GRAND JUNCTION, Colo.—Colorado National Monument officials planned to use a crane to remove a van teetering on a rock outcropping at the Western Colorado landmark.

The 260-ton crane was expected to pluck the van off the rock Thursday.

Authorities say 34-year-old Daniel John Lyons of Clifton drove the van about 120 feet off Rim Rock Drive in an apparent suicide attempt Jan. 21. He called 911 when the van got hung up on the rock.

It took two hours for emergency crews to stabilize the van and rescue Lyons. He was taken to a hospital, then released Saturday and booked into the Mesa County jail on suspicion of felonies including sexual assault on a child.

It wasn’t clear if Lyons had an attorney. The jail did not immediately return a call.
