BRADENTON, Fla. (AP) - A teen has been sentenced to 25 years in prison for fatally shooting a Manatee County high school student.

As part of a plea deal, 19-year-old Daniel Floyd Williams pleaded no contest Monday to manslaughter with a firearm. He could have faced life in prison if convicted of second-degree murder at a trial scheduled for next month.

Authorities say Williams shot 17-year-old Jazmine Thompson, a cheerleader at Bayshore High School, while she was sitting in the back of a car after a football game last fall. Police say Williams became involved in a verbal confrontation with other girls in the car and then fired at least four shots at the vehicle while he was walking away.

The girls in the car reportedly didn't realize that Thompson had been shot until they drove to her home.
