Defense begins case in loud music killing trial

JACKSONVILLE, Fla. (AP) — A private forensics expert testified for the defense on Monday that a rear passenger door of an SUV was likely open when a man fired into the vehicle during an argument over loud music, killing one of the teen passengers.

Forensics expert Michael Knox, called by the defense as its first witness, contradicted the testimony of other teens in the car who said the victim did not open the passenger door and physically threaten Michael Dunn, 47, in November 2012 before Dunn fired 10 shots into their vehicle, killing Jordan Davis, 17, from Marietta, Ga.
