Shellie Zimmerman filed for divorce last week. She and her husband separated a month after he was acquitted July 13 in the fatal shooting of 17-year-old Trayvon Martin.
The encounter Monday was the latest in a string of events for Zimmerman. He has twice been pulled over on suspicion of speeding and ticketed once. He also appeared in photos at a gun maker that were published online and he helped members of a family from their vehicle following a car wreck.
Shellie Zimmerman had collected most of her belongings from the house where she and her husband had been staying until she moved out. On Monday, she returned unexpectedly to gather the remaining items, and emotions got out of control, O'Mara said. Police talked to everyone about what happened, but neither side pressed charges and no one was arrested.
"I know the 911 tape suggests that Shellie was saying something but I think that was heightened emotions," O'Mara said. "There may have been some pushing and touching. That happens a lot in divorce situations. . . . Nobody was injured."
Her father also declined to press charges.
George Zimmerman's brother Robert Zimmerman Jr. tweeted after media reports surfaced about the dispute 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."
Authorities are also looking into whether surveillance video from cameras at the house captured the dispute. Also, Shellie Zimmerman said on the 911 call that a city worker witnessed it, and if so, that eyewitness could help authorities decide whether to file charges.
Florida law allows police officers to arrest someone for domestic violence without the consent of the victim.
