A couple was found bloodied and beaten in a South Philadelphia rowhouse late Sunday night, police said.

A relative who lives in the same apartment building on the 1300 block of Federal Street found the the two victims - a 23-year-old woman and 50-year-old man - in separate rooms of their first-floor apartment, police said.

The relative was later identified as the 50-year-old's mother. A cousin told NBC10 his name was Candido Gonzalez, a single father who was raising a son. He lost his brother several years ago in the same building.

Gonzalez and his girlfriend had bruises on their faces and lay in pools of blood when they were found, police said. The apartment was ransacked but there were no signs of forced entry.

"I don't understand. I've been living on this block for 35 years and nothing like this has ever happened," said neighbor Angela Arico. "I'm at a loss for words."

Both victims were pronounced dead at the scene.
