Investigative interviews with Casey Anthony's friend Amy Huizenga and boyfriend Tony Lazarro reveal new information about the woman's activities.

Huizenga told investigators, "I know she has started smoking more pot than she ever had. She would eat a brownie here or there (and) maybe smoke every once in a great while. Um, but she did tell me that she'd been smoking a lot more pot."

Huizenga's statement about Casey Anthony referred to mid-June -- around the time Caylee was last seen.

A few weeks later, around the first week in July, Casey Anthony told Huizenga that Caylee was with her nanny at Sea World.

An investigator asks, "She had her nails done that week?"

"Yeah, I'm pretty sure she had those done on that Tuesday," Huizenga said.

The next day, Casey Anthony got a tattoo on her shoulder that read "Buena Vita" -- which means good life, Local 6 reported.

"So, she got her fingernails cleaned, done up pretty and a tattoo in the week that Tony's gone?" the investigator asked.

"Uh-hum," Huizenga said.

"And goes out partying (July 2 and 3)?" the investigator asks.

"And the fourth," Huizenga said.

"The fourth?" the investigator asks.

"Because we had a July Fourth party," Huizenga said.

In his interview, boyfriend Tony Lazzaro revealed that in the second week of July, after he returned from a trip to New York, he said he and Casey Anthyony and friends watched a UFC fight at a local restaurant and went grocery shopping the next day.

That was a week before Casey Anthony was arrested for the first time.

According to her friends, Anthony did not express concern about her daughter.

Also, after July 5, Casey Anthony would wake up sweating in the middle of the night, saying she was having nightmares.

Death Smell Sparked Concern

Nearly three weeks before deputies arrested Casey Anthony, the 22-year-old admitted to a friend that her car smelled like death, the documents showed.

In a phone call to Amy Huizenga, Casey Anthony told her friend, "It smells like something died in my car."

Casey Anthony claimed her father, George, had possibly run over a squirrel when he borrowed her car that week.

However, the date would have been during a period when the Anthonys said they could not find Casey Anthony.

Also, on June 27, documents show that Casey Anthony sent a cell phone text message to her friend (Amy Huizenga) that reads, "There was definitely part of a dead animal plastered to the frame of my car."

According to Huizenga, June 27 is the date when Casey Anthony admitted leaving her car at an Amscot, claiming it had run out of gas.

The car was later towed to an impound lot, where George and Cindy picked it up two weeks later.

Cindy Anthony initially told a 911 operator, "There's something wrong. I found my daughter's car today and it smells like there's been a dead body in the damn car."

Cindy Anthony later claimed the smell was rotting pizza.

But according to Huizenga, from the very beginning, Cindy Anthony apparently suspected foul play, Local 6 reported.

As Amy Huizenga and Cindy Anthony were driving around town looking for Casey, Cindy Anthony wondered if the foul odor was connected to her daughter and granddaughter.

Huizenga said, "They were afraid it was either Caylee or Casey stuffed in the trunk."

Mom-Daughter Feud Discussed

The documents also included information about Lee Anthony voluntarily sitting down with detectives and remembering vivid details about the night he discovered his niece was missing.

He told detectives that his mother and sister have had an ongoing feud that started before Caylee went missing.

On the night of July 15, Cindy Anthony finally tracked down Casey and retrieved her white Pontiac from an impound lot.

When Lee Anthony made it to the family home, he said the smell from the car was overwhelming.

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

The investigator said, "The smell filled up the whole garage?"

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

According to the interview that Lee Anthony gave detectives, Cindy Anthony grew tired of questioning her daughter about Caylee's whereabouts and getting no answers.

She eventually sent Lee Anthony to try to make some ground with Casey.

While Lee Anthony was alone with his sister, he said, "What's going on (and) what is the deal?" 'That's when she 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."

After interrogating her daughter and still not getting what she thought was a straight answer, Cindy Anthony threatened to call police.

Lee Anthony talked to Casey and told her she needed to come clean before detectives arrived.

He played the role of a police officer, saying, "The officer is going to say, 'Good evening, Mrs. Anthony. Um, where is your daughter?' And she says, 'She's sleeping.' And again, playing the role of the police officer, I say to my sister, 'Great Mr. Anthony. That's going to be a relief to everybody. Let's go get her.'"

The detectives then told Lee Anthony, "You just gave her a slap of reality."

Lee Anthony replied, "exactly."

Later, Lee pointed out to detectives that his mother and sister have always had a rocky relationship.

He also said that in the middle of Cindy Anthony trying to get answers about Caylee they were fighting.

"They were fighting about this stuff in the past instead of trying to focus on the information that we need to get," Lee Anthony said.

"There is a genuine wedge between your mother and your sister, isn't there?" an investigator asked.

"My mother has been the provider for Caylee, even down to the extent that my mother was the first person to hold Caylee when she came out of the womb. So, my mom is convinced that my sister holds some kind of resentment to her."

The documents were released as a part of the discovery process, where the prosecution is required by law to hand over to the defense all of the evidence they may be using in the trial against Casey Anthony, who was charged with child neglect in mid-July, about a month after she said she last saw her daughter.

Once the documents are released to the defense, they are made a part of the public record and released to the media, Local 6 News reported.

About a month ago, 400 pages were released in the case, including interviews with friends of Casey Anthony.

Deputy Assigned To Home?

Orange County Commissioner Mildred Fernandez said she will request that a deputy be assigned to the Anthony home on weekends as protesters continue to demonstrate.

Several fights, scuffles and arguments have broken out at the home -- mostly on the weekends -- prompting numerous 911 calls to the home.

Fernandez said the request would be made as a last resort if a lawsuit filed by the neighborhood's homeowners association fails.

A search continues for Caylee.
