Retired Florida prosecutor Jeff Ashton calls the trial arguments of Casey Anthony's defense team, which resulted in an acquittal
for the accused murderer
, "a complete crock of crap" in a new book published Tuesday.
"I've written a book to let people know the truth about the case from my perspective," Ashton tells the Orlando Sentinel
of Imperfect Justice, Prosecuting Casey Anthony
In the 322-page book, the paper reports, the lawyer writes that once her trial was underway Casey told two mental health professionals that her 2-year-old daughter
Caylee had drowned in the family swimming pool – deliberately killed by Casey's father, George
She also told the experts that her father molested her and she feared a similar fate awaited Caylee.
"I have seen my share of liars, but never one quite like this," Ashton writes in the book, according to the Sentinel
. Later he states, "In many ways, I think the defense came to mirror the client they represented."
In its report on the book, Central Florida's News 13
quotes Ashton as saying that the introduction of the death penalty in the case was not a good idea, because the jury would never go for it.
Of Anthony's defense attorney, Jose Baez, Ashton writes, as quoted by the Associated Press: "There is an unearned air of arrogance about the man that is incredibly frustrating to witness. The word I used in describing Jose is smarmy: somebody who is slick, underhanded and doesn't shoot straight."
Ashton writes that he felt numb when the verdict was delivered, and he dedicates his book to Caylee, "so no one forgets."
