KILLEEN (November 5, 2009)—The Casa Del Norte Apartment complex at 1801 N. 4th St. in Killeen was surrounded and evacuated Thursday night as authorities prepared to search the second-floor apartment in which suspected Fort Hood gunman Maj. Nidal Malik Hasan lived.

Hasan is the Army psychiatrist suspected of opening fire at around 1:30 p.m. Thursday on post, killing 12 and injuring 30.

He was originally thought to be among the dead, but Thursday night, post officials said he survived.

He was reportedly shot at least four times.

A clerk at the 7-Eleven store at Fort Hood St. and Hallmark in Killeen told News 10 Hasan was dressed in full Muslim garb when he stopped to buy coffee Thursday morning.

She said Hasan stopped by the store three or four times a week, but said his dress Thursday was out of the ordinary.

She said when she asked him about it, he replied that he sometime wore traditional dress in the mornings.

She said nothing else seemed out of the ordinary and said she was shocked when Hasan was identified as the gunman.

Killeen police and the Killeen Police Department SWAT Team surrounded the two-story apartment building where Hasan lived late Thursday afternoon and evacuated about 20 residents, who were taken to the Killeen Community Center, police Lt. Jeff Donohue said.

Officers were waiting Thursday night for Fort Hood’s bomb team, which will check out the building as a precaution, Donohue said.

Police don’t think anyone else is inside the building, but Donohue said they don’t want to take any chances.

One of the evacuated residents, Edward Windsor, said he was shocked to learn his neighbor was suspected in the rampage.

“He never gave any indication he could do something like this,” Windsor said.

Hasan is an Army psychiatrist who spent six years at Walter Reed Army Medical Center before he was transferred to Fort Hood in July, officials told The Associated Press.

The officials, who had access to Hasan's military record, said he received a poor performance evaluation while at Walter Reed.

The officials spoke on condition of anonymity because military records are confidential.

A female civilian shot Hasan shot after the rampage.

He was originally reported to be dead, but Fort Hood Commander Lt. Gen. Bob Cone said Thursday night Hasan survived.

Thursday night, Killeen police and swat teams surrounded two-story apartment building in the 1800 block of North 4th Street in Killeen, where Hasan’s lived.

The complex was evacuated and about 20 residents were taken to the Killeen Community Center.

The Virginia-born soldier was single with no children.

He was 39 years old and was a graduate of Virginia Tech University, where he was a member of the ROTC and earned a bachelor's degree in biochemistry in 1997.

He received his medical degree from the military's Uniformed Services University of the Health Sciences in Bethesda, Md., in 2001.

He did his internship, residency and a fellowship at Walter Reed.

Sen. Kay Bailey Hutchison, R-Texas, said Hasan was about to deploy overseas.

Hutchison said she was told about the upcoming deployment by generals based at Fort Hood, but it was unclear if he was headed to Iraq or Afghanistan and exactly when he was scheduled to leave.

Federal law enforcement officials said Hasan came to their attention at least six months ago because of Internet postings that discussed suicide bombings and other threats.

The officials say the postings appeared to have been made by Hasan, but said they are still trying to confirm that he was the author.

They said an official investigation was not opened.

The officials spoke on condition of anonymity because they were not authorized to discuss the case.

One of the Web postings that authorities reviewed is a blog that equates suicide bombers with a soldier throwing himself on a grenade to save the lives of his comrades.

Hasan’s cousin, Nader Hasan of Falls Church, Va., said in a statement late Thursday that he and his family are filled with grief for the families of the victims.

He said Nidal Hasan's family knows little about what happened, but that they want to send "our most heartfelt sympathies" to the families of the victims.

He also said that Hasan was raised in America, and that his family loves and is proud of their country.
