Alex Neumann told cable network CNN that he was in an area inside the airport past a security checkpoint when he heard loud noises and screaming and saw people running in a scene that amounted to mayhem. “We were at the food court and all of a sudden I hear a big commotion and people started running. People were running and people [were] getting knocked down,” Neumann said, adding that he heard screams. “Mayhem is the best way of describing it.”

Reuters Wire: LA Fire Department describes situation at LAX as "multi-patient incident"

Transcript: Statement of FBI Assistant Director in Charge Valerie Parlave:

"I would first like to commend and thank the agencies you see here with me today, as well as many others. We continue to actively work together, and the partnerships and cooperation among us are vital to the progress of this investigation.

"As briefed last night, we believe at this time that the deceased shooter, Aaron Alexis, acted alone. As such, with no other suspects at large, the investigation has moved into a phase of evidence recovery and information gathering. We have 13 confirmed fatalities, to include the shooter, all of whom have been positively identified.

"Our Evidence Response Teams remain at the Navy Yard and continue to process the scenes. As I mentioned last night, this is a methodical and time-intensive process that includes bullet trajectory analysis and crime scene mapping, and, with the assistance of Evidence Response personnel from our Baltimore and Richmond Field Offices, we will remain there for as long as necessary to carefully process each shooting site."

Nevada Senator Harry Reid spoke on the Senate floor on Tuesday on the mass shooting at the Washington Navy Yard:

"No words of condolence could possibly ease the pain of a dozen families who lost loved ones in yesterday’s Navy Yard shooting rampage. But I hope it is some small comfort that a city and a nation mourn alongside them.

"There is still no explanation for the terrible violence that occurred yesterday. My thoughts are with those who were injured. I wish them a speedy recovery. And my heart goes out to all of the 16,000 military and civilian employees who work in the Navy Yard complex, as well as their friends and family members, who were affected by this tragedy.

"Just a few days ago, members of Congress marked the anniversary of September 11, 2001 during a ceremony on the steps of the United States Capitol. Yesterday’s shootings are the worst loss of life in the Capitol region since the Sept. 11 attack on the Pentagon. Both last week’s significant anniversary and yesterday’s terrible violence are a reminder that life is fragile and precious. And they are a reminder of the debt we owe to those who protect our freedom and our safety – whether they serve in the military or as first responders.

My thanks go to all those who put their lives on the line to prevent greater loss of life Monday, including the entire Washington, D.C. law enforcement community. I thank Senate Sergeant at Arms Terry Gainer, who is responsible for our safety here in the Capitol. And in particular, this city owes a debt of gratitude to Metropolitan Police officer Scott Williams, a K-9 officer and 24-year veteran of the force, who was hurt very badly. I wish Officer Williams a full recovery and thank him for his selflessness."

A U.S. Navy official said on Tuesday that the Navy Secretary has ordered a security review for all navy and marine corps installations, and that the first stage of the security review will look at existing physical security standards.

Navy Yard suspect is ex-military man, once worked in Thai restaurant

A man suspected of the shooting at the U.S. Navy Yard in Washington, D.C. on Monday was described as a former military serviceman known to have at one time worshipped at a Buddhist temple and worked in a Thai restaurant.

The FBI identified Aaron Alexis, 34, as a suspect who was among at least 13 people killed in the shooting not far from the U.S. Capitol and the White House. It was unclear whether Alexis was working at the U.S. Navy Yard in a civilian capacity at the time of the shooting, an official said.

Public records indicated that since 1998, Alexis lived in New York, Texas and Washington states. In September 2010 in Fort Worth, Texas, he was arrested for illegally discharging a firearm, but the case was not pursued, a county prosecutor's spokeswoman said.

Alexis had served in the military but most recently was furthering his education while holding down a job in the private sector, his father Algernon Alexis, said in a telephone interview.

"This comes as a complete shock," the elder Alexis said when he was told his son was identified as a suspect in the shooting.

His father said he was currently "in school and working at a job" at a private company in a "computer-related" position outside of his birthplace, New York.

Alexis worked at the "Thai Bowl" restaurant in 2008, said Tiki Confer, 64, the owner of the Bangkok House Thai restaurant in White Settlement, Texas. She said he spoke Thai and worshipped at a Buddhist temple.

"He was a very nice boy. When I saw his picture on the news, I was shocked," Confer said.

A U.S. Navy official said that Alexis served full time in the U.S. Navy's Reserve from May 2007 to January 2011. He reached the rank of Aviation Electrician's Mate 3rd Class.

He received two awards that are common for military personnel, the National Defense Service Medal and the Global War on Terrorism Service Medal.

Alexis was arrested on September 4, 2010 in Fort Worth on a misdemeanor charge for firing a gun, said Melody McDonald, spokeswoman for the Tarrant County District Attorney's office.

"It was determined that Alexis was cleaning a gun in his apartment when it accidentally went off," McDonald said in a statement. "A bullet entered an apartment upstairs. No one was injured."
