SUMMARY:DNA databasing for forensic use\, Chaos & Complex Systems Semi
 nar\, Rohaizah James\, Promega Corp
DESCRIPTION:Genetic markers called Short Tandem Repeats (STR) is now r
 outinely used in forensic DNA testing to identify the source of crime 
 scene evidence. A DNA profile containing multiple STR's provides an ex
 tremely high probability of identity\, leaving little doubt that a mat
 ch between crime scene evidence and a suspect is not random. Because a
  large fraction of crimes are committed by repeat offenders\, an offen
 der database aids in generating leads and solving crimes. The national
  DNA database\, established in 1998 after Congress passed the DNA Iden
 tification Act\, now contains over 10 million offender DNA profiles. T
 he ability to search this database has aided over 200\,000 investigati
 ons. This database also includes over 1.5 million arrestee profiles. A
 rrestee DNA testing\, currently allowed in 29 states\, has been contro
 versial. Does the potential benefit of improving public safety outweig
 h an arrestee's privacy interests? What about familial searching\, whe
 re a database is searched to identify not the criminal but his/her bio
 logical relative? This search method was used successfully in solving 
 the California Grim Sleeper case\, where the presence of the criminala
 EuroTMs son in the DNA database led investigators to the father. This 
 presentation will include a discussion on the science behind STR analy
 sis and the practical questions it brings in forensic use.
