Davon Dwayne Whitlock was 18 when he was found shot to death on March 24, 2015, inside a home on the 3100 block of North Harding Street in Indianapolis. Three other people in the house were also killed that night: Whitlock’s mother, 41-year-old Terri Betties; his cousin, 32-year-old Tiara Turner; and a family friend, 48-year-old Sherri Taylor.

The case went cold for years. In January 2019 Marion County prosecutors charged 36-year-old Nicholas Dunn, then serving a weapons sentence, with four counts of murder after what they described as new evidence. Those charges were dropped in July 2022 after two key witnesses died and DNA evidence from the scene was found to be compromised and inadmissible. Prosecutors noted Dunn’s DNA had been recovered on a bottle and cigarette butts but treated that as circumstantial because he had admitted prior presence in the home. The charges were dismissed without prejudice and no one is currently in custody.

Does anyone who knew Davon or the other victims have information that could help move this investigation forward?
