HOLLIS, Alaska (AP) — A 63-year-old man found dead under an all-terrain vehicle had been attempting to load the machine into a pickup.

Charles Lundin was found Saturday underneath a four-wheeler in Hollis on Prince of Wales Island about 35 miles (56 kilometers) west of Ketchikan.

Alaska State Troopers shortly after 8 a.m. Saturday received a call asking for a check on Lundin. They found him under the ATV.

Trooper spokesman Tim DeSpain in an email said Lundin was house-sitting at the home where he died.

Investigators believe Lundin attempted to drive the four-wheeler into the back of a pick-up using a ramp with a steep angle.

The ATV apparently flipped, trapping Lundin beneath the machine.

The state medical examiner will conduct an autopsy to determine cause of death.
