“I dont remember a single teen mass killer back before they developed Frankenpot.”
I’m not up on dope, but I would imagine “Frankenpot” is a relatively new variant.
Would Charles Starkweather (1958, 19 years old, 11 victims) count?
Is that the only one? I guess it proves the point that now we have one of these psycho killers every month vs this one 60 years ago.
Ps it seems he had some birth defects that screwed him up
