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."
She also said he grabbed an iPad from her hand and smashed it.
Zimmerman's attorney, Mark O'Mara, said his client never threatened his estranged wife and her father with a gun and never punched his father-in-law. Shellie Zimmerman had collected most of her belongings Saturday from the house, which is owned by her parents, where she and George had both been staying until she moved out. She had returned unexpectedly Monday to gather the remaining items. Emotions got out of control, O'Mara said, but neither side is filing charges against the other.
"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, the police chief said.
Prosecutors 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.
Hudson said the estranged husband and wife were blaming each other for being the aggressor and that police officers were sorting through their accounts.
In her divorce filing last week, Shellie Zimmerman said she and her husband had separated a month after he was acquitted of any crime for fatally shooting the 17-year-old Martin in Sanford, not far from where Monday's investigation happened.
