Study Notes
Forensic Science History and Careers
- Forensic science uses scientific methods to solve legal issues.
- A forensic science investigator focuses on collecting evidence, examining it, reporting results to law enforcement, and testifying in court.
- Forensic examiners document and determine the significance of evidence.
- Forensic scientists collect, document, and decide what evidence needs to be collected.
- Evidence collection includes gathering qualitative and quantitative data.
- Forensic scientists must be strong communicators to convince juries.
- Both forensic scientists and police officers have analytical skills like isolating problems and drawing conclusions.
Significant Events
- 1967: Paul Ekman identified facial microexpressions linked to emotions and nonverbal communication.
- 1974: Elizabeth Loftus explored misinformation and its impact on false memories.
- 2012: Scott Fraser described the fallibility of memory reconstruction.
- 2014: Pamela Meyer's work focused on detecting deception.
- 2016: Modified interrogation techniques for witnesses and suspects.
Observation and Perception
- Perception is when a person uses their senses to understand their surroundings.
- Instead of continuous data input, the brain filters information; meaningful information.
- Perception of sensory observations is processed internally.
- Perception depends on sensory input and internal processes; it might be inaccurate.
- Eyewitness memory is not always accurate.
- Anxiety, prejudices, and personal beliefs can impact eyewitness accounts.
- Eyewitness accounts can differ greatly, vary widely, and are less reliable over time.
- Forensic investigators distinguish between facts and opinions.
Improving Observation Skills
- Naturally, people tend to focus on what they expect as important or filter out apparently unimportant information.
- Training helps people to systematically observe, document, and consider a broad range of evidence.
- People generally interpret patterns in observations even with incomplete evidence.
- Observation and documentation of images and notes are helpful.
Forensic Science Timeline
- 250 BCE: Erasistratus observed increased patient pulse rates before death.
- 1247: Sung Tzu's book explored medical knowledge for investigations of death.
- 1840: Mathieu Orfila applied the Marsh test for arsenic detection.
- 1883: Alphonse Bertillon created anthropometry (body measurements) for identifying criminals.
- 1892: Sir Francis Galton classified fingerprints.
- 1910: Edmond Locard established the first forensic lab, outlining the Locard exchange principle.
- 1920s: Luke Way published on identifying tools and instruments from evidence.
Careers in Forensic Science
- 1937: Walter Specht developed luminol for blood detection.
- 1950: Max Frei-Sulzer used tape for lifting trace evidence.
- 1974: Gunshot residue methods were developed.
- 1984: Sir Alec Jeffreys developed DNA fingerprinting/profiling.
- Crime Scene Investigators (CSI) analyze, collect, and document evidence.
Trace Evidence and Examinations
- Trace evidence examiners compare physical evidence like hair, fibers, and blood.
- Latent print examiners lift and analyze fingerprints.
- Forensic serologists/biologists handle biologicals like blood and bodily fluids.
- Forensic toxicologists identify drugs and poisons.
- Questioned document examiners analyze documents for authenticity.
Other Forensic Specialists
- Firearm examiners analyze firearms and ammunition.
- Forensic entomologists study insects to estimate time of death.
- Forensic computer scientists examine digital evidence.
- Forensic engineers analyze accidents, fires, and explosions.
- Forensic odontologists use dental records for identification.
- Forensic pathologists determine cause and time of death through autopsies.
- Criminologists study criminal behavior.
Forensic Science and Ethics
- Evidence presented in court is vital for decisions.
- The American Academy of Forensic Sciences establishes an ethical code.
- Ethical concerns in forensic investigations are important.
- The Annie Dookhan case highlights ethical issues in forensic science.
