NBC's Today show reported Tuesday that Anthony -- whom a jury recently found not guilty of murdering her 2-year-old daughter, Caylee -- could be staying outside San Diego in Carlsbad, Calif.

NBC News claimed to have tracked the ownership of a private jet that is said to have carried Anthony out of Orlando an hour after her release early Sunday. The news organization claimed that it is registered to California lawyer Todd Macaluso, who previously represented Anthony and whose firm has an office in Carlsbad.

Anthony's attorney, Jose Baez, later sent a text message to a reporter that read, "That is not Casey. … Macaluso is having fun with you and I had no knowledge of that."

Anthony's whereabouts have remained a mystery since her release from jail. Many who have been following the 3-year-old case -- including HLN's Nancy Grace -- are still insisting she is guilty.
