Expert Witness - S14.E21

In 1993, young mother Tammy Tatum was found sexually assaulted and murdered in her Longmont, CO apartment. Police initially suspect her estranged husband, but did not have enough evidence to charge him and the case went cold. Three years later, another young woman was raped and police suspect the cases may be related. Despite meticulous washing of the crime scene, a single hair remains to lead authorities to the culprit.
