(CBS) Law enforcement officials believe the sniper who has terrorized the Washington D.C. area is still at large, CBS News Correspondent Jim Stewart reports.
Stewart said the officials "feel confident" that neither of two men being questioned in connection with the shootings is the sniper. The men in custody after the seizure of a Plymouth van at a gas station in Richmond, Va., Monday are believed to have made a call to a phone number connected to the sniper case, but they are not thought to be the perpetrators.
Stewart reports that some law enforcement officials speculated that the men may have been involved in some type of extortion scheme related to the sniper murders or some other kind of hoax.
