Former army sniper kills 4, including infant, in Florida shooting spree

A former sniper in the US military went on a shooting spree in central Florida, killing four people, including an infant boy in his mother's arms, officials said Sunday.
The suspect, identified as 33-year-old Bryan Riley, shot and killed a 40-year-old man, a 33-year-old woman and her three-month-old son in a residential area in Polk County, Florida, said County Sheriff Grady Judd.
The fourth victim was the child's 62-year-old grandmother.

Riley, who was wearing full body armour, also wounded an 11-year-old girl before surrendering himself to the police following an intense gunfight, Judd said.
Riley, a veteran of the wars in Iraq and Afghanistan, told the police he was a "survivalist" and that he had been taking methamphetamine.
The suspect also told the police, without elaborating, "You know why I did this," according to a statement from Judd published on social media.
Riley was wounded in the gunfight and was rushed to a local hospital, where he again tried to attack police officers and had to be sedated.
After he received medical help, the suspect was transferred to a local jail.
It was not immediately clear what prompted the attack, Judd said. An investigation is underway.
