On December 4, 2012, a home on Tacoma Street in Detroit was the scene of an execution-style quadruple slaying. Four people were found shot to death inside: 28-year-old Jason Koester, Dyrelle Davis, 34, Janetta Harris, 22, and 16-year-old Shawn Bender. Jason Koester, a short-order cook from St. Clair Shores, had been staying at the house about a week to be with his girlfriend and his father said Jason had been planning to marry that same month.

Investigators followed at least one tip that led to a student being taken into custody as a person of interest after allegedly making statements about involvement, but no charges were publicly announced and police reports gave no further connection. A year after the killings the police chief acknowledged the initial detective on the case was new to homicide. The Wayne County Prosecutor’s Office confirmed in early 2014 it had not received a warrant request from Detroit police.

No arrests have been announced and the case remains unsolved. If anyone knew Jason, the others killed that night, or has information about the Tacoma Street murders, please come forward.
