Worshippers hugged each other and raised their hands in prayer during the service, in which Jackson asked the congregation to pray for the 13 dead and 29 wounded that /*Maj. Nidal Malik Hasan*/ is accused of shooting. The chaplain also urged the crowd to pray for Hasan and his family "as they find themselves in a position that no person ever desires to be."
"And Lord, teach us to love and pray for those who rise up against us and pray for those who do us harm. We pray for Maj. Hasan. Asking that you do the work that only you can do in his life," Jackson said.
Across the sprawling post and in neighboring Killeen, soldiers, their relatives and members of the community struggled to make sense of the shootings. Candles burned Saturday night outside the apartment complex where Hasan lived. Small white crosses, one for each of the dead, dotted a lawn at a Killeen church on Sunday.
At least 16 victims remained hospitalized with gunshot wounds, and seven were in intensive care.
Even as the community took time to mourn the victims at worship services on and off the post, Col. John Rossi acknowledged that the country's largest military installation was moving forward with its usual business of soldiering. The processing center where Hasan allegedly opened fire on Thursday remains a crime scene, but the activities that went on there were relocated, with the goal of reopening the center as soon as Sunday.
/*Fort Hood*/ is "continuing to prepare for the mission at hand," Rossi said. "There's a lot of routine activity still happening. You'll hear cannon fire and artillery fire. Soldiers in units are still trying to execute the missions we have been tasked with."
But the specter of the shooting lingers on the post. Rossi acknowledged that psychic wounds could be deep.
"The piece that most are troubled with right now is the location of where it happened and how it could happen," he said. "We know that problems sometimes take a while to manifest themselves in an individual and might come up in a later time period."
Military criminal investigators continue to refer to Hasan as the only suspect in the shootings but won't say when charges would be filed. Hasan, who was shot by civilian police to end the rampage, was in critical but stable condition at an Army hospital in San Antonio. He was breathing on his own after being taken off a ventilator on Saturday, but officials won't say whether Hasan can communicate.
A government official speaking on condition of anonymity because the person was not authorized to discuss the case said an initial review of Hasan's computer use has found no evidence of links to terror groups or anyone who might have helped plan or push him toward the attack. The review of Hasan's computer is continuing, the official said.
Army investigators on Sunday were searching for additional evidence to put together a comprehensive bullet trajectory analysis. Investigators were "seeking any military or civilian personnel who may have left the scene ... with gunshot damage such as damaged privately owned vehicles," Fort Hood spokesman Chris Haug said in a statement.
Hasan likely would face military justice rather than federal criminal charges if investigators determine the violence was the work of just one person.
Sen. Joe Lieberman, chairman of the Senate Homeland Security and Governmental Affairs Committee, said he plans to begin a congressional investigation to determine whether the shootings constitute a terrorist attack. Lieberman, an independent from Connecticut, said on "Fox News Sunday" that he wants to find out whether the Army missed warning signs that Hasan was becoming extreme.
"If Hasan was showing signs, saying to people that he had become an Islamist extremist, the U.S. Army has to have zero tolerance," he said. "He should have been gone."
Army Chief of Staff George Casey warned against reaching conclusions about the suspected shooter's motives until investigators have fully explored the attack. He said on ABC's "This Week" that focusing on Hasan's Islamic roots could "heighten the backlash" against all Muslims in the military.
There had been signs in recent months that Hasan's growing anger with the U.S. wars in Iraq and Afghanistan were at odds with his military service, including his comments that the war on terror was "a war on Islam." Others who knew Hasan, an Army psychiatrist, said he had wrestled with what to tell fellow Muslim solders who had their doubts about fighting in Islamic countries.
"I told him, `There's something wrong with you,"' Osman Danquah, co-founder of the Islamic Community of Greater Killeen, told The Associated Press on Saturday. "I didn't get the feeling he was talking for himself, but something just didn't seem right."
Danquah assumed the military's chain of command knew about Hasan's doubts, which had been known for more than a year to Hasan's classmates at a Maryland graduate military medical program. There, students complained to faculty about Hasan's "anti-American propaganda," but said a fear of appearing discriminatory against a Muslim student kept officers from filing a formal complaint.
