A third arrest has been made in connection with the Audrain County homicide investigation. Boone County sheriff’s deputies Tuesday morning arrested Justin Traughber as he walked along Mulberry Drive in Columbia. Deputies say they found meth and drug paraphernalia on Traughber. Authorities believe Traughber is the other man seen on camera forcing Leon Wilder into a pick up truck on the morning of July 6th at a Columbia motel. Wilder was found later that day, dying in a ditch along County 997 near the Boone County line with a gunshot wound to the head. Two St. Louis County residents are held in Audrain County jail on murder charges. Traughber for now faces drug and firearms charges in Boone County.
