On the evening of December 4, 2012, 22-year-old Janetta Harris was one of four people found shot to death inside a home on Tacoma Street on Detroit’s east side. The other victims were Jason Koester, 28; Dyrelle Davis, 34; and 16-year-old Shawn Bender. The bodies were discovered about 9:15 p.m. when Koester’s girlfriend returned to the house after going out for food.

Investigators described the scene as brutal and used the term execution-style; the three male victims were each shot in the head, while the Wayne County medical examiner ruled Harris’s cause of death as multiple gunshot wounds. Police said they believed the killings were drug-related, and neighbors had described the residence as a dope house. A suspicious fire damaged the home the next day and was believed to have been set intentionally.

The motive was never confirmed and the probe grew cold. A partially redacted report shows a student was taken in for questioning after a tip about statements of complicity, but no arrests or charges were announced. Does anyone have information that could help bring answers for Janetta Harris and the other victims?
