Michael Dunn, the Florida man who fatally shot an unarmed teenager over loud music, has been found guilty on three counts of attempted murder and one count of firing into a vehicle.

The jury could not reach a verdict on whether Dunn was guilty of the top count, that of the murder of 17-year-old Jordan Davis, whom Dunn killed when he fired into a vehicle of unarmed teenagers who were playing their music too loud.

Dunn is set to be sentenced in March and could face up to 75 years in prison.
