if it was a bloodstain, then BC would be locked up right now. Assuming her cause of death was blunt force trauma, which IIRC we haven't even seen a cause of death.
i'm not convinced that it is not a bloodstain.
it may be that the CPD are still building the case before making the arrest.
all brad said that is that she was going to take a run.
if the evidence supports an attack in the house, he'll say he was in another part of the house when the attack by a stranger occurred.
he will fit his alibi based on what the evidence reveals.
nancy could have been murdered at the house
and then subjected to another attack at the site where she was found. some wounds could be post mortem.
she may have been mortally wounded in the house and later died at the construction site. she may have been attacked further at the site where her body was found and it could have been staged.
i am interested in knowing at what point the car floor mat was put on the driveway.
was it put there by brad or the investigators?
what car did it come from - nancy's or brad?
was brad attempting to wash it off?
i'll try to look through the slideshow.
if something else catches my eye, i'll post it. you may have already talked about it.
