Former Marine wearing full body armor kills four people, including a mom holding a baby, in Florida

A man wearing full body armor fatally shot four people, including a mother and the 3-month-old baby she was cradling, and engaged in a massive gunfight with police and deputies before he was wounded and surrendered, a Florida sheriff said Sunday. An 11-year-old girl who was shot seven times survived.

Polk County Sheriff Grady Judd said during a press conference that even after 33-year-old Bryan Riley was arrested Sunday morning, he was so aggressive that he tried to wrestle a gun from police as he lay on his hospital gurney. Judd said Riley, a former Marine who served as a sharpshooter in both Iraq and Afghanistan, seemed to have targeted his victims at random and appeared to be suffering from mental health issues. Judd said Riley's girlfriend told authorities Riley had been slowly unraveling for weeks and repeatedly told her that he could communicate directly with God.
