Good find. Here's a link to the information about the neighbor/shovel/car info. that you posted.
Neighbor: Marine Murder Suspect Borrowed A Shovel
This makes no sense when you take into account the bus guy that allegedly sold Maria the ticket and then said she had left her car at the station since Dec. 15th.
If the Marine borrowed a shovel to bury her, how stupid is that? The neighbor makes it sound like the wife might have been gone with her car not around during that week before Christmas.
