( CNN ) -- The mother of child murder suspect Casey Anthony affirms her belief in her daughter 's innocence and expresses fear for her safety in letters released by court officials on Thursday . `` You stay strong Casey , '' Cindy Anthony tells her daughter in one letter from May . `` Many , many people believe in you and are trying to get to the truth . Not everyone has been brainwashed and not everyone is trying to cover his/her butt . '' Casey Anthony is charged with capital murder in the death of her 2-year-old daughter Caylee . The girl was reported missing in July 2008 , and investigators found her body after five months of intense searches and speculation . In the May letter , Cindy Anthony writes that she `` freaked out '' when she saw her daughter being escorted into the courtroom by heavily armed deputies . `` I was worried that there 's treats [ sic ] on your life and are finally being taken seriously , '' she wrote . `` I swear there are maniacs out there . I hope they step up security next year , for all of us . It 's going to be nuts . Hopefully by then somebody will actually look at the evidence and clearly see that they need to be looking for the real person that took our Caylee . '' In June , after Casey Anthony tripped on her way to a court appearance and showed up with a chipped tooth and cut lip , her mother said she had been `` worried that something was going to happen to you . '' She thanks her daughter for trying to call on Mother 's Day , and tells her , `` I had a dream the other night that you will be home . '' `` I know you better than anyone , '' Cindy Anthony wrote . `` Even with unanswered questions I still know the person you are and love you have in your heart . Your problem is that you are too trusting like I was . Unfortunately , we both found out how ugly and mean people really are . There 's very few people you can trust . '' The letters were released as part of discovery in the case . In June , prosecutors released more than 5,000 pages of documents that ranged from marriage proposals from admirers to calls for Casey Anthony to be put to death . She has pleaded not guilty and has refused to see visitors , because the sessions would be videotaped and eventually released . In a July letter , her mother laments , `` I just wish we had the ability to speak to each other . '' In Session 's Aletse Mellado contributed to this report .
