you are correct - they were coming home from “Knott’s Scary Farm” at Knott’s. It’s the Halloween haunt/scare fest and closes at 2:00 a.m.
I live 5 miles from the scene, and wouldn’t be surprised if my kids know some of them.
My kids go there every year.
God knows young people don’t drive as smart as more experienced people, and when I was younger I escaped problems due to good luck.
Nothing to be said but prayers. Anything else is callous.
