Study Notes
Introduction to Forensic Science
- Forensic science is the application of scientific methods to solve crimes.
- The American Academy of Forensic Science (AAFS) has 10 sections, each focusing on specific areas.
- Anthropology studies bones to determine age, race, and sex of individuals.
- Criminalistics encompasses all aspects of crime lab work.
- Digital/Multimedia analyzes phone and computer evidence, recognizing the role of technology in crimes.
- Questioned Documents examines handwritten notes, ransom notes, and similar materials.
- Engineering and Applied Science investigates structural failures to determine if they were accidental or intentional.
- General Psychiatry and Behavioral Science examines the mental health of individuals involved in crimes.
- Jurisprudence focuses on the scientific application of the law.
- Odontology analyzes teeth, especially bite marks.
- Pathology/Biology examines bodily fluids and skin samples.
- Toxicology investigates the presence and effects of poisons, not limited to drugs.
- Locard's Exchange Principle states that whenever two objects come into contact, they exchange materials. This principle is fundamental to linking suspects to crime scenes.
- Microscopy is a crucial tool in forensic science, with Walter C. McCrone being a prominent advocate for its application.
- Firearms Examination involves comparing bullets with those test-fired from suspected weapons using a comparison microscope, a technique refined by Calvin Goddard
- Modern Scientific Advances such as chromatography, spectrophotometry, and electrophoresis enhance the precision of substance identification and connect minute evidence to individuals and locations.
- DNA Profiling is a significant modern advancement in forensic science, pioneered by Sir Alec Jeffereys.
- DNA Databases are used to store fingerprints, bullet markings, shell casings, and DNA for identification purposes.
Crime Laboratories
- The first crime lab in the United States was established in 1923 by August Vollmer.
- The oldest crime laboratory in the U.S. was created by police chief August Vollmer.
- Paul Kirk was a prominent figure in the field, leading the criminalistics department.
- Crime labs operate at local, state, and federal levels, with varying sizes and services.
- The prosecution of criminal cases relies on the cooperation of forensic experts and police investigators.
- DNA analysis plays a crucial role in the public's perception of modern crime laboratory capabilities.
Forensic Science Services
- Forensic Anthropology studies skeletal remains to determine age, sex, ethnicity, and medical history of individuals.
- Forensic Engineering investigates structural failures to determine if they were accidental or intentional and identifies those responsible.
- Forensic Odontology uses dental evidence, such as bite marks or dental records, to link suspects to crimes and identify victims.
- Forensic Entomology analyzes insect activity on mortal remains (feeding, egg laying) to estimate the time of death.
- Forensic Pathology applies medical knowledge to determine the cause of death, often involving autopsies.
Crime Scene Investigation
- Sketching is a crucial part of crime scene documentation, providing a scaled and accurate depiction of the scene and object positions.
- Notes are essential for documenting all actions, findings, and evidence collected during the scene processing.
- Physical Evidence must be collected and stored carefully to preserve its integrity for analysis.
- Systematic Searches are crucial for ensuring that all relevant evidence at a crime scene is collected.
- Photography serves to document the crime scene before and after evidence collection.
Case Studies
- The Ted Bundy case highlights the importance of forensic evidence, such as bite marks, in linking suspects to victims.
- The Anthrax Letter case exemplifies the diverse range of services provided by crime labs, including DNA testing, handwriting analysis, and ink analysis.
- The Colin Pitchfork case demonstrates the power of DNA profiling in identifying criminals and exonerating innocent suspects.
- The use of DNA profiling was first used in the Colin Pitchfork case, and he was the first person to be exonerated of murder through the use of DNA profiling.
- The DNA Manhunt in the Pitchfork case illustrates a large-scale effort to collect and test DNA samples from a large population.
- The case of John Wayne Gacy highlights the use of forensic anthropology to identify victims from skeletal remains.
Key Figures
- Locard: Developed the principle of exchange, a cornerstone of forensic investigation.
- Walter C. McCrone: Advocated for the use of microscopy in forensic science.
- Calvin Goddard: Refined firearms examination techniques using a comparison microscope.
- Sir Alec Jeffereys: Developed the first DNA profiling test.
- August Vollmer: Established the oldest crime laboratory in the United States.
- Paul Kirk: Led the criminalistics department.
