A gunman who opened fire at the Washington Navy Yard on Monday, killing at least 12 people, has been identified by his fingerprints as Aaron Alexis, a 34-year-old former Navy serviceman.
The FBI is now seeking information about Alexis, naming him the deceased suspect on its website. Alexis was arrested in 2004 after shooting the tires of a vehicle driven by construction workers doing a job in his neighborhood in Seattle, police said. He told officers he was having an anger-fueled "blackout" at the time he fired shots after he felt the workers mocked him. Officers said he also told them he was in NYC the day of the Sept. 11 attacks and felt "disturbed" by the events.
Public records website Busted Mug Shots has an arrest record for Alexis from Sept. 4, 2010, for discharge of a firearm in Fort Worth, Texas. No charges were filed after police determined Alexis accidentally fired the gun while cleaning it.
Aaron Alexis' father, Algernon Alexis, told Reuters he was stunned by the news of his son's involvement. He said his son, who served in the Navy from 2008 to 2011, was studying while working a computer-related job for a private company.
"This comes as a complete shock," he said.
Alexis recently moved from Fort Worth to D.C. to work as a civilian contractor. He was a Brooklyn native who spoke Thai and mediated regularly at a Buddhist temple. He had also worked as a waiter in a Thai restaurant.
Alexis reportedly carried several guns with him during Monday's attack, including an assault rifle. At least 13 people, including Alexis, were killed in today's rampage. Several others were also injured.
