Officer John Schemm died as the result of injuries sustained in a fall down a set of stairs at 4201-4203 Murray Avenue. Patrolman Schemm was assigned to night time patrol in the Squirrel Hill section of Pittsburgh. A doctor who was opening his office in the building found Officer Schemm laying at the foot of the stairs. The building owners regularly left the front door open so patrolmen could check the interior.
Patrolman Schemm was appointed to the Pittsburgh Police Department on April 1, 1921. He was survived by his wife Anna Ruthling Schemm.
