TUCSON, Ariz. (AP) -- Randy Loughner was always something of a recluse. But since his son's alleged shooting rampage in Tucson, the father has shut himself behind what one neighbor calls "an elaborate cage."
In recent weeks, Loughner has built a substantial wooden enclosure, more than 6 feet high, obscuring his front door and windows.
The four horizontal windows on the garage door have been papered over, the diamond-shaped openings atop the block wall to his back yard closed off with little plywood plugs.
Until Jan. 8, the couple's 22-year-old son, Jared, shared the modest beige block and brick home where the couple have lived for nearly three decades. Now, he sits in a cell, facing federal charges of attempting to assassinate U.S. Rep. Gabrielle Giffords and two of her aides.
