A convicted murderer who is an escapee from a Colorado prison was charged yesterday with attempted murder and armed robbery in the robbery of a store in downtown Bethesda Thursday and the stabbing of a police officer, Montgomery County police said.

David G. Phillip, 41, was in critical but stable condition yesterday at Suburban Hospital in Bethesda after being shot once in the abdomen Thursday.

Phillip escaped Aug. 19 from the minimum-security Skyline Correctional Center in Canyon City, Colo., according to Liz McDonough, spokeswoman for the Colorado Department of Corrections. Phillip also had escaped in 1976 by hanging onto the bottom of a trash truck.

Phillip had been serving a life term concurrent with a 34- to 40-year sentence in Colorado for the 1973 strangulation of an 83-year-old woman and the rape of a 54-year-old woman, McDonough said.

Montgomery County police charged Phillip yesterday with one count each of assault with intent to murder, assault with intent to maim and armed robbery.

The events leading to the shooting began shortly after 3 p.m. Thursday when Phillip allegedly robbed a 12-year-old store clerk at knifepoint in the 7500 block of Old Georgetown Road. After smashing a bottle over the clerk's head, Phillip ran away with a small amount of money, police said.

Motorcycle Officer Kevin Pugh saw Phillip at Elm Street and Wisconsin Avenue. Jackie Griffin, a production assistant at a Bethesda direct marketing firm, said she and a co-worker were walking beside Phillip when Pugh shouted to the suspect, "Stop, hold it!"

Griffin said she saw Pugh "pat down" Phillip, who knocked the officer to the ground. Police said Phillip also stabbed Pugh in the hand. While still on the ground, the officer fired several times at Phillip.

After being wounded, Phillip leaped into the back seat of a convertible, whose driver then slammed on the brakes. Seconds later, Pugh and another officer arrested Phillip.
