Zimmerman's wife calls 911 on husband but does not press charges LAKE MARY, Fla. - The sobbing wife of George Zimmerman called 911 Monday to report that her estranged husband was threatening her with a gun and had punched her father in the nose, but hours later she decided not to press charges against the man acquitted of all charges for fatally shooting Trayvon Martin. Lake Mary police officers were still investigating the encounter as a domestic dispute, but no charges had been filed Monday afternoon. George Zimmerman, wearing a flannel shirt, baseball cap and with sunglasses on, left the home after being questioned by police. Shellie Zimmerman, who has filed for divorce, told a 911 dispatcher that her husband had his hand on his gun as he sat in his car outside the home she was at with her father. She said she was scared because she wasn't sure what Zimmerman was capable of doing. But hours later she changed her story and said she never saw a firearm, said Lake Mary Police Chief Steve Bracknell. For the time being, "domestic violence can't be invoked because she has changed her story and says she didn't see a firearm," Bracknell said. On the 911 call, Shellie Zimmerman is sobbing and repeating "Oh my God" as she talks to a police dispatcher. She yells at her father to get inside the house, saying Zimmerman may start shooting at them. He's threatening all of us with a firearm ... He punched my dad in the nose," Shellie Zimmerman said on the call. I don't know what he's capable of. I'm really scared. Her father also declined to press charges, the police chief said. Police officers could still build a case based on surveillance video from cameras outside the house and also video from the squad cars of officers who responded. Florida law allows police officers to arrest someone for domestic violence without the consent of the victim.
