Sergeant Dwight W. Burn, 27, of Barstow, California, died from injuries sustained when a CH-47 Chinook helicopter crashed in Fort Bliss' northern training area near Orogrande, New Mexico, about 45 mi. (75 km.) northeast of the post.

The three other soldiers were stable and two were expected to be released from a hospital soon, the officials said.

A cause of the crash has yet to be determined. The soldiers were from the 82nd Airborne Division based at Fort Bragg in North Carolina.
