Charlie Ferguson, 58, was shot and killed outside his Detroit home on the evening of July 22, 2016. Officers responded after reports of gunfire and found Ferguson suffering from gunshot wounds; he died despite emergency efforts.

Detroit Police Department detectives opened a homicide investigation and canvassed the neighborhood for witnesses and evidence, but preliminary reports did not identify a motive and no suspect or arrest was publicly named in the days after the shooting. The case was listed among the city’s unsolved homicides for that year, and family and community members were left seeking answers.

Does anyone who lived in that neighborhood or who knew Charlie have information that could help investigators?
