In 1993, young mother Tammy Tatum was found sexually assaulted and murdered in her Longmont, Colorado apartment. Police initially suspected 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, but the DNA collected provides no answers. Years later, Rudy Gaytan is required to give a DNA sample upon leaving prison and his DNA links him to the rape. Eventually, he also confesses to the murder of Tammy Tatum.
