YORK, Pa. (AP) _ Investigators searching a creek for the rifle used in the 1969 murder of a York police officer during a race riot found no trace of the weapon, but they did discover four other guns.

A dozen specialists equipped with wet suits, scuba gear and metal detectors spent several hours Saturday scouring the bed of Codorus Creek for evidence in the July 18, 1969, slaying of Officer Henry C. Schaad.

Instead of the rifle used in his slaying, the team pulled up a revolver, an old-fashioned flintlock pistol, a double-barreled shotgun and a pellet gun. Investigators had not determined if the flintlock was a modern replica or an antique.

Two black men _ Stephen Freeland, 49, and Leon ``Smickle'' Wright, 53 _ face murder charges in the shooting of the white police officer, which occurred on the second night of riots touched off by the wounding of a black teen-ager by a white gang member.

Three days later, a black woman, Lillie Belle Allen, was killed by a white mob. Nine men, including Mayor Charlie Robertson, who was a police officer at the time, were charged earlier this year with her murder.

District Attorney H. Stanley Rebert said investigators learned from secondhand sources that the weapon might be in the creek. ``We figured, why not take a shot at it?''

A judge said last week he won't rule until at least next month on whether charges against the nine white men accused of killing the black woman during the riot should be dismissed.

Defense attorneys say too much time has passed since the slaying to guarantee their clients a fair trial.
