Unless there was someone else involved with a criminal history, or, and I'm merely theorizing, if she were deceased, and they'd been doing drugs, and considering where they may have gotten them, they figure, someone may have been going to jail. They may have been thinking they'd be going to jail for murder, too, since she o.d. in his home. Young men, one of them, the parents are strictly anti-drug, and he thinks he might be going to prison for murder. I could see someone panicking in that situation. Especially if they were still higher'n a Georgia Pine themselves.
