  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. State v. Tracey Ann Frame As Seen on Television!

  3. On 04/22/2002, autopsy performed at T.C.M.E. on unidentified remains • Remains were adult Caucasian male, burned badly • Decedent had been shot once through heart • Decedent had been wrapped in a blanket and tarp, then set afire

  4. What they said on CBS’s 48 Hours: “The medical examiner would determine that the victim was a man in his 40s, killed by a single gunshot wound to the heart, but his identity was a mystery. “Dental records later confirmed the body’s identity as 40-year-old David Nixon . . .”

  5. 48 Hours : Secrets & Lies on Grapevine Lake

  6. What they didn’t say— It took three weeks of hard work by the T.C.M.E. Investigators to get the remains identified.

  7. Rodney Crow, D.D.S., D.A.B.F.O., former Chief Forensic Odontologist, T.C.M.E., performed dental examination on remains and the first comparison with known dental records (treating dentist was Dr. David Nix) concluding decedent was indeed David Nixon. • Dr. Crow retired before Tracy Ann Frame’s trial, however, and was not available to testify.

  8. Mr. Sean Colston, Tarrant County Asst. D.A., requested a new comparison of dental records.

  9. 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.

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

  11. 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

  12. Bonus trivia question worth absolutely nothing whatsoever—can you guess what this object is in the radiograph?

  13. Please drive carefully!
