Investigators are building a federal racketeering case against Chevie Kehoe and his associates for alleged involvement in crimes in several states.
The crimes include attempted murders of police in Ohio, killings in Idaho and Arkansas, a kidnapping-extortion in Colville, Wash., and the theft of weapons.
Three witnesses from Spokane, including Kehoe's brother, Cheyne Kehoe, recently testified in secret before a federal grand jury in Little Rock, Ark.
