Cops: Casey Anthony Told Inmate Too Much About Caylee's Remains

April 7, 2010 — -- Casey Anthony knew details about her 2-year-old daughter Caylee Anthony's remains before they were made public knowledge, according to a police interview with a fellow inmate of Anthony's.

"After a chaplain informed Casey Anthony of the recovery, Casey Anthony told [inmate] Robyn Adams law enforcement had found the body of a small child with a baby blanket inside a black garbage bag," police said in the witness report, which was included in hundreds of pages of documents released by prosecutors Tuesday.

"As a note, the information regarding the baby blanket and black garbage bag was not made known to the jail chaplain so Casey Anthony had knowledge of items only the suspect, certain law enforcement personnel and the certain medical examiner's personnel knew," the report said.

Anthony's conversation with Adams allegedly took place soon after Dec. 11, 2008, the day media outlets including ABC News reported a child's skull had been found by a utility worker less than a mile from the Anthony home.

The detail about the baby blanket did not come to light until the next month, when the state attorney's office released a report on items discovered with the remains.

Adams also told police that once when searchers previously thought they had found Caylee's remains but were mistaken, Anthony giggled "not like in an evil way ... like ... it's not my daughter," the witness report said.

But once the set of remains were found near her home, Anthony became terrified, Adams said. Those remains were later identified as Caylee's.

Casey Anthony is awaiting trial on first-degree murder charges in the death of Caylee and has been in an Orange County, Fla., jail since the summer of 2008. She has pleaded not guilty.
