Study Notes

General Consideration of Investigation

Investigation refers to a thorough examination or inquiry, often systematic and official, aimed at uncovering facts or individuals.
The term derives from the Latin "VESTIGARE," meaning to trace or probe, linked to "VESTIGIUM," which translates to "footprints," indicating a search for traces.

Criminal Investigation Definition

Benette defines criminal investigation as the quest for facts surrounding a crime to establish the truth and assign responsibility.
Agas and Cael highlight that it involves collecting and analyzing relevant facts to identify the guilty party and provide admissible evidence.
Described as an art, it is guided by intuition, inspiration, and a minimal amount of chance.
Hans Gross attributes 95% of criminal investigation to "perspiration," 3% to inspiration, and 2% to luck.
As a science, it applies forensic knowledge to gather, process, and evaluate physical evidence.

Goals of Criminal Investigation

Determine if a crime has been committed.
Legally obtain information and evidence.
Identify individuals involved in the crime.
Arrest suspects connected to the crime.
Recover stolen property.
Present a robust case to the prosecutor.

Types of Criminal Investigation

Conducted while the suspect is under arrest or in detention.
Conducted when the suspect is "at large," meaning they are not currently wanted by law enforcement.

Phases of Investigation

Preliminary Investigation

Promptly and safely proceed to the crime scene.
Provide assistance to any injured individuals.
Arrest criminals as necessary.

In-Depth Investigation

Involves following leads from the preliminary investigation.
Revisit the crime scene for further analysis.
Conduct interviews with existing and new victims and witnesses.
Process additional documents and gather facts.

Concluding Investigation

Directly follows preliminary and in-depth phases.
The investigating officer collaborates closely with the prosecutor to prepare the criminal case for trial.

Key Principles in Criminal Investigation

Recognition/Identification: Identify relevant data and physical evidence pertaining to the case.
Collection: Gather significant data and physical evidence, such as blood samples or witness accounts.
Evaluation: Determine the probative value of collected evidence.
Preservation: Maintain the integrity of evidence throughout the investigation.
Presentation: Effectively present the gathered evidence in legal proceedings.

Location and Time: Defines status (current or past) and specific date/time of the incident.
