A police spokesman said Zimmerman and his wife, who filed for divorce last week, were blaming each other for starting the fight at her father's home. In an audio recording of Shellie Zimmerman's 911 call, she can be heard saying Zimmerman smashed an iPad she was holding and cut it with a pocket knife, struck her father in the nose and threatened both while putting a hand on a gun. Deputy Police Chief Colin Morgan said officers did not recover a gun, and Bracknell said Shellie Zimmerman later dropped her claim that a gun was involved. "Domestic violence can't be invoked because she has changed her story and says she didn't see a firearm," Bracknell said. The dispute "was between him and his wife and her father,'' Morgan said. "There were some allegations that there had been an assault, but we could not confirm any of it.'' Zimmerman has been pulled over at least twice for speeding since his acquittal. http://www.usatoday.com/story/news/nation/2013/09/09/george-zimmerman-gun-incident-florida-trayvon-martin/2788443/
