/base. ***The initial name of the investigator and date should be marked on those parts so that the rifling marks found in the bullet or slug will not be disturbed because they are very important for ballistic examination Tagging of Evidence When evidence which by their nature could not be marked on each surface such as blood, hairs, fibers, they are placed in the plastic container where that container is then marked, we call such practice as tagging the physical evidence with the use of card where the initials of the investigator, date and time of collection, specific case and other information can be written. Preserving of Evidence Perishable materials should be preserved along the way or the preservation is in order to reach the court in the same physical condition as when they where collected from the crime scene. This is the work of a laboratory technician. However, evidences pass through several persons for several purposes. The principle of chain of custody must be observed. ***Chain of custody - the number of persons who handled and possessed the pieces of evidence the moment that they were collected, marked and tagged, up to the time of the final disposition of the case. What is meant by reconstruction of the crime? After completion of the search, an effort must be made to determine from the appearance of the place and its objects what actually occurred and what the circumstances of a crime were. 1. Physical Reconstruction—the physical appearance of the crime scene is reconstructed from the description of witnesses and the indication of the physical evidence. 2. Mental Reconstruction—from the physical reconstruction, some conclusions can be made concerning the consistency of the accounts of various witnesses. No assumption should be made concerning actions which are not supported by evidences. The final theory developed by the investigator should provide a line of investigative action.

Tribal mark is placed in the exposed parts of the body and used to identify person or membership of a tribe or social group. 11.Sexual Organ – Male organ may show previous circumcision. In female, the uterus and breasts may show signs of previous pregnancy. 12.Blood Examination – Blood type, disease, parasitic infection or toxic substances present may be utilized to distinguish one person from another. Light Factors in Identification are: 1. Clearest Moonlight or Starlight: Experiments have shown that best know person cannot be recognized by the clearest moonlight at a distance greater than 16 to 17 yards and by starlight any further than 10 to 13 yards. 2. Broad Daylight: A person can hardly recognized another person at a distance farther than 100 yards if the person has never been seen before, but persons who are almost strangers may be recognized at a distance of 25 yards. 3. Flash of Firearm: Although by experiment, letters of 2 inches high can be read with the aid of the flash of a caliber.22 firearm at a distance of 2 feet. 4. The flash of lightning produces sufficient light for the identification of an individual provided that the person’s eye is focused towards the person he wishes to identify during the flash. 5. In case of artificial light, the identity is relative to the kind and intensity of the light. Experiments may be conducted for every particular artificial light CRIME SCENE SKETCHING AND MEASUREMENTS IMPORTANCE OF SKETCHES 1. useful in questioning of suspects and witnesses 2. useful in the writing of investigative reports 3. excellent companions to photograph. ***Where photographs provide exact details, sketches offer accurate information about the placement of objects and they show relationship and distances between things. ADMISSIBILITY OF SKETCHES The word sketch means to draw to scale, with important dimensions at the scene being shown to a good degree of accuracy. Legally, for a sketch or diagram to be admissible in court, it must: Be part of some qualified testimony; Relate the observed situation (the person must have seen the area express it (the crime scene) correctly. IMPORTANCE OF SKETCHES Sketches are useful in questioning of suspects and witnesses as well as in the writing of investigative reports Sketches are excellent companions to photograph. Where photographs provide exact details, sketches offer accurate information about the placement of objects and they show relationship and distances between things. Rough Sketch - A type of sketch made by the investigator at the crime scene which is full of important details but without the scale of proportion. Finished Sketch Sketch with a scale of proportion and drawn by a draftsman which can be used for court presentation. Rough and finished sketches if requested by the court shall be presented by the draftsman to clear doubts of the jury REASONS OF MAKING SKETCH 1. To refresh the memory of the investigators. 2. To express the precise location of objects and their relationship to other objects and its surroundings. 3. To assist the prosecutor and the judge in understanding conditions at the crime scene; 4. To supplement photographs; 5. To assist in questioning of witnesses and suspects. Types of Sketches a.Sketch of Locality This illustrates the scene of the crime with the nearest physical surroundings, such as the room adjacent or opposite the room of the crime scene, the number of floors of a building or house, the yard and the other natural structures. b.Sketch of Grounds deals with the vicinity of the CS i n rel ation to the envi rons, to i ncl ude nei ghbori ng bui ldi ngs,structures,ormeans ofaccess l eadi ng to the scene. c.Sketch of Details appli ed i n conflagrations (arson),to i ndi cate the ori gin ofthe fi re. d.Cross Projection i ncludesthe posi scene.Itdescri wascommi ti onsand exactl besthe immedi tted and the detai l ocationsofthe physi ate scene onl sofitemsi yl i calevidence in the cri ke the room where the cri n the room. me me describesthe immedi ate scene onl y,specifi callyinside a room as the scene ofthe cri me.

