Orange County corrections officials confiscated a greeting card mailed to Casey Anthony by her mother because the envelope improperly suggested it contained confidential legal documents.

For security purposes, Orange County Jail workers routinely screen mail sent to inmates. But corrections officers are not allowed to look at letters inmates receive from their lawyers, which are generally protected by attorney-client privilege.

In May, employees in the jail's mail room intercepted an envelope addressed to Casey Anthony which was labeled "Legal Mail - Do Not Open". The type-written return address suggested the letter had been mailed from the Kissimmee office of Casey Anthony's attorney, Jose Baez.

Corrections officials told Local 6 the envelope looked suspicious, so two officers hand-delivered the correspondence to Casey Anthony's jail cell and watched her open it.

Instead of confidential legal documents, the envelope contained a greeting card signed by Anthony's mother, Cindy. "I love you and miss you," the card stated. "You were a great mother to Caylee."

Corrections officials confiscated the contraband and returned the card to Casey Anthony's attorney, according to a jail spokesman.

Jose Baez told Local 6 the card was not sent from his office.

Cindy Anthony's attorney, Brad Conway, said he was unaware his client had sent a card to her daughter.

Two weeks after corrections officials confiscated the greeting card, Cindy Anthony mailed a letter to her daughter. The family's home address was printed on the envelope.

"So I understand the jail (thinks) I committed mail fraud," the letter states. "They must think I'm really STUPID. Why would I send you a card and put another address besides mine on it? What purpose would that serve? None!"

Orange County corrections officials have not publicly accused anyone of mail fraud, and no investigation will be conducted, according to a jail spokesman.

Casey Anthony, 24, is jailed on first-degree murder charges in the death of her daughter, Caylee, whose remains were found in December 2008. Caylee was 2 years old when she was reported missing about five months earlier.

Casey Anthony has pleaded not guilty, and her trial is scheduled to begin in May 2011.
