UPDATE ADDED Remains Found with Duct Tape on Mouth; Casey on Psych Watch, In Isolation

Reports from NBC News state that the utility worker that went into the woods and stumbled upon the bag. Upon using a stick to poke at the bag, a skull became visible and had duct tape on the mouth.

DNA from the remains will be compared to Caylee's DNA at Quantico, VA. When Jose Baez told Casey of the news, she began to sob.

Prosecutors tell NBC News that even though they had pulled the death penalty off the table, that could change.

According to Sheriff Kevin Beary, there are clues that came out of the bag yesterday that led them to obtaining the search warrant last night and secluding the Anthony home.

Casey is on Psychological Watch and is in isolation at the Orange County Jail.

*Update: Theories are that the duct tape found over the mouth on the skull could have been used to "stage" a kidnapping, or used in the actual death. Duct tape and garbage bags are excellent items for forensic evidence. They can contain trace evidence, such as on the duct tape, it can collect fingerprints, fibers, hair, etc.
