Yes, the car situation is strange. But that dosen't mean he didn't have another way out of there. He could have planned to leave the vehicles to draw attention to intruders,rather than himself.

How many killers take the bodies with them? They found blood and bullett shells...someone was injured or killed in the home. Maybe all of them. It seems whenever there is a domestic killing, the bodies are usually removed to cover-up.

There's a case in Arizona. The husband killed his wife and kids and then blew-up the house. He's still on the lamb.

This could be revenge, but why risk taking the whole family with them,especially if someone is injured and bleedingOR dead? Why risk being caught with the bodies?

We'll know shortly, I hope.
