The recordings were from interviews with Lee Anthony, Caylee's uncle, and Jesse Grund and Anthony Lazzaro, former boyfriends of Casey Anthony, the missing girl's mother.

Lee Anthony told investigators that his mother, Cindy Anthony, and his sister, Casey Anthony, had an ongoing feud that dated back to before Caylee was born.

In the interview, Lee Anthony described his sister's car, which had been returned to his parents' home July 15 after being found abandoned at an Orange County Amscot and towed to a lot.

"The trunk was open. The windows were rolled down to what I assume ventilate the horrible smell that I had just smelled for the first time," Lee Anthony said.

An investigator asked if the smell "filled up the garage."

"Yeah, it was ... it hit you like a wave. I mean it was -- whatever it was -- it was very potent," Lee Anthony said.

Lee Anthony said his mother grew tired of asking Casey Anthony questions about Caylee's whereabouts and getting no answers.

Lee Anthony said he then sat down alone with his sister.

"What's going on?" Lee Anthony asked Casey Anthony. "That's when she opened up to me and said, 'Mom has thrown it in my face many times before that I'm an unfit mother, and you know, maybe she's right and maybe I am.'"

Lee Anthony told his sister that she needed to start providing answers because their mother threatened to call police.

"The officer is going to say, you know, 'Good evening, Mrs. Anthony. Where's your daughter?' And she says, 'She's with the nanny. She's sleeping.' And again, playing the role of police officer, I say to my sister, 'Great, Mrs. Anthony. That's going to be a relief to everybody. Let's go get her,'" Lee Anthony said.

Lee Anthony also told investigators that his mother and sister were fighting about things other than Caylee.

"They're fighting about this stuff in the past instead of trying to focus on the information that we need to get," Lee Anthony said. "My mom is convinced that my sister holds some kind of resentment to her."

Transcripts of the interviews were released earlier this week.

Also, Local 6 News reported that more evidence against Casey Anthony, who was charged with child neglect in the disappearance of Caylee, will be released on Friday by the state attorney's office.

The information will include a videotaped statement given by Cindy Anthony, a computer forensics report and phone records of Casey Anthony.

'Babysitting Service' Mocks Protesters

Meanwhile, an outdoor "babysitting service" set up near the Anthony's home mocked protesters who continue to bring their young children, even infants, to heckle the family.

Local 6 videotaped a man taping signs to a baby's playpen reading, "Protesters Babysitting Service."

Homeowners have accused protesters of bad parenting for bringing infants and young children to the Anthony's Orange County home -- even late at night.

The home has become a tourist attraction for some visitors to Orlando and at least one group planned a trip to see the home after Casey Anthony was released from jail for the third time.

Recently, children were videotaped holding death signs in their parent's arms outside the Anthony home.

The protesters did not like the "babysitting service" and mocked the man setting it up, Local 6 reported.

Casey Sent 553 Text Messages

A a series of more than 550 text messages sent by Caylee Anthony's mother reveal the woman did not appear to be worried about her daughter in the days the girl was missing.

According to cell phone documents, in a two-month period between April and June, Casey Anthony sent her friend Amy Huizenga 553 text messages.

Of the messages, only two references are made to Caylee.

On May 13, Casey Anthony sent a text message that said, "My mom is taking the kid for the weekend for part of her vacation (with a smiley face)."

Then, less than a week before the toddler's disappearance, Casey Anthony announced, "Caylee just pooped in her potty for the first time. Sorry, proud mama."

The message was the last time Casey Anthony mentioned her daughter to Huizenga in text messages.

A week after the toddler vanished, Anthony sent a text to Huizenga that said, "Leaving for work in a few. I'll call you on my way to the house."

Casey Anthony did not have a job at Universal Studios or apparently anywhere else, Local 6 has learned.

On June 26, Casey Anthony wrote, "I need a freaking vacation."

The next day, a text message told Huizenga about how her car smelled like a dead animal -- and how it was possibly a squirrel that was run over.

Fifteen minutes later, Casey Anthony wrote, "My car ran out of gas again. Two weeks in a row. On Friday, my stupid car runs out of gas. Wow."

It now appears that Casey Anthony stole the gasoline cans from her father's back yard shed after she ran out of gas for the first time, Local 6 reported.

George Anthony seized the cans back from Casey Anthony.

Then, her vehicle's tank ran dry again, forcing her to abandon the car at an Amscot.

Two days later, on June 29, Casey Anthony sends a message to Huizenga," Can I borrow you and your gas can today?"

By that time, the car had already been towed.

Anthony told Huizenga that her father had picked up the car, which was not true, Local 6's Mike DeForest said.

Gonzalez Hires Prominent Attorney

Meanwhile, the woman who Casey Anthony claims to be Caylee's nanny, Zenaida Gonzalez, has hired a prominent Central Florida attorney.

Gonzalez told Local 6 that John Morgan is representing her in a lawsuit against the Anthony family.

Gonzalez said that since her name made national news, she's been unable to get a job and that being associated with Caylee's disappearance has ruined her reputation.

Gonzalez's attorney will press on with a defamation lawsuit because the sheriff's office has cleared her name.
