The man suspected of killing five people Friday at Fort Lauderdale’s airport has been identified as Esteban Santiago, Broward County Sheriff Scott Israel said.
Here is what we know about the suspected shooter:
• Santiago flew into Florida on a flight from Alaska via Minnesota on a Delta flight, officials said. He had declared his handgun in a firearms carrying case, law enforcement sources told CNN.
• Upon arriving at Fort Lauderdale-Hollywood International Airport, he picked up the carrying case at baggage claim, took out the gun and started firing, according to law enforcement sources.
• One source said Santiago went to the bathroom to get the gun out of the case and emerged shooting.
• Santiago likely acted alone, Israel said.
• The FBI is investigating every angle and has not ruled out terrorism, according to officials.
• Santiago is in federal custody and will likely appear Monday in court in Broward County, officials said.
• Santiago had purchased two handguns — a 9 mm Glock and a Glock .40-caliber — in the past, according to a law enforcement source with knowledge of the investigation. It is unknown whether either of these pistols were used in Friday’s attack.
• Santiago’s criminal record in Alaska includes three minor offenses: having no proof of insurance in 2015; a tail light violation in 2015 and a criminal mischief charge, causing property damage of more than $50, in 2016
• He served in the Puerto Rico National Guard and the Alaska Army National Guard.
• He joined the Puerto Rico National Guard on December 14, 2007, said Lt. Col. Candis Olmstead of the Alaska Army National Guard.
• Santiago was deployed to Iraq with the Puerto Rico National Guard from April 23, 2010, to February, 19, 2011, said Olmstead.
• Santiago received the Iraq Campaign Medal with a campaign star, a combat-related honor, CNN’s Barbara Starr reported.
• He served in the US Army Reserve before joining the Alaska Army National Guard on November 21, 2014, Olmstead told CNN.
• Santiago was later given a general discharge from the Alaska Army National Guard on August 16, 2016, for unsatisfactory performance.
• Santiago was not on the radar for possible terrorism ties, according to a law enforcement official and a Department of Homeland Security official.
• Santiago had no significant foreign travel that was ever flagged, another official said.
• He visited the FBI’s Anchorage, Alaska, office a few months ago and told them an intelligence agency was telling him to watch ISIS videos, according to law enforcement officials.
• The officials said Santiago’s associates were concerned because he said he was hearing voices; they had accompanied him to the FBI office in Anchorage.
• The FBI looked into Santiago’s background and saw his military history but found no information to indicate radicalization, officials said. The FBI asked local police to take him to the hospital for a mental health evaluation. Santiago voluntarily checked himself in.
• Santiago lived in Alaska and was employed by an Anchorage security company, a law enforcement official said.
