A former Marine outfitted in body armor fatally shot four people, including a baby, mother and grandmother, at a property outside Lakeland, Florida, early Sunday morning in what the local sheriff called an "active shooter rampage."
Riley served four years in the Marines and was honorably discharged, and then he did another three years in the reserve, Judd said. He was deployed to Iraq in 2008 and Afghanistan in 2009-2010 as a designated sharpshooter, the sheriff said.
Riley was employed by ESS Global Corp as a body guard and to provide security, Judd said. He has a concealed weapon's license and virtually no criminal history.
(While in custody, the suspect told deputies that he was a "survivalist," the sheriff said. The term generally refers to a person who proactively prepares for a post-apocalyptic world.)
