( CNN ) -- A soldier suspected of fatally shooting 12 and wounding 31 at Fort Hood in Texas on Thursday is not dead as previously reported by the military , the base 's commander said Thursday evening . A civilian officer who was wounded in the incident shot the suspect , who is `` in custody and in stable condition , '' Army Lt. Gen. Robert Cone told reporters . `` Preliminary reports indicate there was a single shooter that was shot multiple times at the scene , '' Cone said at a news conference . `` However , he was not killed as previously reported . '' The suspect , identified as Maj. Nidal Malik Hasan , opened fire at a military processing center at Fort Hood around 1:30 p.m. , Cone said . Three others initially taken into custody for interviews have been released , Cone said . Hasan , 39 , is a graduate of Virginia Tech and a psychiatrist licensed in Virginia who was practicing at Darnall Army Medical Center at Fort Hood , according to military and professional records . Previously , he worked at Walter Reed Army Medical Center . A federal official said Hasan is a U.S. citizen of Jordanian descent . Military documents show that Hasan was born in Virginia and was never deployed outside the United States . In a statement released Thursday , Hasan 's cousin , Nader Hasan , said his family is `` filled with grief for the families of today 's victims . '' `` Our family loves America . We are proud of our country , and saddened by today 's tragedy , '' the statement said . `` Because this situation is still unfolding , we have nothing else that we are able to share with you at this time . '' Hasan was scheduled to be deployed to Iraq `` and appeared to be upset about that , '' Sen. Kay Bailey Hutchison , R-Texas , said . `` I think that there is a lot of investigation going on now into his background and what he was doing that was not known before , '' Hutchison said . Hutchison said she was told that the soldiers at the readiness facility `` were filling out paper processing to go to Iraq or Afghanistan , '' according to CNN affiliate KXAN in Austin , Texas . The readiness center is one of the last stops before soldiers deploy . It is also one of the first places a soldier goes upon returning to the United States . The base reopened Thursday night after being under lockdown for more than five hours . At a news conference earlier in the day , Cone said at least 10 of the dead were soldiers . The shooter had two weapons , both handguns , Cone said . iReport.com : Are you there ? Send pics , video . 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 . `` It was total chaos , '' the witness said . Cone said a graduation ceremony was being held in an auditorium just 50 meters from where the shooting took place . `` Thanks to the quick reaction of several soldiers , they were able to close off the doors to that auditorium where there were some 600 people inside , '' he said . Peggy McCarty of Missouri told CNN affiliate KSHB that her daughter , Keara Bono , was among Thursday 's wounded . She said she briefly spoke to Bono , who told her she had been shot in her left shoulder but was doing well . `` She 's being deployed to Iraq on December 7 , '' McCarty said . `` I thought I was more worried about her going over to Iraq than here , just doing training in Texas . She just got there yesterday . '' A woman who lives on base , about eight blocks from the shooting , said she and her daughter were at home when her husband called and told them to stay inside . `` And I asked him why , what was going on . He said that there was a shooting , '' said the woman , Nicole , who asked that her last name not be used . She said her husband called her back about 20 minutes later and told her to go upstairs , stay away from doors and windows and keep the doors locked . `` It 's just been crazy , '' she said . `` Sirens everywhere . '' A soldier who asked not to be identified told CNN that an e-mail went out to all base personnel instructing them not to speak to the media . President Obama called the shootings `` tragic '' and `` a horrific outburst of violence . '' He expressed his condolences for the shooting victims . `` These are men and women who have made the selfless and courageous decision to risk , and at times give , their lives to protect the rest of us on a daily basis , '' Obama said . `` It 's difficult enough when we lose these brave Americans in battles overseas . It is horrifying that they should come under fire at an Army base on American soil . '' Scott & White Memorial Hospital in Temple , Texas , posted an online appeal for blood as it began receving victims . `` Due to the recent events on Fort Hood , we are in URGENT need of ALL blood types , '' it said . Fort Hood , with about 40,000 troops , is home to the Army 's 1st Cavalry Division and elements of the 4th Infantry Division , as well as the 3rd Armored Cavalry Regiment and the 13th Corps Support Command . It is located near Killeen , Texas . The headquarters unit and three brigades of the 1st Cavalry are currently deployed in Iraq . At least 25,000 people are at Fort Hood on any given day , an Army spokesman at the Pentagon said . Fort Hood is home to the Warrior Combat Stress Reset Program , which is designed to help soldiers overcome combat stress issues . In June , Fort Hood 's commander , Lt. Gen. Rick Lynch , told CNN that he was trying to ease the kind of stresses soldiers face . He has pushed for soldiers working a day schedule to return home for dinner by 6 p.m. , and required his personal authorization for anyone working weekends . At the time , two soldiers stationed there had committed suicide in 2009 -- a rate well below those of other posts . Nearby Killeen was the scene of one of the most deadly shootings in American history 18 years ago when George Hennard crashed his truck into a Luby 's Cafeteria and began shooting , killing 23 people and wounding 20 . Hennard 's spree lasted 14 minutes . He eventually took his own life .
