Police said they also found no signs of "trauma, redness, or marks of any kind" in the area where her father, David Dean, said he was struck. Police added that "none of the witnesses to the event could corroborate ... [the] account of the battery."
Sims today released a photo of David Dean purporting to show a mark on his nose after the disturbance.
George Zimmerman told police that he came to the home to ensure that his wife was getting the property agreed upon by their attorneys.
Shellie Zimmerman told police her husband stuck his arm inside her father's truck and she told him that he was not allowed inside. A dispute ensued and she claimed he grabbed the iPad.
After destroying the device, George Zimmerman reached his hand into his shirt to what she "assumed was a gun," she told police, adding that George Zimmerman told her father to "step closer."
She said her father then told her husband, "What are you going to do, shoot me?"
Samantha Schelbe, who was in the passenger seat of George Zimmerman's car, was "visibly shaken" by the ordeal, police said. Schelbe told police George Zimmerman never touched anyone and said that there were guns in the vehicle but that they had concealed weapons permits for them.
Neither Shellie Zimmerman nor her father said they actually saw a weapon, according to the police report.
George Zimmerman's attorney said soon after the incident that he would no longer represent the client he helped acquit in the death of teenager Trayvon Martin in new legal matters, including his upcoming divorce.
