John Leavells, a man from Detroit, Michigan, was killed in 2013 in what has been described as a homicide.

The case appears to have gone cold. Reporting notes that Detroit’s police force faced resource limits in 2013 and that community distrust and fear may have discouraged witnesses from coming forward, but specific investigative details, timelines, or information about Leavells’ life and final days have not been released.

Anyone who knew John Leavells or has information about his death is asked to come forward to help fill in the gaps.
