(Red Huber/Orlando Sentinel via AP, Pool) (Newser) – A Florida man who fired a gun at George Zimmerman's truck during a road-rage confrontation was convicted of attempted second-degree murder Friday, the AP reports. Jurors also found 37-year-old Matthew Apperson guilty of shooting into a vehicle and aggravated assault with a firearm. He faces sentencing Oct. 17. Apperson testified that he acted in self-defense last year. He said he fired at Zimmerman because Zimmerman flashed a gun. But prosecutor Stewart Stone told jurors that Zimmerman's vehicle had tinted windows, which were rolled up during the confrontation. Apperson's attorney, Michael LaFay, attacked Zimmerman's credibility, calling him a liar. Zimmerman was acquitted three years ago in the fatal shooting of Trayvon Martin, an unarmed black 17-year-old. That case sparked protests and a national debate about race relations.
