PITTSBURGH—Authorities in western Pennsylvania have identified a man stabbed to death by a resident during a home invasion in a Pittsburgh suburb.

The Allegheny County medical examiner's office said 21-year-old Devin Davis of the North Side neighborhood in Pittsburgh was the man killed during the 7:30 a.m. Wednesday home invasion in Penn Hills.

Police said three men entered the home through a garage and struggled with the homeowner. Investigators said Davis was stabbed and the homeowner pushed him out of the front door, where neighbors saw the body on the porch and called 911 while the homeowner and his wife fled for their own safety.

The other two men fled and remain at large. Police said no charges have been filed against the homeowner.
