Michael Dunn, a middle-aged white man, was sentenced to life in prison without parole, plus 90 years, by a Florida judge on Friday for killing an unarmed black teenager in an argument over loud rap music.
Dunn, 47, a software engineer, testified at his murder trial last month he thought he was defending himself from an armed threat when he fired 10 rounds at an SUV carrying four teens at a Jacksonville gas station parking lot, killing Jordan Davis, 17, in November 2012.
Under Florida law, first-degree murder is punishable by life in prison without parole. Prosecutors waived the death penalty before trial.
