  1. Chapter 22: The DNA Databases Forensic Biologyby Richard Li

  2. Basics • Developed to assist in solving violent crimes by creating a network for the exchange of information • Compare DNA profiles electronically • National DNA Database (NDNAD) • Combined DNA Index System (CODIS) Forensic Biology by Richard Li

  3. The National DNA Database • U.K. • World’s First-1995 • Largest number of profiles in proportion to the population • Indexes • Crime Scene Samples • Offender Samples Forensic Biology by Richard Li

  4. The National DNA Database • Entries • Anyone arrested and detained in connection with a recordable offense • Feb. 2006 • 3.4 million offender profiles • 290, 000 crime scene profiles Forensic Biology by Richard Li

  5. Combined DNA Index System • U.S. • 1998 • All 50 states participate • Infrastructure: • Local DNA Index (LDIS) • State DNA Index (SDIS) • National DNA Index (NDIS) Forensic Biology by Richard Li

  6. Combined DNA Index System • Indexes • Forensic Index (crime scenes) • Offender Index • Entries • 4.5 million profiles of convicted felons • 170 ,000 forensic profiles • 1.5% proportion of the population • RFLP & PCR-based profiles Forensic Biology by Richard Li

  7. Applications • Hit- match made database • CODIS 48,500 (April 2007) • Investigation Aided • CODIS 49,400 (April 2007) • NDNAD 721,495 (Feb. 2006) • Ultimate Goal TO SOLVE CRIMES Forensic Biology by Richard Li
