Friday 8:00am Update:
The suspect in Thursday's deadly shootings at Fort Hood, Texas, is in stable condition, the hospital commander at the base said Friday.

Maj. Nidal Malik Hasan, a psychiatrist practicing at Darnall Army Medical Center at Fort Hood, was shot multiple times and was taken into custody, ending the shooting rampage Thursday afternoon, Fort Hood officials said.

The gunman opened fire at a military processing center at Fort Hood, killing one civilian and 12 soldiers, said Col. John Rossi, deputy commanding general at Fort Hood.

Twenty-eight people are still hospitalized and in stable condition, Rossi said at a news conference Friday morning. Hasan is the sole suspect in the shootings, Rossi said.

Authorities are investigating whether any of the killed or wounded were struck accidentally by someone trying to shoot the gunman, Rossi said.

Hasan was reported to have been wearing his uniform when he opened fire, said Col. Steven Braverman, hospital commander at Fort Hood. Braverman said Hasan had received orders to deploy to Afghanistan.

Friday Morning Update:
Officers early Friday raided the apartment of a soldier suspected in the deadly shootings at Fort Hood, Texas, searching for clues as to what caused the military psychiatrist to allegedly gun down soldiers he had taken an oath to help, a police spokeswoman said.

The alleged gunman, identified as Maj. Nidal Malik Hasan, opened fire at a military processing center at Fort Hood, killing 13 and wounding 30 others, Lt. Gen. Robert Cone said.

Hasan, a psychiatrist practicing at Darnall Army Medical Center at Fort Hood, was shot multiple times and was taken into custody, ending the shooting rampage Thursday afternoon, Cone said.

In the nearby town of Killeen, a SWAT team and FBI agents were searching Hasan's apartment to help determine what caused the shooting, which military experts called the worst mass shooting at an American military base, Carol Smith, a Killeen police spokeswoman, said early Friday.

Hasan, 39, is a graduate of Virginia Tech and a psychiatrist licensed in Virginia. He previously worked at Walter Reed Army Medical Center. A federal official said Hasan is a U.S. citizen of Jordanian descent. Military documents show Hasan was born in Virginia and has never deployed outside the United States.

The shooting occurred in a building called the readiness center, one of the last stops before soldiers deploy and one of the first places soldiers go upon returning to the United States. Some of the victims were headed to Iraq or Afghanistan, said Col. Benton Danner. The names of the 12 fatally wounded victims have not yet been released.

At a news conference earlier in the day, Cone said the shooter had two handguns, one of them a semi-automatic. A witness in a building adjacent to where the shooting happened said soldiers were cutting up their uniforms into homemade bandages as the wounded were brought into the building.

Texas Gov. Rick Perry ordered that all flags in the state be lowered to half-staff until Sunday as a tribute to the victims. "We are deeply saddened by today's events but resolve to continue supporting our troops and protecting our citizens," he said.

Fort Hood is the largest military installation in the world and includes the Third Corps.  The base is adjacent to Killeen, 60 miles northeast of Austin.  The sprawling complex is home to at least 4,929 active duty officers and 45,414 enlisted. Civilian employees total nearly 9,000.

A spokesman at Dyess Air Force Base said the base is on heightened alert following this situation.
