ORLANDO, Fla. -- Since her release from jail, Casey Anthony has been: A) sipping iced coffee and shopping at an Old Navy store near the Ohio State campus, B) camped out in a Florida Panhandle beachfront rental home, C) running from a private jet in Orlando with her head covered by a jacket, D) none of the above.

While the whereabouts of the mom acquitted of killing her toddler last month have become a national parlor game, one thing is certain: She wasn't in a Florida courtroom Friday when a judge heard arguments about whether she must return to Orlando to serve probation. Her lawyers have not disclosed where she is.

Judge Belvin Perry will decide next week whether Anthony must return. Until then, her location is anyone's guess.

When Anthony was released in the overnight hours of July 17, a sport utility vehicle whisked her and attorney Jose Baez away to a parking garage as television news helicopters followed. But the trail was lost as car after car left a garage with no sign of Anthony.

Speculation surrounded a twin-engine private jet headed for Columbus, Ohio, since Anthony was born in the Buckeye State and has relatives there. But when it landed, she did not exit.

Anthony next was reported to be staying at a beachfront rental home on St. George Island, Fla. A nearby airport had been one of the stops for a small plane that left the Orlando Executive Airport a few hours after Anthony's release, but reporters who knocked on the rental's door were greeted by a vacationing hardware store owner and his wife.

Other reports had Anthony boarding a plane owned by her ex-attorney, Todd Macaluso. That plane returned to Orlando a few days after Anthony was set free and a local television station broadcast images of a woman running from the aircraft. The woman wore clothes similar to what Anthony had on when she was last seen. Baez put out a statement saying it was a hoax. "Macaluso having fun with you," he texted a reporter at the TV station.

The Ohio rumors have persisted.

Last month, chief deputy Scott Hildenbrand of the Geauga County sheriff's office in Ohio squashed rumors that authorities provided Anthony a police escort for moving vans and protected her at a secret location in the northeast part of the state.

This week, TMZ posted images on its website of a woman who resembles Anthony strolling down a street near Ohio State, sipping an iced coffee and briefly looking at dresses at an Old Navy. The woman wore glasses and a bright red Ohio State ball cap, offending some ardent Buckeye fans.
