WASHINGTON — At least 13 people were killed and several others wounded when a gunman opened fire at the Washington Navy Yard on Monday, in an attack that spread fear and chaos across the region.
The suspected gunman, identified by the FBI as Aaron Alexis, 34, of Fort Worth, was among the dead. Officials said Alexis was a military contractor and former Navy reservist, who reportedly had a previous run-ins with police over firearms.
Police Chief Cathy L. Lanier said investigators were looking for a possible second attacker who may have been disguised in a military-style uniform, but by nightfall, the attack increasingly appeared to be the work of a single gunman. Full story for BostonGlobe.com subscribers.
