They've found bloody in the hire car...yes...but the parents have sedated her so that she stayed asleep in the hotel room, got back to the hotel room, realized that they have od'd her from to much sedation...panicked and thought "Shit, we'l loose our jobs, loose the kids...we need to get rid of the body". So they let the case quiten down abit. Hide the body in some way for 5 weeks or however long it is...Rent a hire car and dispose of the body...But still...They have only sedated her...Why would that leave Maddy's blood in the car ? Beyond me. Danny.
