CASPER, Wyo. (AP) — Relatives of a Wyoming soldier who was killed in a suicide attack in Afghanistan remember him as a man who was dedicated to the military and to his family.

The Defense Department said Thursday that 45-year-old Army Command Sgt. Maj. Kevin J. Griffin, who grew up in Riverton, was killed Wednesday.

Dustin Griffin, the soldier's nephew, told the Associated Press  his uncle "was definitely 100 percent Army."

Meanwhile, Shawn Griffin said his brother "loved the Army, but on top of that, he loved his family."

The attack also killed 35-year-old Army Maj. Thomas E. Kennedy, of West Point, N.Y.; 38-year-old Air Force Maj. Walter D. Gray, of Conyers, Ga.; and USAID foreign service officer Ragaei Abdelfattah.

All three troops were based at Fort Carson in Colorado.
