Investigators released text message and voicemail transcripts, interviews and other evidence documents Friday in the case of a missing Florida toddler.

Authorities from the Orange Osceola State Attorney's Office made the additional pages of discovery — which also include depositions, photos and an interview with little Caylee Anthony's grandmother — available to the public Friday, MyFOXOrlando.com reported.

On Thursday night, the Orange County Sheriff's Office released audio recordings of interviews with people connected to the child's mother, Casey Anthony, who is considered a person of interest in her daughter's disappearance.

The interviews are with Anthony's most recent boyfriend Anthony Lazaro, her former fiance Jesse Grund and her brother Lee Anthony.

Meanwhile, a woman filed a defamation lawsuit against Casey Anthony, saying she was accused by the 22-year-old mother of kidnapping Caylee.

Zenaida Gonzalez has never met Anthony, according to her attorney John Morgan. He said Anthony accused Gonzalez of taking her daughter in June. Gonzalez sued Anthony Wednesday in Orlando.

Anthony says she last saw Caylee, whose third birthday was Aug. 9, with a babysitter named Zenaida Gonzalez in June. Authorities don't believe her.

Todd Black, a spokesman for Anthony's attorney, said this isn't the same Zenaida Gonzalez Anthony left her child with. Black called the lawsuit frivolous.

Anthony has been charged with child neglect, making false statements and obstruction. She contends she doesn't know what happened to Caylee.

Also this week, Anthony said she believed a strong odor in her car came from a dead squirrel, recently released documents show.

During a police interview, her friend Amy Huizenga said Anthony told friends her car smelled like something had died and theorized that her father had run over an animal.

Police said earlier this month that there was evidence of a decomposing body in the trunk of her vehicle.

Anthony also faces unrelated check fraud charges and is currently at home with her parents on house arrest after several stints in the Orange County Jail.
