WASHINGTON (AP) - Investigators are building a profile of the lone gunman in Monday's mass shooting at the Washington Navy yard.
Aaron Alexis is being described as a Buddhist convert, but someone known to have flares of rage.
The 34-year-old former Navy reservist had prior run-ins with law enforcement, including two shootings. Police in Seattle say Alexis was arrested there in 2004 for shooting out the tires of another man's vehicle in what he described to detectives as an anger-fueled "blackout." The other incident occurred in Texas in 2010.
While some neighbors and acquaintances describe Aaron Alexis as "nice," his father once told detectives in Seattle that his son had anger management problems related to post-traumatic stress brought on by the Sept. 11 attacks. He also complained about the Navy and being a victim of discrimination.
Alexis and a dozen victims were killed in yesterday's attack.
