Authorities are investigating whether a Staten Island woman may have been mauled to death by one of her four dogs, police sources said.

Daisie Bradshaw, 68, was found dead in the basement of her Simonson Avenue home in Mariner’s Harbor with bite marks, cuts and bruises all over her body on Tuesday.

The woman’s daughter made the discovery when she walked into the home at around 9:40 a.m. and found her mom’s chewed body.

Two of the dogs roaming through the house while two others were locked in a bathroom, sources said.

The medical examiner’s office has yet to determine the official cause of death. It wasn’t immediately clear what kind of dogs the woman owned.
