George Zimmerman's wife Shellie called Lake Mary Police Monday afternoon saying her spouse was arguing with her and her father, and that he had a hand on his gun, according to Police Chief Steve Bracknell.
Lake Mary police officers later said that Zimmerman did not have a gun during the incident and cops had not seen any firearm. Zimmerman was "free to go" after police questioned him at a home owned by Shellie Zimmerman's father, Lake Mary Police public information officer Zach Hudson told NBC News. Shellie Zimmerman and her father declined to press charges against her husband.
Police were dispatched to the home Monday afternoon to investigate a "possible domestic battery case."
Shellie Zimmerman's father had been hit in the face during an argument at the house, MSNBC's Craig Melvin reported. In a 911 call to police, 26-year-old Shellie Zimmerman is heard telling her father to get inside the house, "George might start shooting at us, I don't know."
"I don't know what he's capable of, I'm really, really scared," she later said to the dispatcher on the call.
Shellie Zimmerman turned in paperwork in court last week filing for divorce—just two months after George Zimmerman was acquitted of second-degree murder and manslaughter in the shooting death of Florida teen Trayvon Martin.
Zimmerman's brother, Robert Zimmerman, Jr. tweeted Monday afternoon for the public not to "jump to conclusions."
We've learned from GZ case not to "jump to conclusions", to wait for facts, & to avoid speculation. "News" is a business - not your friend.— Robert Zimmerman JR (@rzimmermanjr) September 9, 2013
