After news broke on Saturday morning that a gunman had opened fire in a Florida airport, details have slowly come to light about who was involved and the timeline that led to the tragedy.
This is what we know so far.
At about 1pm local time, and at about 5am AEDT, a gunman opened fire at a baggage carousel at terminal two at the Fort Lauderdale-Hollywood International Airport in Florida.
Five people were killed and eight were wounded, Broward County Sheriff Scott Israel told reporters at the airport, the ABC reports.
According to Broward County Commissioner Chip LaMarca on Twitter, the gunman had arrived at the airport on a flight along with a gun in his checked bag. Transport Security Administration rules dictate that firearms can legally be carried in checked luggage if they are unloaded and stored in a locked and hard-walled container.
Upon arrival at the airport, the shooter retrieved his bag, headed to the bathroom to load the gun before opening fire at a baggage carousel.
He was then taken into custody unharmed, after police did not fire any retaliation shots. It is believed he wore a Star Wars T-shirt and said nothing as he fired, witnesses told MSNBC. Air traffic has since been shut down at the airport indefinitely.
Fort Lauderdale-Hollywood International Airport is the second-largest airport in South Florida, behind Miami.
Who was involved?
The five who were killed and eight wounded are yet to be identified.
The suspected shooter has been identified as 26-year-old Esteban Santiago, who was carrying US military identification at the time of his arrest.
In an interview with NBC, Santiago’s brother Bryan said he had served in the National Guard in Puerto Rico for six years, and was deployed in Iraq for about a year in 2010.
“He was pro-America,” Bryan said, adding that “he is a regular person, spiritual, a good person.”
Upon his return to Puerto Rico from Iraq, Bryan said his brother struggled to find a job and moved to Alaska for work opportunities. However, he was recently hospitalised in Alaska after “something got to him”, his aunt told NBC sister station Telemundo-47.
“I know that right now he was working in security [in Alaska],” she said. “But about two months ago, he was in the hospital.”
