COLUMBUS (AP) — Authorities say three people aboard a medical helicopter have died in a crash in southeastern Ohio.

A vice president of Survival Flight medical transportation says there were no patients aboard. Andrew Arthurs says the three who died were crew.

The Ohio State Highway Patrol says the company reported at around 7:20 a.m. Tuesday losing communication with a helicopter flying from the Mount Carmel Hospital in Grove City to pick up a patient in Pomeroy.

Authorities located wreckage nearly three hours later in rugged terrain near the community of Zaleski. That’s about 75 miles southeast of Columbus.

Federal Aviation Administration spokesman Tony Molinaro in Chicago says the helicopter was a Bell 407. Molinaro says the FAA and National Transportation Safety Board will have investigators at the scene.
