On the evening of December 4, 2012, 16-year-old Shawn Bender, a Black male, was found dead inside a residence on the 15000 block of Tacoma near Brock Avenue in Detroit. The body was discovered at about 9:15 p.m. in a modest east-side home. Shawn was one of four people killed there; the other victims were 34-year-old Dyrelle Davis, 22-year-old Janetta Harris, and 28-year-old Jason Koester. Each victim had been shot in the head, and investigators described the scene as an execution-style shooting.

The house was discovered by Koester’s girlfriend after she stepped out briefly to get food. Early reports mentioned a theory that the attackers may have posed as police to gain entry, but that detail was not confirmed. No arrests have been announced and the motive remains unknown.

Does anyone have information about that night or knew the victims who can help investigators?
