The suspect believed to have shot five people to death in a rampage at a Florida airport Friday was being treated in Alaska after complaining of hearing voices and had recently claimed to the FBI that the CIA was forcing him to watch ISIS videos, federal officials said.
Esteban Santiago, 26, was identified as the gunman who opened fire at a baggage claim at the Fort Lauderdale-Hollywood International Airport at 12:55 p.m., apparently shooting people at random.
Santiago had been "fighting with a lot of people," his brother, Bryan, told NBC News in a phone interview from Puerto Rico. His aunt and uncle in New Jersey said Santiago had not been the same since a 10-month deployment in Iraq with the Puerto Rico National Guard."Sometimes he's good. Sometimes something weird," Bryan Santiago said. "He had a woman there in Alaska, a child. He fight verbally too much with her. I can tell you he fight too much with everybody."
