What would you do if your friend came up to you and was like "help me dig this chick up so I can screw her".
I am confused.. so they couldn't remove the concrete vault to get to the corpse, yet still got charged with sexual assalt? And having sex with dead people = major loser.
Fixed I'm with you there. As they actually never got to the body, I would think the only charges that would stick, would be related to attempting to illegally exhume a body... maybe attempted sexual assault, but I guess it's all in how the law is written.
Sounds like someone took the phrase "Live Hard, Die Young, and Leave a Beautiful Corpse" a little too far.
The thing is, she died in a motorcycle accident. Given the circumstances of her death, I would think a normal person would assume it was a closed casket funeral and she probably got turned into hamburger. If you're gonna do it, look for a drowning victim, sheesh.
