A triple-murder suspect who was apprehended in Lewiston last week has been returned to Louisiana.

Robert McCoy proclaimed his innocence in the May 5 shooting deaths of his estranged wife’s son and parents as he was escorted to a maximum security facility in Bossier City, Louisiana, Wednesday.

McCoy flew out of Lewiston Wednesday morning, traveling under guard on a commercial airline, and arrived at Shreveport Regional Airport at around 5:30 p.m. local time.

McCoy, 34, was captured Friday night on Normal Hill while traveling as a passenger in a Swift Transportation truck. Lewiston police found a .380-caliber pistol behind the passenger seat of the truck, and Louisiana authorities believe the gun was used in the Bossier City murders.

Two Idaho charges of providing false information to authorities and having a concealed weapon during an arrest were dismissed earlier this week, clearing the way for McCoy’s extradition back to Louisiana.

Authorities there say he will remain on 24-hour surveillance after attempting suicide while being held at the Nez Perce County Jail.
