Sidney J. Campbell, 56, was found dead on February 23, 2017, in a home on Whitethorne Avenue in the Hilltop neighborhood of Columbus, Ohio. Paramedics were called for a report of someone not breathing; they pronounced Campbell and a second victim, 31-year-old Marie E. Stamp, dead at the scene.

Investigators say Campbell and Stamp were killed in connection with a drug trafficking operation that was using the victims’ home to store and sell illegal drugs. Two men, Antwan L. Hutchinson and Michael J. Favors, were identified in the investigation; the indictment alleged conspiracy to distribute and possess controlled substances and murder of a witness, and Hutchinson admitted to killing both victims to prevent them from testifying against him.

Anyone who knew Sidney Campbell, Marie Stamp, or who has information about activity at the Whitethorne Avenue residence in February 2017 is asked to come forward.
