Four people are dead after a small plane crash, the San Juan County Sheriff’s Office said Friday.

The single-engine plane, a Piper Lance, had been flying from Grand Junction, Colo., to Albuquerque, N.M., according to FAA spokesman Lynn Lunsford. It was reported missing late Thursday.

The wreckage was found about 18 miles southeast of Monticello, Lunsford wrote in an email to The Salt Lake Tribune. Search crews found the plane at about 5 p.m. on Friday, according to a Facebook post from the San Juan County Sheriff’s Office.

All four of the plane’s occupants died, according to San Juan County dispatch.

Civil Air Patrol and Colorado agencies assisted in searching for the downed plane, and the National Transportation Safety Board will investigate the crash.
