 Just eight months later, he struck again and two sisters, Kati and Kristin Lisk disappeared. The bodies of the 12- and 15-year-old were found less than a week later, floating in a river. The only clues were a few pink and dark blue fibres and a couple of strands of hair. Special Agent Doug Deedrick, an FBI trace evidence expert, lead the forensic investigations on the case. He told ABC : "I said, 'Pink fibres, I think they look like a bath rug of some type.' Everyone was looking for this pink bath rug for me. Kathryn Nicole 'Kati' Lisk Kristin Michelle 'Kristi' Lisk "With Sofia, for instance, I had some dark blue acrylic fibres that I was looking for because I found the same types on Kati and Kristin. And when I turned Sofia's shirt inside out, I actually pulled off eight or nine blue fibres." A massive hunt was launched, with details of the cases cross checked with hundred of other open files. Eventually Evontiz made a mistake. He was tracked down by police after Kara Robinson, who was 15 at the time of her abduction by Evonitz, manage){kind=link}
An ‘obsessed’ FBI agent had a hunch that connected the murders of a number of girls. Just a few fibres on their bodies led investigators to killer Richard Marc Evonitz
Unlike the movies it’s rarely a moment of revelation when a serial killer is caught but rather a number of small clues that lead investigators to the perpetrator.
In the case of the serial killer Richard Marc Evonitz, the clues that connected him to a number of deaths were particularly small.
Three girls are known to have been killed by Evontiz during the 1990s but before his death he confessed to his sister to even more victims.
His first victim was 16-year-old Sofia Silva who was abducted while sitting on her front porch doing homework in Spotsylvania, Virginia.
