An Oklahoma teenager was shot to death, one suspect is behind bars and another is on the loose. Christyan Boswell, 18, of Valliant, was fatally shot Saturday at the intersection of Wilbur and Mosley Streets. Cody Hilderbrand, 20, was arrested and a manslaughter warrant has been issued for a second suspect, 37-year-old Justin Luther. Investigators believe Hilderbrand killed Boswell after a drug deal went bad.
