Where in the world is George Zimmerman?

(HLN) -- George Zimmerman is nowhere to be found, according to his estranged wife's attorney.

Shellie Zimmerman is trying to divorce the man who in July was acquitted in the shooting death of 17-year-old Trayvon Martin, but can't locate Zimmerman to serve him with legal documents.

Zimmerman's disappearance comes two weeks after police responded to a "domestic altercation" at a Florida home owned by his father-in-law, David Bryant Dean.

Shellie Zimmerman's attorney, Kelly Sims, told CNN that he isn't shocked by Zimmerman's disappearance under the circumstances.

"We don't know where he is, but that's neither surprising or unusual. I'm sure when the time is right we will serve him, and there is no indication that Mr. Zimmerman is actively avoiding same. A little space and time between the couple just makes sense," said Sims.

Zimmerman is not facing any legal ramifications from the domestic dispute as of now, but police say it may take months for investigators to decide whether charges will result from the incident.

Shellie Zimmerman called 911 from the house in Lake Mary owned by her father during a confrontation with her husband on September 9.

"He's in his car and he continually has his hand on his gun saying 'step closer' and he's going to shoot us," she told the dispatcher. Shellie Zimmerman told police her husband smashed her iPad during the dispute.

Zach Hudson, spokesman for the Lake Mary Police Department, said charges will not be filed until investigators can recover video from the iPad.

"The iPad is in really bad shape," Hudson said. "It could take weeks or months to get video off the iPad."
