A smartwatch helped lead searchers to a plane crash that killed all three people aboard, Montana sheriff's officials reported. Dispatchers received a report of a missing airplane from the U.S. Department of Transportation Aero Division at 1:41 p.m. Friday, July 18, the Gallatin County Sheriff's Office said in a July 21 news release.

Authorities used the smartwatch’s last location to search for the small plane, which had three on board when it crashed “in dense timber” near West Yellowstone.

All three on board were found dead after the plane went down Friday after taking off from West Yellowstone Airport, authorities said.
