PHILADELPHIA (CBS) — A West Philadelphia woman is fighting for her life after being shot inside her apartment. It happened after her roommate was sexually assaulted. Now, police need help identifying a person of interest.

“I think you should be worried, yeah,” said Philadelphia Police Capt. Mark Burgmann.

Philadelphia police are searching for a man who they say, within the span of an hour early Sunday, broke into cars, broke into a home, raped a woman and then shot another.

“I think, quite frankly, he was trying to get into vehicles, get anything he could, and I think he forced his way inside the property, pushed the door open and was able to get inside,” Capt. Burgmann said.

Officers were called to the 7400 block of Brockton Road, where they found a 23-year-old woman had been shot. The woman, authorities say, confronted an intruder as he assaulted and raped her 21-year-old roommate.

“Told him to take what he wanted and leave. At that point, she was shot in the abdomen,” Burgmann said.

She was rushed to the hospital in critical condition. The offender then fled the residence but police say he left plenty of evidence behind.

“If you look very closely, you will see this man is armed with a handgun on the left side of his pants,” Burgmann said.

Nearby surveillance cameras caught a man matching the suspect description casing and breaking into multiple cars immediately before the attack.

Investigators say the man did not know his two victims and may have been lured into the home by nothing more than a faulty lock.

Police advise that everyone in the Overbrook Park area and beyond should make sure that their doors and windows are fully secured.

Police say the suspect is considered armed and very dangerous.

Anyone with information about this incident is asked to call police at 215-685-3252/3264.
