The would-be robbers who shot and wounded off-duty Police Officer Martin P. Campbell and killed his friend in Hunting Park last night are still at large, investigators said this afternoon.

Homicide Capt. James Clark said a $5,000 reward has been posted for information leading to their capture.

After last night's shooting, police looking for the assailants shot one man who pulled on a gun and captured another. Clark said they were not the men involved in the attack on Campbell and two friends, one of whom, Rasheen Allen, was killed.

Campbell, 23, a patrol officer in the 5th District who was shot in the leg, is in stable condition at Temple University Hospital. Allen, 30, the officer's longtime friend, was shot once in the head and pronounced dead on the scene.

Police said the men being sought wore dark clothes and hooded sweatshirts, and that one was short, about 5 feet 1 or 5 feet 2 inches tall, and appeared to be in his late teens or early 20s. The other was taller, about 5 feet 9 inches, and looked to be in his early to mid-20s.

Campbell, Allen and the third friend were talking outside on the 4400 block of Marshall Street, where Campbell and Allen grew up and where Campbell's parents still live, last night around 7:30 p.m. when the two men approached and announced a robbery, Clark said. The taller man put his gun to Allen's head.

"At that point, he tries to push it away," Clark said. "And shots rang out."

The gunman fired three times, striking Allen in the head at close range, and Campbell in the leg.

The third person with Campbell and Allen was uninjured. The bandits fled with nothing, Clark said.
