Cold Case Unit

Print

District Attorney Jeff Rosen re-established a Cold Case Unit in 2011, to assist county law enforcement agencies with the investigation of unsolved homicides and sexual assaults. 

The mission of the Cold Case Unit is to assist all county law enforcement agencies in bringing violent offenders to justice. Toward this goal, the District Attorney has asked every county law enforcement agency for access to unsolved murder and sexual assault cases in order to assist with locating and submitting biological evidence, interviewing witnesses, and conducting a comprehensive case evaluation. Mr. Rosen, as well as Santa Clara County Sheriff and the Chiefs of Police, have signed a Cold Case Partnership and Cooperation Agreement.

The County Crime Lab also joined this partnership, and made a commitment to handle DNA in an expedited fashion. This commitment will assure that laboratory backlogs will not cause further delays for family members and loved ones who have often waited years for justice.
