Casey Anthony -- Double Secret Probation

Casey Anthony is still living in fear of death threats ... and the Florida Department of Corrections has announced it will keep all of Casey's probation information CONFIDENTIAL in an effort to keep her safe.

The FDOC released a statement to TMZ saying, "The court has directed us to keep confidential the offender’s residence or any information that could lead to the discovery of her location because of the death threats against her."

The statement continues, "Therefore, she will not be identified in our database, nor will her probation officer’s name or probation location be made public."

As we previously reported, this morning Anthony checked in to serve probation for her check fraud conviction.
