(FOX NEWS) — Aaron Alexis, the gunman suspected in the killing of 12 people at a Navy building in Washington Monday morning, has been identified as a Navy veteran from New York who was arrested in two previous shooting incidents.
Alexis, who was discharged from the Navy two years ago after serving hitches in Texas and Illinois, sprayed bullets from the fourth floor down to the cafeteria area in the Naval Sea Systems Command headquarters in southeast Washington in an attack that began just after 8 a.m. Alexis, who may have used a stolen ID to get into the building, died later as he traded shots with responding police, though it was not clear if he killed himself or was brought down by cops.
