EDWARDS AIR FORCE BASE, Calif. (AP) _ An Air Force airman fatally shot two fellow servicemen Saturday and then committed suicide at this desert base, authorities said.

Senior Airman DeVaughn L. Brown, 23, of Lawton, Okla., killed a senior airman and a military police officer, then fled to his dormitory and apparently shot himself to death. Brown, stationed at the base for 3 1/2 years, was found shortly before 7 a.m.

Senior Airman Darrick F. Moore, 27, was found shot to death at the landfill on this remote desert base 120 miles north of downtown Los Angeles. Moore, who was married and from Wahiawa, Hawaii, had been stationed at Edwards for 3 1/2 years, authorities said.

There was no immediate word on the motive for his killing.

Brown and Moore were last seen together at Stripes, a bar on base, late Friday night, according to Col. Ed DeIulio.

It was unclear whether they were drinking or if they had argued, DeIulio said.

Base officials said Brown shot Moore sometime before 2 a.m., then drove off in his car.

A short time later, he gunned down Tech. Sgt. Robert Butler after the veteran security officer stopped the car, said George Fox, a spokesman for the base 120 miles north of downtown Los Angeles.

Butler, 34, was with the 95th Security Forces Squadron and was a 13-year Air Force veteran.

``He was a good man, a regular churchgoer,'' Butler's father, Joseph Butler, said in a choked voice during a telephone interview from Philadelphia.

``From what I was told so far, my son had made a stop for a DUI (drunken driving) investigation at two in the morning, and this guy shot him in the face and killed him.''
