IDAHO FALLS, Idaho (AP) — Idaho Falls fire officials say a worker from Utah tending to an air-conditioning unit on the roof of Mountain View Hospital died after being electrocuted.

Idaho Falls Fire Department Capt. Brett Johnson says the accident occurred Tuesday night. The man's name has not been made public pending notification of family.

Johnson says the man was employed by a Utah company contracted to perform maintenance at the hospital.

Investigators are still trying to determine how the accident occurred.

Mountain View spokesman Joshua Tolman says details are a bit sketchy this early in the investigation.
