Richard Harder, 45, was found dead in his Detroit east side home on the evening of December 17, 2018. The discovery came at about 10 p.m., and investigators determined he had been fatally shot in the back of the head in what was described as an execution-style killing.

Investigators continued the probe through 2019 but no suspects were publicly identified and no arrests were announced. In March 2019 Crime Stoppers of Michigan offered a cash reward of up to $2,500 for information leading to an arrest. Despite that appeal, the case has gone cold and remains unsolved.

Are there any neighbors, acquaintances, or others who remember unusual activity around that east side home in December 2018?
