Presentation Transcript

  1. Tarrant County Medical Examiner’s District Dr Nizam Peerwani, Chief Medical Examiner Roger D Metcalf DDS Human ID Lab 200 Feliks Gwozdz Place Fort Worth, Texas 76104-4919 817-920-5700 ext 160 rmetcalf@tarrantcounty.com, rmetcalf@leo.gov

  2. Databases Used by Forensic Odontologists at T.C.M.E.

  3. N.C.I.C.dental profile • J.P.A.C. Odontosearch(Joint POW/MIA Accounting Command—formerly C.I.L.HI.) • Lexis/Nexis law enforcement package

  4. N.C.I.C. has capability to store a missing person’s or an unidentified body’s dental profile. • Unfortunately, up until a couple of years ago, there was a “bug” in the software, and dental profiles were not being searched automatically.

  5. There is no “national dental database” that forensic odontologists can search—the F.B.I. is currently studying implementation of a dental image repository that would be an extension of N.C.I.C. • The hope is someday we will have a searchable dental database similar to A.F.I.S.

  6. The U.S. Army maintains a database—Odontosearch—that helps odontologists determine the uniqueness of a particular arrangement of fillings a person may have. • Central Identification Laboratory at JPAC (formerly C.I.L.HI.) http://www.jpac.pacom.mil/CIL/OdontoUse.htm

  7. The odontologist enters the dental profile of the subject into the Odontosearch program, and the program searches various databases to determine how often that particular profile occurs in a particular population

  8. Useful for dental id cases, but not helpful for bitemark cases—unfortunately, dental id cases are not often litigated, while bitemark cases are often highly contentious

  9. Lexis/Nexis is a huge database company that maintains all sorts of databases used primarily by the legal profession • They maintain public record information on individuals from “civilian databases”

  10. The Lexis/Nexis law enforcement package gives us access to SSNs, DLs, various other licenses, VINs, limited criminal history information, and, most importantly, potential relatives and associates—and the capability to do reverse lookup with only limited information about the subject

  11. Disclosure—we have no financial or other connection to Lexis except as a customer • There are several other similar, competing products—ChoicePoint, Acxiom, et al, and I believe Westlaw also has some of these features, as well

  12. Please drive carefully!
