A man who drove his rental car to an overlook at Grand Canyon and plunged hundreds of feet off a cliff was identified on Sunday.

He was Mihaly Szabo, 44, of Ypsilanti, Mich., park spokeswoman Maureen Oltrogge told The Associated Press.

Rangers were trying to determine how Szabo ended up 300 feet below the south rim of the Grand Canyon near a picnic area, where snow and ice covers the ground, Oltrogge said.

A helicopter crew recovered Szabo's body with a winch on Saturday.

His unattended rental car was first spotted at the Buggeln picnic area on Wednesday, and by Friday a search turned up a chair, camera and other items of Szabo's at a nearby view point.

Autopsy results were pending on Sunday, said Oltrogge, who didn't have any other information about Szabo or his travel plans.
