An 18-year-old man was arrested early Wednesday during a home invasion in Philadelphia's Fern Rock section that left two of his neighbors, including a 71-year-old woman, in critical condition with numerous stab wounds, police said.
Anthony Waters of the 5900 block of North Fourth Street stabbed the 71-year-old woman about 20 times and a 54-year-old man several times after Waters entered their home about 4:45 a.m., police said.
The rear door was unlocked, police said, and the assailant attacked the two after he was surprised to find them inside the home.
Responding to a report of a stabbing and burglary, police officers found the woman lying outside her front door. They also found Waters standing near the woman.
