LARGO — A judge ruled Wednesday that Stephen Coffeen "did not understand the wrongfulness of his actions" when he smothered his father to death in St. Petersburg and therefore is not guilty by reason of insanity.
It was dubbed the "Red Bull defense" case because one expert mentioned in a court hearing that Stephen Coffeen, 41, suffered from sleep deprivation and had been drinking a lot of the Red Bull energy drink.
