Maybe some wounds occurred at abduction & others at cornfield. He had to disable her to a degree to get her into that trunk. If conscious, I’d think she’d have tried to escape. Don’t recall year of Malibu, but the glow-in-the-dark trunk releases were installed after a certain year. So guessing she wasn’t conscious? IdkA wound on the back of her hand...she tried to fight him off.
I am convinced he raped and murdered her in the cornfield. There would have been so much more blood found in the trunk if killed prior.
