Here is the biggest outright study done on it. Though if you search up serial killers and head trauma you can find a lot of talk about it because if you go down a list of all the "popular" ones you will end up checking off "major childhood head injury" on most all of them.
The study found 1/5 for it, that's a pretty significant common element to find considering the otherwise diversity found in the group. And, if I can insert my personal opinion, I'd wager that if you narrowed it down to what people think of when you say "serial killer" (A Bundy for example) and removed the random crime/gang killers who just got a high score it would likely be a lot higher.
Though I hadn't seen the study had also linked autism at a much higher rate which is interesting. But considering the study was being done right as the DSM-5 was coming out, which gutted Autism as a diagnosis and made it far stricter to diagnose, I also put less weight into it.
No, I mean where did you hear the head-injury thing being associated with serial killers?
I'm over 40 and I've NEVER heard this.
