WASILLA — Alaska authorities say an autopsy has determined a 74-year-old woman found dead outside her home died of natural causes and was not killed in a moose attack.

Alaska State Troopers said the body of Pattie Cucinello was found Sunday in the driveway of her Wasilla home.

Troopers’ spokeswoman Megan Peters said investigators had suspected a moose attack because there were moose tracks at the scene.

Peters said an autopsy by the state medical examiner’s office determined the woman died of natural causes and that the moose tracks were a coincidence.

Peters said post-mortem trauma was found on the woman’s body, but foul play is not suspected in the death. Peters declines to identify the specific cause of death.
