 Ashley's autopsy shows that she didn't smoke marijuana that night. But Tom says that after she put the kids to bed, Ashley came into the bedroom defiant. And she's like, if I want to get high, I'll get high. I'm like, do whatever you want to. As Tom tells it, he was in their closet to change clothes when suddenly he heard the sound of a gun being loaded from across the room. She has a nine millimeter gun.
