The Unknown Nidal Hasan

In the days before the Fort Hood shooting, Hasan tried to get rid of his few belongings. As one neighbor in the Casa del Norte apartment complex told ABC News, Hasan – a "soft-spoken guy" who was happy to do favors -- gave some of his furniture to another neighbor free of charge. But when ABC News toured Hasan's one-bedroom, $350-per-month apartment on Tuesday, traces of his conflicted private life remained.

In Hasan's living room, a crumpled prayer rug shared the floor with a paper-shredding machine. When he moved into the apartment in July, he'd put a bed in the bedroom, but he had gotten rid of the bed prior to the shooting.

In a closet, near the washer and dryer and wads of Hasan's clothing, including fatigues, was a box of pill bottles. The medications included a 2001 prescription for Combivir, a drug often prescribed for doctors who may have come in contact with HIV, as well as the antibiotic Clarithromycin, a cough reliever and an antihistamine.

On a card table in the kitchen were coins from various countries, including Israel, and an empty package for a LaserMax gun sight, with a $229.99 pricetag. There was also a book aboutIslamic dream interpretation, "Dreams and Interpretations," by Allamah Muhammad Bin Sireen. Anwar al Awlaki, the radical cleric in Yemen to whom Hasan had sent e-mails, has produced a lecture series on dream interpretation.
