Authorities say one person is dead and two are injured after an EagleMed medical helicopter crashed in woods in eastern Oklahoma.

McIntosh County Emergency Management Director Wesley Dawson says the crash was reported about 11:40 p.m. Thursday. Dawson says searchers on foot and on all-terrain vehicles found the wreckage about 4 a.m. Friday.

The crash site is west of Eufaula, about 120 miles east of Oklahoma City.

EagleMed, of Wichita, Kansas, said in a statement that all three on board the helicopter were EagleMed employees. No names or the conditions of the survivors have been released.

A Federal Aviation Administration spokesman says agency investigators are being sent to the scene and that the National Transportation Safety Board will lead the investigation.
