    Study Notes

    Forensic Science History and Careers

    • Forensic science uses science to resolve legal issues, such as crimes.
    • A Forensic Science Investigator is interested in collecting, examining, and reporting evidence results to law enforcement. They might testify in court about their findings.
    • The forensic science examiner documents and identifies evidence, determining its significance.
    • Forensic scientists gather, document, and determine the type of evidence necessary for a case.
    • Excellent communication skills are crucial for forensic scientists to prove their points to a jury.
    • Forensic scientists and police officers both use analytical skills to identify a problem, isolate it, and draw appropriate conclusions.

    Significant Events

    • 1967: Paul Ekman identified over 10,000 facial microexpressions and 3,000 emotions associated with non-verbal communication.
    • 1974: Elizabeth Loftus explained how misinformation can lead to false memories.
    • 2012: Scott Fraser described the fallibility of memory reconstruction.
    • 2014: Pamela Meyer published work on detecting lies.
    • 2016: Techniques for interrogating witnesses and suspects were modified.

    Observation and Perception

    • Observation is the act of using senses to perceive.
    • Our brains filter and process sensory information, focusing on what seems important.
    • Perceptions may not always be accurate due to limitations in what is seen, heard, and perceived.
    • Eyewitness observations can be faulty due to factors like anxiety, prejudices, and personal beliefs, interfering with accurate memory recall.

    Eyewitness Accounts

    • Eyewitness accounts of a crime scene can vary considerably.
    • Memory of details fades with time, and our brains fill in gaps.
    • Forensic investigators must distinguish between facts and opinions.
    • After an eyewitness account, investigators sequence facts into a logical pattern.

    Improving Observation Skills

    • Natural inclination is to filter unimportant details.
    • Effortful observation of every detail is necessary.
    • Interpretations should be held until all information is gathered.
    • Documenting and photographing events helps with accurate memory recall.

    Forensic Science Timeline

    • 250 BC: Erasistratus observed increased patient pulse rates at death.
    • 1247: Sung Tzu wrote about using medical forensics for investigations.
    • 1840: Mathieu Orfila's work on detecting arsenic poisoning established toxicology.
    • 1883: Alphonse Bertillon invented anthropometry for criminal identification.
    • 1892: Francis Galton classified fingerprints.
    • 1910: Edmond Locard established the first police crime lab and identified the Locard Exchange Principle.
    • 1920s: Luke Way published a book on identifying objects.

    Careers in Forensic Science

    • 1937: Walter Specht developed luminol for detecting blood.
    • 1950: Max Frei and Sulzer used tape to lift trace evidence.
    • 1974: Gunshot residue analysis was developed.
    • 1984: Sir Alec Jeffreys developed DNA fingerprinting.
    • Crime Scene Investigators analyze crime scenes, collect evidence, and process it.

    Trace Evidence Examination

    • Examines physical evidence like hair, fibers, etc through physical and chemical analysis.
    • Latent Print examiners lift and analyze fingerprints with chemicals.
    • Forensic serologists and biologists examine and interpret biological evidence like blood.

    Forensic Toxicologist

    • Examines body fluids for drugs and poisons.

    Questioned Document Examiner

    • Examines handwriting and typefaces to establish authenticity.

    Other Forensic Specialists

    • Firearm Examiners examine firearms and ammunition.
    • Forensic Entomologists study insects to determine time of death.
    • Forensic Computer Scientists analyze digital devices.
    • Forensic Engineers analyze failures and reconstruct accidents.
    • Forensic Odontologists identify and match dental evidence.
    • Forensic Pathologists identify cause and time of death.
    • Criminologists study criminal behavior.

    Forensic Science and Law

    • Evidence is presented to a trier of fact (judge or jury).
    • Ethical codes, like the American Academy of Forensic Sciences' guidelines, are important.
    • Annie Dookhan's case exemplifies the importance of ethical conduct.
