Mohamadou Diallo, 25, was found unresponsive on the Southeast Side of Columbus after officers responded at 2:12 p.m. on June 25, 2025 to a reported robbery in the 4400 block of Coble Hill Drive near Canal Winchester. He was located a short distance away in the 5400 block of Coble Square Place, taken to a nearby hospital, and pronounced dead at 3:12 p.m. The scene covered a quiet suburban street and a neighboring cul-de-sac; detectives worked into the afternoon and noted several people were detained and cooperated as they reconstructed how the robbery call related to Diallo’s collapse.

By nightfall next of kin had been notified and the case was classified as a homicide. Authorities have not publicly identified a suspect and no arrest had been announced; the homicide unit asked anyone with information to contact Detective Journey or the Homicide Unit. Memorial listings later recorded Diallo’s name, date and city of death but offered no details about those responsible. If anyone was in the area that afternoon or saw people leaving the scene, what did you notice?
