The Unidentified Persons and DNA Unit (UPDU) was created in September 2007 as a partner to the Missing Persons Clearinghouse (MPCH). The UPDU assists law enforcement agencies with cases involving homicide and the recovery of unidentified bodies. Personnel maintain a public web site in conjunction with MPCH that is used to disseminate information regarding unidentified persons. he UPDU also serves as the state's administrator coordinator for the FBI's ViCAP system, which tracks serial killers by providing a central repository for information and analysis of violent serial crimes. In addition, the UPDU coordinates the submission of DNA samples from unidentified human remains, which are then sent to the University of North Texas Health Science Center (UNT) HSC) Center for Human Identification in Fort Worth, Texas. The UNT HSC develops DNA profiles from the samples and enters them into the Human Identification Database, which can then compares profiles from missing and unidentified persons for possible matches. These profiles are can also be also compared to profiles contained in the FBI's national database.
