Chitwood says the man confronted the ex-girlfriend on the porch of her parents' home in Upper Darby, five miles west of Philadelphia. She ran in and locked the door, but he broke in.
Chitwood says the two struggled in the living room and "continued upstairs into the bathroom, where she was stabbed and found dead on the floor." He says the woman's little sister hid in a closet and heard the struggle. Police say the man faces murder and other charges.
