Dwaine Alexander, a 29-year-old African American man, was found shot to death behind a residence in Detroit on Sunday, September 17, 2017. Police were called to the scene and opened an investigation, but immediate reports offered few details about motive or what led to the shooting.

Investigators have faced a shortage of cooperating witnesses and definitive leads, and the case was recorded among the city’s unsolved violent crimes. No suspects or arrests have been publicly identified, and Alexander’s name has appeared on lists used by crime-solving organizations to solicit tips.

The case remains open and unsolved. Does anyone who lived in that Detroit neighborhood in September 2017 remember anything that could help investigators?
