Five people have been killed and eight have been wounded in a shooting Friday at the Fort Lauderdale airport, the Broward County Sheriff's Office said on Twitter.
The gunman, identified as Esteban Santiago, 26, is in custody and was a lone shooter, Broward County Mayor Barbara Sharief told CNN on Friday.
"We have no evidence at this time that he was acting with anyone else. He is currently in custody and we're investigating," Sharief said. Investigators are looking into the suspect's motive, she said.

Parts of the airport were apparently evacuated. Aerial footage from CNN affiliates showed large groups of people standing outside on the tarmac.
Airport officials said on Twitter that there is an "ongoing incident" in the baggage claim area of Terminal 2.
Multiple reports on social media — including tweets from former White House spokesman Ari Fleischer, described the shooting.

"I got off the plane and I saw people running and screaming. At first I was in shock but when I saw TSA agents running, I booked," Messina told CNN over Instagram.
In November 2016, nearly 2.5 million travelers passed through Fort Lauderdale's airport, according to a government report on the facility.
There are four terminals at the airport.
