Later that day, Newport police alerted the Rhode Island naval station and sent a copy of the police report, Newport police Lt. William Fitzgerald said Thursday.
A spokeswoman for the station had no comment Tuesday.
Alexis came to the Washington area about two weeks later and had been staying at hotels. The day before the attack, he went to a Virginia gun store about 15 miles from the Navy Yard.
He rented a rifle, bought bullets and took target practice at Sharpshooters Small Arms Range, the store’s attorney Michael Slocum said. Alexis then bought a shotgun and 24 shells, according to Slocum.
The FBI said during Monday’s attack Alexis was armed with a shotgun. Officials said he also took a handgun from a law officer.
Alexis had run-ins with the law in 2004 and 2010 in Texas and Seattle after he was accused of firing a gun in anger.
And his bouts of insubordination, disorderly conduct and being absent from work without authorization prompted the Navy to grant him an early — but honorable — discharge in 2011 after nearly four years as a full-time reservist, authorities said.
Alexis joined the Florida-based IT consulting firm The Experts in September 2012, leaving a few months later to return to school. He came back in June to do part-time work at the Washington Navy Yard as a subcontractor, helping the military update computer systems.
The Experts’ CEO, Thomas Hoshko, told The Associated Press that Alexis had “no personal issues,” and he confirmed that Alexis had been granted a “secret” clearance by the Defense Security Service five years ago.
Alexis’s clearance — lower than “top secret” — doesn’t need to be renewed for 10 years. Still, the company said it hired outside vendors twice to check Alexis’ criminal history.
Alexis’ background check “came back clear,” Hoshko said.
