FORT HOOD, Texas (AP) Authorities say the Fort Hood shooting suspect cleaned out his apartment, gave food to a neighbor and thanked another for his friendship, common courtesies of a departing soldier.

Officials say Maj. Nidal Malik Hasan (nih-DAHL' mah-LEEK' hah-SAHN') then went on the killing spree that left 13 people dead, firing more than 100 rounds.

Investigators have examined Hasan's computer, his home and his garbage. They say the guns used were bought locally, near the Texas base.

Hasan is hospitalized and in a coma after being shot four times.

Hospital officials say some of the wounded have extremely serious injuries and might not survive.

Relatives say Hasan felt harassed as a Muslim but was not an extremist.

A recent classmate says Hasan once gave a jarring presentation in which he argued the war on terrorism was a war against Islam.
