Hundreds of pages of documents were released Friday in the discovery phase of the first-degree murder case of Casey Anthony.

Anthony remains jailed on first-degree murder charges in the death of her daughter, Caylee, whose remains were discovered in December. Caylee was 2 years old when she was reported missing in mid-July, about a month after she was last seen alive.

The documents included transcripts of several conversations between investigators and people who knew Casey Anthony, including one with her maternal grandmother, Shirley Plesea, which took place in August 2008.

Plesea described the instances when Casey Anthony stole money from her and goes into detail about Cindy Anthony's relationship with her daughter and her granddaughter.

When Plesea discovered her granddaughter had stolen from her for a second time, she told detectives she wanted Casey Anthony sent to jail.

"I told them to go ahead and arrest her," Plesea told investigators.

When it came to the relationship between Casey and Cindy Anthony, Plesea told investigators there was tension and that Cindy Anthony had threatened to take custody of Caylee.

"She (Cindy) would give her life for Caylee," Plesea said. "If she could not believe Casey, believe in Casey, she'd have to accept that fact that Caylee might be dead, or would be dead, or whatever."

"I don't not want to think that Casey -- or that Caylee -- isn't alive, but I just wondered if she (Casey) hated her mom more than she loved Caylee," Plesea said.

At the time, months before Caylee's remains were discovered, Plesea said it would take something drastic for Casey Anthony to be honest about what happened to Caylee.

"She probably needs somebody to threaten her, personally. You know I hate to think of her being put in jail with them women that's going to beat the hell out of her, but it might do her some good," Plesea said.

The documents also included a transcript of a conversation between Detective Yuri Melich and Cameron Campina. Campina lived with Anthony Lazzaro, Casey Anthony's ex-boyfriend. Casey Anthony stayed with them beginning in June 2008.

Campina told detectives he sometimes sold marijuana and Xanax but only ever saw Casey Anthony smoke marijuana. He said when he asked about Caylee, Casey Anthony told him Caylee was at a birthday party in Cocoa Beach and staying with friends.

Meanwhile, Anthony turned 23 years old on Thursday, a birthday she spent almost entirely in her 12.5-by-7-foot cell.

CASEY ANTHONY TURNS 23: |

Anthony had a visit scheduled with her lawyer on her birthday, but it's not known if they met. Inmates receive no special treatment on birthdays or anniversaries, and Anthony will spend about 23 hours in her cell.

Anthony's family has avoided meeting with her because the visits are recorded and released to the public as part of the discovery process.

In a past birthday, Internet photographs show Casey Anthony wearing a tiara and celebrating with her brother, Lee Anthony.

At a memorial service for Caylee in February, Anthony's father, George Anthony urged the public to reach out to his daughter.

"She deserves letters. Take the time to write a letter to her. Just say, 'Hi Casey, I'm thinking about you today," George Anthony said.

Casey Anthony's attorney screens her mail, however, and it's not known how much, if any, is passed on to her.

The Anthony family celebrated Caylee's August birthday without Caylee being present, and now will do the same with Casey Anthony.

"Our emotions are really tough right now because tomorrow's a big day, and every day that gets closer to her birthday gets harder," said Cindy Anthony, a day before Caylee's third birthday.
