Just as guilty here is the 13-yo girl...13 by age. This could have been her first attempted encounter or one in a long line. No way to know. 13-yo could be she was 12 last week or 14 next week.
She wanted what she wanted, resulting in one dead rapist or would-be rapist and one likely convicted killer mother. And the kids? Idk, go to relatives or foster care, I guess.
I’m from Memphis and no way this guy didn’t know she was young. She looks like a 13 year old. If you go into any young girls room, it will be obvious she is younfg with the stuffed animals on the bed and other thing young.
