Casey Anthony has been in prison since 2008, charged with the death of her 2-year-old daughter, Caylee. During that time, she has not taken or received a single phone call (except from her attorneys). Now it's been revealed that Anthony has been engaging in correspondence with fellow prisoners -- correspondence that includes almost 300 pages of handwritten notes. Normally, letter-writing in prison is no big deal -- but in this case, Anthony is being held in protective custody, which restricts her from contacting any of her fellow prisoners.One of her pen pals is Maya Derkovic, a woman convicted of second-degree murder. Derkovic told authorities that Casey had informed her that she used to "knock out" Caylee so she could go out and party. That confession, however, is not present in any of the correspondence. Derkovic, who is serving 30 years, spent time in a jail cell near Casey. She and Anthony also exchanged letters with three other prisoners.
The release of these letters has raised questions of jailhouse security. "While there is no way to prevent inmates in adjacent cells from having fleeting communications, the passing of notes is something that would not be permitted," jail spokesman Allen Moore said.
