The accident occurred about a half mile south of the James Creek Road while Baldwin was recreating in the Rocky Bar area with family. A member of his family had been following him but had fallen behind and did not witness the accident. The ATV was spotted in the ravine by a passerby who reported it to the Elmore County Sheriff's Office at about 3 p.m. The body was recovered by sheriff's deputies and LifeFlight personnel.
Baldwin was a volunteer EMT in the Pine area and also a fireman in Boise.
Deputy Fred Peterson, who investigated the accident, said there was no indication alcohol was involved. Rather, he said, "it appears he just missed the curve."
