Study Notes
Fingerprint Identification
- The clarity of impressions can influence fingerprint identification.
- Fingerprint examiners' experience plays a vital role in identification.
- Only a part of the fingerprint is needed for identification through the uniqueness of formations.
- In fingerprint terminology, ACE-V refers to Analysis, Comparison, Evaluation, and Verification.
- Monozygotic twins share identical DNA but have unique fingerprints.
- Dactyloscopy is a system of personal identification using fingerprints.
- The principle of permanence in fingerprints refers to them remaining unchanged from the womb to the tomb.
- Fingerprint analysis can be used both to identify perpetrators and provide evidence in investigations.
- Subcutaneous glands secrete sweat that leaves fingerprints.
- Tracing ridges on a fingerprint helps identify specific patterns, such as loops and whorls
- The type line is the ridge that separates patterns.
- The delta is the point where a pattern's type line diverges towards the core, providing crucial information about the pattern.
Fingerprint Patterns
- Loops, whorls, and arches are common patterns found in fingerprints.
- The loop pattern has diverging and converging ridges that enclose the pattern area.
- The space between the shoulders of a loop, free of any appendage, is known as the "sufficient recurve."
Latent Fingerprints
- Latent fingerprints are invisible impressions that are found at crime scenes
- Powder is applied to latent fingerprints at a crime scene to make them visible.
- The process of lifting a latent fingerprint involves securing the area, photographing it, and applying powder.
Missing Persons
- Physical descriptions, clinical history, and personal traits are vital information for locating a missing person.
Identification of Unknown Dead Bodies
- When identifying an unknown dead body, fingerprints are the most dependable method.
- Scars and tattoos can also be used for identification, but body measurements may be less reliable.
General Forensic Information
- Blood grouping uses antibodies (anti-A, anti-B) to determine blood types:
- A reaction to both anti Serum A and B indicates Type AB blood
- No reaction to either anti Serum A or B indicates Type O blood
- A reaction only to anti Serum A indicates Type A blood
- A reaction only to anti Serum B indicates Type B blood
- The chemical substance found in all cells, passed down from parents to children, is DNA.
- The rate of human hair growth is approximately 0.4 to 0.5 mm per day.
- The tips of hair can be examined to determine if they were cut, bent, or folded.
Poisoning
- Poison can be rapidly absorbed through the modes of administration, including oral, anal, inhalation, and injection.
- The presence of nitrite in a firearm can be detected through the diphenylamine reagent, which turns blue when exposed to recent firing.
- Posology is the study that deals with the form and quantity of medicine within a certain time.
Forensic Firearms
- DPA solution is used to identify a person who fired a gun.
- Blue specs and tailing are indicators of a positive result for DPA solution.
Evidence Collection and Preservation
- Evidence must be properly preserved in a way that prevents its degradation.
- To maintain the integrity of the evidence, it should be collected and stored in a manner that minimizes contamination, loss or damage.
- Proper packaging and labeling of evidence are critical for chain of custody.
- The primary purpose of proper evidence preservation is to ensure that the evidence can be presented in court.
Document Examination
- Document examiners use scientific methods to determine the age and authenticity of a document.
- This analysis can be destructive, due to the application of chemicals.
Fiber Analysis
- Fiber analysis is the study of textile fibers.
- There are two main types of fibers: animal and plant.