Compass direction (orientation) - A standard arrow to indicate the north direction. To find the north without compass, determine the east where the sun rises. Facing east, your LEFT SIDE is the north direction. 2. Name of victim – the part of the sketch where name of the victim is written 3. Name of suspect – refers to the part of the sketch where the name of the suspect is written. 4. Legend - This is usually placed at the bottom of sketch outside the sketch of the scene. Numbers represent the objects in the crime or letters in order not to unnecessarily crowd the graphic presentation. Their descriptions are found in the legend. 5. Signatory – the part of the sketch where the name of the sketcher and the team leader or the officer in charge are written and signed. 6. Date and time- refers to the exact time the sketch was made.

Numbers represent the objects in the crime or letters in order not to unnecessarily crowd the graphic presentation Elements of a Sketch 1. Measurements - This is an element of sketch wherein measurements are shown in the sketch to show accurate spaces and distances of relevant objects to their point of reference. 2. Essential Items - All items in the scene must be included. Never decide outright that some items are irrelevant. As you proceed in the investigation, these seemingly irrelevant items will become relevant or material in the investigation. 3. Victim’s Identification - This includes the name of the victim. Other identification data may be included if available such as: birthdate and birthplace. 4. Time and Date - It includes the exact time of the preparation of the sketch but most importantly the time and date of the occurrence of the crime should be recorded. 5. Sketcher’s Name and Signature - This is so important to be included in the sketch to aid the memory of the investigator on case Type of Measurements Triangulation Method - An object is located by drawing two straight lines from two fixed points creating a triangle; the object is in an angle formed by the line. Rectangular Method - This method uses two walls in a room as fixed points, from which distances are measured at right angle to the object. Baseline/Coordinate - The baseline method also known as coordinate method, uses the principle of measuring an object between two known points. This single reference line is called the baseline. The baseline can be a wall or the known center of the room. The measurement of the evidence is taken in the following manner. A starting point is decided on one of the ends of the baseline. From that point, a measurement is made to the point that is right angle to the evidence. A second measurement is then taken from the object to the baseline. Type of Measurements Polar Coordinate Method - One permanent object is chosen and with the use of a compass, the direction of the object to be measured is determined. Compass Point Method - A protractor is used to measure the angle between two lines. One point along a wall is selected as the origin. An axis line drawn from the origin is the line from which the angle is measured. Grid Method - Starting at a known permanent reference point at the scene, a measurement of predetermined increments is marked off horizontally and vertically. On each horizontal and vertical increment, a line or string is laid so that the scene resembles many small squares. When a piece of evidence is found it is recorded to the nearest increment from the reference point. A measurement from the increment to the evidence is taken horizontally and vertically. CRIME SCENE SEARCH WHAT IS CRIME SCENE? “Treasure Island”. ***several pieces of evidence are mostly found at the crime scene, which are very relevant for the solution of the crime. Crime scene is the place where essential ingredients of the criminal act took place. Other terms: Crime Scene Investigation--Methodologies which involve recovery of physical and testimonial evidence for the purpose of identifying the witnesses, and arrest of perpetrator(s) for prosecution. Scene of Crime Operation (SOCO)-A forensic procedure performed by the trained personnel of the PNP Crime Laboratory SOCO Team through scientific methods of investigation for the purpose of preserving the crime scene, gathering information, documentation, collection, and examination of all physical and other forensic evidence First Responder (FR) -are members of the or other law enforcement agencies who are mandated and expected to be the first to respond to calls for assistance in cases of incidents of crime. Principles: Locard Principle, “Whenever two things touch each other, there is always a transfer of material from one to the other. Any contact between the criminal and the victim or the crime scene will leave trace evidence on both”. Jones Principle, “A number of individual similarities that are each of low evidentiary value, yet which all point to the same conclusion, can be just as important evidence as a fingerprint.” Crime Scene Locations 1. Indoor crime scenes - affords the crime scene protection from weather. allows to take time and process the scene in a slow, methodical manner without concern for weather influences. 2. Outdoor crime scene - most vulnerable to weather condition 3. Nighttime outdoor crime scene- presents the most problems 4. Crime Scene in Vehicles CRIME SCENE RESPONDERS AND THEIR DUTIES Officer-in-charge/ Team Leader – The one who directs the processing of the crime scene. Assistant Team Leader – The one who implements or executes the order/s coming from his/her superiors. Photographer – Takes photograph of all pieces of evidence that are relevant to the crime committed. Sketcher – Make sketches of the immediate, background and inside the scene of the crime. CRIME SCENE RESPONDERS AND THEIR DUTIES Master note taker – The one who writes down in short hand all observations at the crime scene such as: weather condition, time of dispatch and time of arrival at the crime scene and other relevant data that should be noted. Evidence Man – The one in charge in the collection, preservation, tagging of the articles of evidence found at the crime scene. Measurer – Makes all relevant measurements of the scene such as: the distance of the body of the victim to the firearm used; in motor vehicle collision, the distances of the two vehicles to the points of references.
