A massive Clavert County hunt for a man wanted since Friday in the shooting death of a bartender and the injuring of two other people was called off last night, after it appeared the man had escaped, Maryland state police said.

The unidentified suspect had been sought by 90 men using bloodhounds and helicopters in a heavily wooded four-square mile area near the town of Prince Frederick, about 45 miles from Washington, according to First Sgt. Richard Stufft of the state police.

The man has been sought since the shooting death Friday of John Bishop, 45, a bartender at the Knotty Pine Bar & Grill, on Rtes. 2 and 4, in Lusby, in Calvert County, Stufft said.

According to police, three men robbed the bar about 1:30 p.m. Bishop was killed, Viola Foote, 55, an owner of the bar, was pistol-whipped, and her husband, Burton Foote, 61, both of Lusby, was shot in the mouth. Two unidentified customers were bound and gagged, but were not injured, police said. Burton Foote is in satisfactory condition at Calvert Memorial Hospital, Stufft said.

Walter West, 24, of Landover, and Tony Mitchell, 26, of the District, were arrested shortly after the shooting and each charged with homicide and armed robbery, Stufft said. They are being held pending a further investigation, police said.
