A triple-murder suspect captured in Lewiston has been cleared to be extradited back to Louisiana, but he must first face two misdemeanor counts in Idaho.

A pretrial hearing is set for Tuesday morning in Lewiston’s 2nd District Court for Robert McCoy on charges of giving authorities false information and having a concealed weapon during his arrest.

McCoy, 34, is the prime suspect in the slayings of his estranged wife’s 17-year-old son and her parents Monday night in Bossier City, Louisiana. He was caught while traveling as a passenger in a Swift Transportation truck in the Normal Hill area Friday night. Authorities say he eluded authorities for nearly four days by fleeing to Texas, Arkansas and Washington, traveling as a passenger in 18-wheelers.

McCoy was taken into custody without incident, while the truck driver was not charged. A .380-caliber pistol was retrieved from behind the passenger seat of the truck, and Louisiana authorities believe the gun was used in the Bossier City murders.

McCoy was booked into the Nez Perce County Jail on three murder warrants and may face a charge of unlawful flight to avoid prosecution.
