Police say a 33-year-old man is dead after he was shot breaking into his ex-girlfriend's west Philadelphia home.

WPVI-TV reported the woman and her new boyfriend heard her ex breaking in early Wednesday. They managed to push the man back from entering a first-floor window, but police say the man was able to break in through a second-floor window.

Lt. John Walker says the man started fighting with them and at some point a gun was pulled and a shot was fired. It's unclear who pulled the gun or fired the shot. The ex-boyfriend was found shot in the chest and later died.

The new boyfriend fled the scene.

Police say the woman's two boys, whose father is the ex-boyfriend, were also home.

No names have been released.
