14 Trace Evidence

15 Locard Exchange Principle  The theory that anyone, or anything, entering a crime scene both takes something of the scene with them, and leaves something of themselves behind when they leave.

16 Types of Trace Evidence Fibers Hairs GlassPaint Soil Lubricant Makeup Arson Explosives Filament Mechanical Match GunShot Residue

17 Identification and Comparison 2. COMPARISON:  Obtain a control sample  Comparative Examinations of the Unknown Exhibit with a Control Sample to see if they originated from different sources.  Conduct all possible comparative examinations.  Conclusion: could the two samples have originated from a common source 1. IDENTIFY:  What is the Unknown Exhibit (glass, hair, paint, soil, fibers, metal, etc.)

18 Testify as an Expert Witness  Report: The end fragment of tape removed from the roll of tape found at the residence of the suspect (Exhibit #12) and the tape fragment removed from the knife (Exhibit #5) were at one time an integral unit.  GUILTY

19 DNA Analysis Its role in forensic science and the Hannah Graham Case

20 HANNAH GRAHAM MISSING STUDENT UNIVERSITY OF VIRGINIA STUDENT

21 “Person of Interest” in Hannah Graham case JESSE “LJ” MATTHEWS MET WITH POLICE THEN SPED OFF; LATER APPREHENDED

22 DNA Under Fingernails links suspect to 2005 case

23 Oct. 29 :REMAINS FOUND ARE HANNAH GRAHAM MATTHEWS AWAITS TRIAL

24 FORENSIC PSYCHOLOGY

25 What Do They Actually Do? Criminal Profiling Forensic Interviews/ Interrogation Forensic Polygraph/ Hypnosis Trauma Counseling Competency Evaluation Forensic Treatment Counseling Criminalist/ Cold Case Files Psychological Autopsy
