Esteban Santiago is accused of shooting five people dead and wounding another six at the Fort Lauderdale airport earlier this month.
Fox News is now reporting Santiago had his guns seized twice by authorities before the Jan. 6 shooting spree, including a reported confiscation four years ago in Puerto Rico.
However, on both occasions authorities decided to close the investigations and return the guns back to the deranged killer.
Santiago, 26, had a gun or guns taken by Penuelas police in Puerto Rico more than four years ago, The Florida Sun-Sentinel reported on Friday, though the reason for the action wasn’t immediately clear.
The investigation lasted about two years and Santiago’s firearms were eventually returned to him in May 2014.
Shortly after his guns were returned, Santiago moved to Anchorage, where in November 2016 he had walked into an FBI office and allegedly told authorities that ISIS was influencing him and the government was attempting to control his mind.
Federal agents again seized Santiago’s weapon and he was given a mental health evaluation – but doctors didn’t think he needed to be committed, Santiago was released and his gun was returned on Dec. 8.
It’s unclear if the weapons were the same in the two cases, or if any of those weapons were the same Walther 9-mm. semi-automatic handgun Santiago allegedly used during the baggage claim slaughter.
Nor is it clear why Santiago went to Florida.
He had some family there, but they said they hadn’t seen him in years. He had also booked, and canceled, another flight, an Alaska-to-Puerto Rico trip that would have included a layover in New York on New Year’s Day, according to a law enforcement official.
