South Carolina police believe they have identified the killer behind the murders of three women, an attempted murder, and the beating of another women across four states by using DNA technology, Greenville News reports. Greenville Police Chief Ken Miller announced that Robert Eugene Brashers was responsible for the 1990 cold-case murder of Genevieve Zitricki, who was found “beaten and strangled to death” in her bathtub. Brashers, who died from a self-inflicted gunshot wound in 1999, was found through the work of Parabon NanoLabs with DNA samples from his family and his exhumed body. While authorities previously made a DNA connection between the Zitricki murder and the 1998 murders of a mother and daughter in Missouri, they were unable to reveal Brashers identity until recently. A few hours after the Missouri murders, Brashers allegedly shot a woman in Tennessee and tried to force his way into her home. The woman survived the incident. Brashers also served over three years in prison for beating and shooting a woman in Florida a year before he killed Zitricki.
