A lot of suicides are poorly planned, and Carl's is one of them. Based on actual crime scene photos of suicide attempts in which the subject places a rifle or shotgun under their chin and pulls the trigger, intending to blow their brains out. Unfortunately (fortunately?) due to the length of such a gun, and the length of a persons arms, the shot angle is usually too shallow and blows off the victims face instead. Such horrific wounds are often survivable.
