The Cuyahoga County Medical Examiner’s Office on Wednesday identified two of the victims from fingerprints as 20-year-old Dejuan Willis, of Cleveland, and 23-year-old Christopher Monroe, of Cleveland.

The bodies were discovered Saturday in a bedroom on the third floor of the boarded-up home. reports a Cleveland city councilman said residents found the bodies during a neighborhood cleanup.

Police found a gun inside the home and said it was known for drug activity.
