Frederick D. Campbell, 36, was found dead in Detroit on May 26, 2015. His most recent sentence ended November 6, 2014, a little over six months before he was discovered.

Detroit police have not publicly identified any persons of interest or made arrests in connection with Campbell’s death, and official statements have been limited. With few investigative details released and no named suspects, the circumstances of how and why Frederick Campbell died remain unresolved.

If anyone knew Frederick, saw him in Detroit in May 2015, or has information that could help, please come forward.
