Many around the world were glued to the news as they watched Casey Anthony stand trial for allegedly killing her two-year-old daughter, Caylee Marie. As the trial went on, many got to know her lawyer, Jose Baez. When Anthony was not convicted of murder in 2011, many were shocked and Baez became a sort of celebrity.

Now, Baez has released a tell-all book about his experiences during the Casey Anthony trial and writes that investigators should have known his client had “serious mental health issues.”

According to the Associated Press, Baez’s book, Presumed Guilty, Casey Anthony: The Inside Story, reads detectives investigating Anthony should have identified that she was living in “a fantasy world,” especially after she took them to Universal Studios where she pretended to work.

Baez writes:

[They] should have stopped and realized, ‘Wait a minute, we’re not dealing with someone who is playing with a full deck.

Presumed Guilty, Casey Anthony: The Inside Story will be available in bookstores on July 3, one year after Casey Anthony was found not-guilty of murdering her daughter.

In May, Baez told People, “Casey will not financially benefit from this book in any way, shape or form. This is my story, not hers.”
