If he left the contraband at his father’s,
why wouldn’t he have left the can of AriZona Watermelon Fruit Juice Cocktail and the Skittles there as well?
Would seem the smart thing to do, but then again if he was smart he’d still be breathing.
My speculation is he stashed something after he ran, maybe even in the pet station waste can at the T. He went back to get it.
