Air sample tests from Casey Anthony's car show a decomposing body was inside the trunk, a sheriff's office official just confirmed.
Officials have offered Anthony a partial immunity deal if she admits 3-year-old Caylee Marie died as a result of an accident.
Investigators with the Orange County Sheriff's Office are at defense attorney Jose Baez's Kissimmee law office. Anthony left Baez's office at 3 p.m., shortly after investigators arrived.
Anthony, wearing sun glasses and a t-shirt depicting her missing daughter, said nothing as she got into the back of a van and drove away with a bounty hunter.

Meanwhile, California bounty hunter Leonard Padilla said Anthony has made no effort to help him find Caylee, he told the Orlando Sentinel on Wednesday.
"She has not communicated with us at all," Padilla said. "She has no interest in communicating with us."
Padilla, whose nephew posted Anthony's $500,200 bail last week, said if he knew what he knew today about the case, and that the 22-year-old wouldn't cooperate with him, he probably would not have helped get her out of jail.
Padilla said he still thinks Caylee is alive and that Anthony handed her off to someone. But he does not believe the toddler was dropped off with a baby-sitter named Zenaida Fernandez-Gonzalez, which is what Anthony has told detectives.
"We don't believe [Zenaida Fernandez-Gonzalez] exists," Padilla said.
"[Anthony's] got an invisible friend that's called Zenaida," he said. "She's got a world that she lives in that's apart from ours."
Padilla said he is using Anthony's cell phone records as part of his own investigation and has spoken to some of her friends.
