A woman died after being bitten in the head and throat by a pit bull that she and her sister were watching for a friend.

Jeannine Fusco, 44, was attacked Saturday in the garage of her home in Airmont, in Rockland County, police said.

"They were dog-sitting for an acquaintance, and she let the dog out early in the morning, and when it came back inside the animal went right after her," Ramapo police Detective Lt. Brad Weidel told The Journal News.

"She had severe bites to her throat and her head," Weidel said.

Fusco's sister, Valerie Wall, 43, was treated at Good Samaritan Hospital in Suffern for bites on a leg and a hand and was released.

Police said they found the pit bull in the sisters' backyard and killed it.

No charges had been filed against the dog's owner, but the investigation was continuing, Ramapo police Sgt. Mark Briggs said.
