A senior at Northeast High School in Clarksville, Tenn. has been suspended for 10 days and faces a multitude of additional punishments including criminal charges because school officials found a knife belonging to his father inside his father’s car. The student is David Duren-Sanner, reports local CBS affiliate WTVF. The student’s father is a commercial fisherman who works on the West Coast. The father left — wait for it — a fishing knife in the car. Duren-Sanner has sworn he knew nothing about it.
