Alexis was arrested three times in three states for acts of rash, inexplicable violence. He told Seattle police in 2004, for example, that he’d had an anger blackout so intense that he couldn’t recall shooting three rounds from the .45-caliber Glock he usually kept strapped tightly to his waist.
An upstairs neighbor in Texas in 2010 told police she was terrified of him after a gunshot came through the floor a few feet from where she was sitting.
Three other times, in other states, he was cited in police reports for acts of aggression or hallucinations.
Twice, medical staff at swamped Veterans Health Administration emergency rooms in Providence, R.I., and the District failed to pick up on Alexis’s deteriorating mental stability, despite new protocols designed to screen for it, the records and interviews show.
Navy security officials, warned in August by police in Rhode Island that Alexis was hearing voices, a key indicator of a mental break, failed to notify the technology company where he worked, a Navy official said, nor did they appear to pass the information up the chain of command.
Alexis’s employer, an IT company called the Experts, was so concerned about Alexis’s increasingly agitated state over the summer that they called his mother and sent him home to rest, but they say they did not share their concerns with the Navy.
His outbursts never made it into a national database that would have notified police among different jurisdictions and turned up in background checks for gun purchases, enlisting in the military or obtaining a mid-level secret security clearance. That system is designed to catch Cold War-era spies intent on selling national secrets, not monitor people for mental health problems.
In fact, some experts said, his security clearance, rather than acting as an early warning system, actually helped Alexis avoid greater scrutiny. His clearance was an indication for many that Alexis could be trusted.
The VA staff, trained to catch and treat such mental instability, often are so overworked and understaffed that they fail to do so, the records and interviews indicate. And military and company officials failed to act on clear warning signals that Alexis was spiraling dangerously out of control.
And so on Monday, about 8:15 a.m., Alexis, who was known for his explosive temper and smoldering grudges, who sought refuge from his jangled thoughts at Buddhist temples and in meditation, and who had been estranged from his family for years, quietly slipped onto the Washington Navy Yard base with a sawed-down Remington 870 shotgun hidden in a bag. He emerged from a bathroom and killed 12 people before police shot him dead.
