"The call went out as a 911 call that Mr. Zimmerman was threatening them with a firearm," Hudson said. "We're trying to see if that's true or not."
In her divorce petition, Shellie Zimmerman asked that her husband pay for a permanent life insurance policy with her named as the beneficiary, according to a divorce petition made public last week.
In an interview with ABC's "Good Morning America" that aired last Friday, Zimmerman said her husband left her with "a bunch of pieces of broken glass" after the acquittal. She said he only stayed in their house three or four nights since the trial ended and that they even tried counseling. But she moved out Aug. 13.
"I have a selfish husband and I think George is all about George," she said.
George Zimmerman and his lawyers have made no public statements on the divorce proceedings. An email to Zimmerman's lawyers weren't immediately answered. But lead defense attorney Mark O'Mara was at the home.
Neighbors and other onlookers gathered to watch.
George Zimmerman's brother Robert Zimmerman Jr., tweeted that "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."
Last month, Shellie Zimmerman, 26, pleaded guilty to a misdemeanor perjury charge for lying about the couple's finances during a bail hearing following her husband's arrest after Martin's shooting.
George Zimmerman, 29, said he acted in self-defense when he killed Martin and the polarizing case opened up national discussions on self-defense laws and race. Martin was black. Zimmerman has a white father and Hispanic mother.
Shellie Zimmerman was sentenced to a year's probation and 100 hours of community service. Her husband did not attend the sentencing hearing in the Sanford courtroom.
Zimmerman has been involved with a domestic case at least once before. In 2005, Zimmerman's former fiancee filed for a restraining order against Zimmerman, alleging domestic violence. Zimmerman responded by requesting a restraining order against his then-fiancee.
