A 24-year-old man was arrested without incident on Thursday in connection with a Monday robbery in Spokane Valley involving a carjacking and kidnapping of an elderly couple at a Wal-Mart store. Blaine Allen Cornwell was taken into custody by U.S. marshals and members of a violent crime task force while in the 5700 block of North Elm Street as he and another person were getting into a vehicle about 5 p.m., according to the U.S. Marshals Service. The second person was also taken into custody, but not booked into jail, authorities said.
