Officers say Lee Vanover asked a family to use their phone and when he went inside their house, he started robbing the family. Vanover attacked a man there with a pocket knife, cutting and bruising him. Vanover then ran from the scene but was later apprehended with only a cell phone. Officers said the cause of the robbery was clearly drugs. He was lodged in the Knox County Detention Center.
