CLEVELAND, Ohio -- One of two men killed in a triple shooting Friday morning had turned a gun on himself, Cleveland police said.

The violence erupted about 10:45 a.m. in the area of East 84th Street and Cedar Avenue.

Police cordoned off two crime scenes including a home on East 84th Street where a man in his 50s was found shot dead, and a silver Ford Mustang parked behind the home on East 85th Street where another man killed himself.

A third man, also believed to be in his 50s, was driven to MetroHealth Medical Center in critical condition after being shot in the chest at the home, police spokesman Sgt. Ali Pillow said.

The identities of the three victims have not been released. Investigators have not determined a motive but are looking into whether the gunfire stemmed from a robbery.

A police supervisor called to the scene for a report of a shooting saw a man running opposite his direction from East 84th Street. The officer followed the man to East 85th Street, where the man got in the driver's seat of a Mustang, Pillow said.

The officer ordered the man to raise his hands. The man pulled out a handgun and shot himself, Pillow said. Investigators found several weapons inside the car.

The Cuyahoga County Medical Examiner's Office will identify the victims.
