Aaron Alexis, a 34-year-old man from Fort Worth, Texas, was identified as the shooting suspect in the rampage that killed 12 people at the Washington Navy Yard on Monday.
Scott Gordon of NBC-5 in Dallas-Fort Worth reported that Alexis was arrested by Fort Worth Police Department in 2010.
He recently began working as a civilian contractor for the Navy.
It is unclear what his motive was.
He entered the base with another man’s ID card, officials said. The name of the man whose ID card was found is being questioned.
