The Florida State Attorney's Office released about 5,000 pages of information related to the Casey Anthony case on Friday, including dozens of letters she received in prison, among them fan mail and notes from her father, MyFoxOrlando.com reported.

Each page of information can be used as evidence in the 24-year-old Floridian's capital murder case. Anthony is charged with first-degree murder in the 2008 death of her 2-year-old daughter, Caylee Anthony.

Casey Anthony's father, George Anthony, expressed how much he missed his daughter in his letters.

"I hope and pray every day that you are doing alright," George Anthony wrote to her in November 2008. "You are my family no matter what."

In February 2009, a woman from Tennessee wrote to Anthony: "I am going to send you some money in the next few weeks.... If the media wants to hunt me down and ask why, I'll say because I believe in you.... You have a friend whom you have never met who believes in you."

Many letters express support, share prayers and Bible passages and include money or a promise of a financial donation to Anthony.

Another stranger writes: "Hey there, my name is Jovert, people just call me Joe though. I'm writing just to see how you're holding up, don't worry this isn't a hate letter or anything of that sort."

Not all the letters Anthony received were so supportive.

One stranger writes: "I would watch you (on TV) and get so angry because I could not figure out how you could be so cocky when I just knew you took your daughter's life."

Anthony's murder trial begins on May 9, 2011.
