I remember JP making statements about how he had to go shopping because he had to replace items LE took in the search. Bedspred, phone, etc. But, I can't remember if that would have been in his car or the rental.

former neighbor Tim Peterson audio interview states that he was the one who took Josh to get his van back from the police, mentions Joshs frustration about having to replace the bedspread, cellphone (apparently not frustrated about his wife being missing though)
