Given that he probably had a radio and TV in the RV, is that plausible ? Was this in the papers ? Even if he had radio off would it be likely he would see a newspaper where he leaves off his RV ? I would assume the news was top of the hour every hour ? If I were LEO, I would have begun to be suspicious the minute he acted like he wasn't aware of her abduction.
He had been gone about 6 hours before he found out after returning to the neighborhood so he knew she was missing before LEO talked to him.
His MH storage place is on a man's property, Keith Sherman, not a public place.
I often drive with the radio off, even on long trips. I'm probably not the only one who does that.
