The father of Spokane bomb suspect Kevin W. Harpham was injured today in a motorcycle accident in Cusick, Wash. Cecil W. Harpham, 68, of Kettle Falls, was riding a 2000 Harley-Davidson motorcycle south on Highway 20. At about 1:15 p.m., on a curve to the right, he drifted off the roadway, entered a ditch and was partly thrown from the bike, according to the Washington State Patrol. He was transported by MedStar to Providence Sacred Heart Medical Center, where he was in critical condition this evening, according to a nursing supervisor. He was wearing a helmet at the time of the crash, WSP reported. Harpham’s son, Kevin, 37, was arrested March 9 in connection with a backpack bomb discovered along the route of Jan. 17’s Martin Luther King Jr. Day Unity March. Kevin Harpham is lodged at the Spokane County Jail and faces charges of attempting to use a weapon of mass destruction and possession of an unregistered destructive device. His trial is scheduled to begin Aug. 22. Cecil Harpham originally said his son was with him on Jan. 17, but has since reportedly recanted that alibi.
