I keep wondering, why even bring Mr Dermond's body into the garage if that wasn't the crime scene? I'm just not convinced that it wasn't within the home, or in the garage. I know blood splatter would be present if it's an open wound to the head, but, there's close wounds as well that cause such brain damage it kills the person. And if a drain was in the garage, or a utility sink area, well, bleach and lots of water down the drain. Same thing if it was in the bathtub or shower.
I know I read where dogs were brought in, and they should have hit on any blood on the property IF they were allowed to walk every inch of it. If the bodies had been drug on a tarp, or sheet, the dogs still should have hit on that. And maybe they did, but we haven't been told.
I don't know, but I would guess they would have to have an article from the suspect for the dogs to track their path to the lake or whatever.
Really OFFTOPIC SKIP IF YOU WANT!
I have some orphan piglets right now. I keep trying to introduce them to the sow in hopes she will accept them. BUT, as of today, I realize they are imprinted on me, and my scent, and voice. I took them outside and put them in the pig lot near their Mom today, and walked away out of the Mom's sight, in hopes she would hear them squeal and realize they were hers. Those tiny little piglets instead put their nose to the ground, and followed MY scent right back to me, climb up on my feet and were content. They are only two days old!!
