“We swabbed hundreds of people and ran that DNA against our unknown, and we came up unsuccessful,” Conroy said.
Sound familiar? Genevieve Zitricki was blitz-attacked in her bed while she slept. Police stated at one point that her killer knew her, but she did not know him. She was popular and outgoing.
It took 28 years to solve her murder, using a combination of Parabon NanoLabs, Genweb, genetic genealogy, DNA swabs from relatives who willingly provided it and DNA from other crime scenes. The police paid to exhume the remains of the suspected killer, who was a serial rapist and murderer. His wiki states that the victims physically resembled his wife, and had a similar haircut. He held his wife hostage in a hotel room days before he took his own life.
