A former Oklahoma teacher was arrested in the killings of a married couple at Devil’s Den State Park, with two school districts confirming he previously worked in their classrooms.

The suspect who is accused of killing a married couple who were hiking with their children at Devil's Den State Park in Arkansas was a teacher in Flower Mound, according to an Associated Press report.

A parent claimed their child was in James Andrew McGann's class while he was employed as a teacher at Donald Elementary in Lewisville, Texas, and he was reported for inappropriate conduct towards little girls.
