Derrick Bernard Turner was 43 when he was found dead in his Clearwater, Florida, home on June 24, 2014. Police reported multiple gunshot wounds and opened a homicide investigation after discovering no signs of forced entry, a detail that investigators said suggested Turner may have known his attacker.

Detectives interviewed friends, family and acquaintances while processing the scene, but progress stalled for years because of limited evidence and the absence of eyewitnesses. Advances in forensic techniques eventually yielded new leads and identified a suspect who had not been prominent in the initial inquiry.

Turner’s family sought answers throughout the long investigation. Does anyone have information about Turner’s circle in Clearwater around June 2014 that could help fill gaps in the timeline?
