One man is dead and another wounded after what appears to be a burglary in Overbrook, police said.

Just before 10 p.m., police found a 22-year-old man shot in the leg on the roof of a home on Wyndale Avenue near 58th Street, Chief Inspector Scott Small said.

He was taken to the Hospital of the University of Pennsylvania in stable condition, where he remains tonight.

But he wasn't the only victim.

In a bedroom on the home's second floor, police found a man in his late 20s shot once in the head. He was pronounced dead at the scene.

Initial evidence from the scene, including information provided by the homeowner's 26-year-old girlfriend, indicates that the two residents came home to a burglary in progress, with at least four masked men inside the residence, Small said.

Two semiautomatic handguns and six spent shell casings were recovered inside the home, but it's not clear who fired the shots that wounded the two victims.

There were also signs of forced entry in the home: A first floor window was smashed, apparently by the burglars, as was a second floor window, apparently by the homeowner during his escape onto the roof.

The only thing taken during the incident was the 26-year-old woman's cellphone, which police have been unable to trace, Small said.

That woman is currently being interviewed by detectives from the Homicide Unit.

"This is normally a nice, quiet, peaceful neighborhood," Small said. "But there have been some burglaries in the area in the past."

Police are continuing to investigate the shooting.
