A Florida man convicted of first-degree murder for shooting a teenager to death over loud music was sentenced to life without parole Friday. Michael Dunn, 47, was convicted of killing Jordan Davis, 17, in November 2012 after he shot into a SUV of four teenagers 10 times when an argument broke out over loud music coming from the teens' vehicle. Dunn was sentenced to an additional 90 years in prison for three attempted murder convictions and another 15 years for firing into an occupied vehicle. “Our justice system works. This case demonstrates that our justice system does work,” said Judge Russell Healey at the sentencing.

Dunn was found guilty on three counts of second-degree attempted murder in January, but a mistrial was declared on the first-degree murder charge. A jury in early October found Dunn, who is white, guilty of murdering Davis, who was black. Testimony during the sentencing, including a statement by Davis' father, Ron Davis, lasted about an hour. Prosecutors did not pursue the death penalty, according to NBC South Florida.
