  2. Human Id Laboratory • Director and Odontologist • Roger Metcalf, D.D.S. • Anthropologist • Dana Austin, Ph.D. • Fingerprint Examiners • Bill Bailey • Bill Walker • Interns • Paul Coffman & Others

  3. TCME Unidentified 12/5/07 • 59 males / 12 females / 1 unknown • Currently 73 cases from 1982 – 2007 • 17 different law enforcement agencies • 19 homicides /26 undetermined / 1 unk • Better for assistance from law enforcement • 15 accidental / 9 natural / 3 suicide • Can mean less interest from LE

  4. Protocol for Cold Cases • Case file retrieval and review • Files retained in Anthropology laboratory • NCIC entry or modification • Modification of biological profile • Addition of dental codes

  5. Protocol for Cold Cases • CODISmp sample submission • Blood swatches/cards • Bone • Paraffin-embedded tissue blocks • Known hair samples • Fingerprints • Classification entry into NCIC • Upload into AFIS/IAFIS/IDENT • Follow-up with possible matches • $M messages from NCIC • Leads from networks or citizens

  6. Additional Measures • Scan photos and submit to internet based databases • Tattoos • Facial photos • Facial Reconstruction • Clay reconstruction from skulls • Sketches from body photos • Enter into other databases • UDRS • Doe Network

  7. Manpower ! • Grant Funded Part-time Employee • Employment period 2 mos. • Began June 4, 2007 • 1st identification June 20, 2007 • Two ids on July 13, 2007 • Grant extension expired July 30, 2007 • 3 additional id’s since he left • Application in for Jan-Jun, 2008

  13. 4 Years Unidentified • 2003 John Doe • Fell or jumped from downtown parking garage • Thumbprints searched through TX DPS AFIS database

  14. 2007 Resolution • Fingerprints were run again through TX DPS AFIS system • Candidate search identified decedent this time

  15. What did we miss? • Fingerprint did not hit in AFIS in 2003 • If fingerprints are still available it is worth the time to try again • Different fingers may produce a positive result

  16. Dec. 1994 Train-Pedestrian • Train unable to stop, body on tracks • Young Hispanic male • Handwritten notes in pocket possibly indicate suicide • Train ticket from Dallas to Ft Worth for 2 days earlier • Fingerprints checked with no results

  17. July 2007 • Call from UNTHSC DNA Identity Lab • Cold hit on our 1994 John Doe • TCME submitted Blood swatch 3/06 • Family reference sample submitted by LE 2/06 • 7th cold hit for UNTHSC • Family notified in person by LE

  18. TX Missing Persons DNA Database • Housed at UNTHSC in Fort Worth • Funded by State Legislation in 2001 • Extractions begun March 2003 • Accepts cases of unidentified remains and relatives of missing persons • First lab to use CODISmp software

  20. National Missing Person DNA Database (NMPDD) • 2005 data Profiles for Unidentified/Missing • 158 Missing Persons • 415 Relatives of Missing Persons • 203 Unidentified Remains • Current numbers (July 07) are less than 5000 combined

  21. What did we miss? • Family reported him missing to the local PD • No NCIC entry • No check with the MEO • Family continued to follow-up with their local PD • We had a train ticket with his last name and did not look at MPCH webpage for that name • MPCH webpage had his date of disappearance off by one year

  26. AFIS/IAFIS • Most states have AFIS database run by State Police or DPS • When we search through TX AFIS we are searching only the TX database • IAFIS (Integrated Automated Fingerprint Id System) combines fingerprint databases from contributing state & federal agencies • Maintained by the FBI • Access by law enforcement agencies

  36. What did we miss? • Donna Williamson disappeared in 1982 when she was 19 years 11 mos old • MP & UNID profiles were in NCIC. Donna was eliminated as possible because her dental was entered reverse left-right

  37. Missing Person Clearinghouses • Each U.S. state, Puerto Rico, and Canada have some type of clearinghouse • If you are active in MP or Unid cases, get to know your clearinghouse personnel • Individual states vary in their level of resources and services • NCMEC provides training, technical assist, & communication to clearinghouses • http://www.missingkids.com/missingkids/servlet/ServiceServlet?LanguageCountry=en_US&PageId=1421
