A hiker found on a ledge 150 feet below the summit of a massive rock pillar in Zion National Park was identified Tuesday as a Sandpoint, Idaho, man, Washington County Sheriff's deputies said.

The victim was identified as Jeffery Robert Dwyer, 28. But the cause of his death late Saturday or early Sunday was still under investigation."There's enough suspicion because of the amount of blood we found that we've ruled it a suspicious death," said park spokesman Bob Andrew.

Dwyer was traveling with two other people on a seven-week trip through the western United States and Mexico, Andrew said. He was last seen alive on Saturday.

Tourists found a blood-stained backpack and a pool of blood Sunday on the top of Angel's Landing, a 1,500-foot-high sandstone column. A helicopter pilot spotted the body about 4:15 p.m. Sunday on the ledge, but climbers were unable to recover the body until 11 a.m. Monday.

"There's a lot of injury to the head," Andrew said, "but what we're concerned about is all the blood on the top of Angel's Landing. We're awaiting the autopsy to determine the cause of death. Right now we're just calling it a fatality."

The incident also was being investigated by the FBI, which has jurisdiction in deaths in national parks.
