The suspected gunman in an airport shooting rampage in Fort Lauderdale, Fla. - Esteban Santiago, 26, an Iraq War veteran - has been charged with federal crimes and could face the death penalty, the Justice Department announced Saturday night. Investigators said Saturday that Santiago drew frequent police attention for domestic violence in his Alaska home town and twice was arrested within the last year. At least four times in 2016, police were called to Santiago's house for physical disturbances or domestic violence. Two months before the shooting ... he was admitted to a mental-health facility after showing up at an FBI field office and telling agents his mind was being controlled, complaining that the government was forcing him to watch Islamic State videos. Police held his gun for a month, and then gave it back to him, authorities said. Those sporadic run-ins now raise questions about how Santiago evaded detection as he boarded two flights - checking in a weapon - before he landed at the Fort Lauderdale-Hollywood International Airport and allegedly fired at unsuspecting travelers.
