George Zimmerman was being questioned Monday in Central Florida after his estranged wife called police saying he threatened her with a gun.

Lake Mary police say they were called around 2:to the Sprucewood Road home of Shellie Zimmerman's parents, David and Machelle Dean.

Lake Mary police spokesman Zach Hudson said police are "trying to determine what exactly happened."

According to Chief Steve Bracknell, Shellie Zimmerman called 911 claiming George Zimmerman had a gun and was making threats. The victims are not speaking to police and were waiting for their attorney to arrive, Bracknell said.

As of 3:20 p.m., no arrests have been made.

A spokesman for former Local 6 legal analyst Mark O'Mara, who represented George Zimmerman in his murder trial, said he had no comment at this time.

The incident comes days after Shellie Zimmerman filed for divorce and discussed her relationship with George Zimmerman on a TV interview.

Since being acquitted in the shooting death of 17-year-old Trayvon Martin, George Zimmerman has been pulled over twice for speeding, including once in Texas, in which he told officers he had a gun in the car.

Lake Mary is located about 20 miles north of Orlando and 5 miles southwest of Sanford, where Zimmerman fatally shot Martin.
