I think I heard the closet hidey hole was also the storage place for the husband's guns. The neighbors in the area say the closet-dude was a Mexican boxer. The murderer hid in the rafters of a nearby house (still under construction) for over two hours while the owner of the new house walked around and made decorating decisions. The owner heard a noise in the attic but thought it was an animal. When the police banged on the door and said there had been a murder nearby, they directed the police to the attic and the rest is history.
Wrong..see, the closet was rent controlled, and the husband wanted to raise the rent to market rate, so the tenant got frustrated and blew him away..
