When is Forensic Testing Required?
• Identify potential suspects.• Exonerate wrongly accused people.• Identify catastrophe victims. • Establish paternity/family relationships. • Identify endangered/protected species. • Detect bacteria and other organisms.• Match organ donors with recipients.• Determine pedigree for seed or livestock.• Authenticate consumables.

What is a DNA Fingerprint?
• Profiling, Testing, Typing or Genetic Fingerprinting are Synonymous.
• Saliva, Sperm, Blood, Hair, Skin Cells, or Human Tissue Samples.
• Encrypted Sets of Numbers That Reflect a Unique DNA.

What is the DNA Databank?• COmbined DNA Index System aka “CODIS” Blends Computer and DNA Technologies.
• FBI-Managed Dual Index System of Convicted Offender and Forensic Indexed Databases.
• 5 Million DNA Profiles in 2007.
• 500,000 DNA Sample Backlog in 2007.

DNA Standards and Uniqueness• FBI Sets the Standard w/13
Genetic Markers or LOCI.
• There are Between 4 and 40 Variations of LOCI.
• 1 in 5B Chance of Matching.
• DNA Forensics are Superior • to Eyewitness or Fingerprints.

Handling DNA
• Understanding the Lab Report: The First Item you Need in a DNA Report
• Looking Behind the Lab Report: Are the Laboratory's Conclusions Fully Supported by the Test Results?
• Chain of Custody
