10:54 a.m. - U.S. officials say Aaron Alexis had a string of misconduct problems during his nearly three years in the military, but he received an honorable discharge. The officials say that Aaron Alexis, 34, had bouts of insubordination, disorderly conduct and was sometimes absent from work without authorization. The offenses occurred mainly when he was serving in Fort Worth, Texas, from 2008-2011, and were enough to prompt Navy officials to grant him an early discharge through a special program for enlisted personnel.

Officials said the bad conduct was enough to make it clear Alexis would not be a good sailor, but not enough to warrant a general or less-than-honorable discharge.

10:30 a.m. - Defense Secretary Chuck Hagel laid a wreath in memory of the 12 shooting victims at the "The Lone Sailor" statue at Washington's U.S. Navy Memorial plaza reports CNN. The U.S. Senate also observed a moment of silence; the House will do the same at 7 p.m.

But certainly, as I look at for example sequestration, which is about saving money in the federal government being spent, that we somehow skimped on what would be available for projects like this, and then we put people at risk. Obviously 12 people have paid the ultimate price for whatever — you know, whatever was done to have this man on the base.”

9:22 a.m. - CNN reports three people injured in the shooting are doing better today at MedStar Washington Hospital Center .A Washington male police officer and a female civilian are both in fair condition and a second female civilian is in good condition.

7:57 a.m, - The Associated Press reports that Navy yard gunman Aaron Alexis had been treated since August by the Veterans Administration for serious mental illness including including paranoia, a sleep disorder. and  `hearing voices." The Navy had not declared him mentally unfit, which would have rescinded a security clearance that Alexis had from his earlier time in the Navy Reserves.

Fast Moving Developments

Following the confusion and fast moving developments of Monday in which there were believed to be three gunman at one point, the FBI says there was only one shooter. They are trying to determine a motive and are asking the public for any information about Alexis, a Queens native who grew up in Brooklyn. "No piece of information is too small," Valerie Parlave of the FBI said Monday night according to CNN. "We are looking to learn everything we can about his recent movements, his contacts and associates."

"We do now feel comfortable that we have the single and sole person responsible for the loss of life inside the base today," Washington police Chief Cathy Lanier said.

A profile of Alexis, 34,  was coming into focus. He was described as a Buddhist who had also had flares of rage, complained about the Navy and being a victim of discrimination and had several run-ins with law enforcement, including two shootings.

The owner of a Thai restaurant in Texas frequented by Alexis describes him to the Washington Post as a "“13-year-old stuck in a 34-year-old body" who "needs attention."

Alexis carried three weapons: an AR-15 assault rifle, a shotgun, and a handgun that he took from a police officer at the scene, according to two federal law enforcement officials who spoke on condition of anonymity because they were not authorized to discuss the investigation. The AR-15 is the same type of rifle used in last year's mass shooting at a Newtown, Conn., elementary school that killed 20 students and six women. The weapon was also used in the shooting at a Colorado movie theater that killed 12 and wounded 70.

Meanwhile, it took hours to process 2,000 civilians at the Navy Yard before they could leave. The Washington Post reported that the FBI was interviewing every person before they left which discovered new information including a bag with a letter to one of the victims. The Navy Yard is closed today.
