An Army safety board from Fort Rucker, Ala., is probing the cause of an accident that claimed the life of a parachute instructor during a night training mission Friday at Dugway Proving Ground.

Master Sgt. Donnie Shocklee, 34, was one of the instructors for Ranger training at Dugway. For the past two years, he lived on base at Dugway with his wife, Kathy, and their two sons, Donnie and Russ, and daughter, Cristin.Shocklee's body was discovered Saturday morning after an all-night search with helicopters. He died upon impact of massive head and neck injuries.

He was the senior non-commissioned officer for the 7th Ranger Training Battalion at Dugway for the past two years, and had 900 jumps to his credit. He was an instructor in a nighttime mass parachuting exercise.

When he was found, "the chute was open and everything seemed to be working," said Carol Fruik, public affairs specialist for Dugway.

A memorial service was planned for Wednesday at Dugway and Shocklee's funeral was to be held Thursday in Palm Dale, Calif., where his parents live.

The routine parachute training jump took place at 9:45 p.m. Friday over Dugway's Remote Training Area.

When Shocklee did not appear at the assembly point within 45 minutes for the tally that takes place after parachute jumps, a ground search was launched.

He was flown to University Medical Center, where he was pronounced dead at 12:05 p.m. Saturday.
