BBM. For the record, Ashton's book was as "ghostwritten" as Baez's. "Imperfect Justice" was co-written by Lisa Pulitzer, a former New York Times correspondent who has written other true-crime books, including "Portrait of a Monster," about Joran van der Sloot, a suspect in the 2005 disappearance of American Natalee Holloway in Aruba.
Not only that, based on the speed it was written, IMO, he was writing the book before and during the trial itself, while he was being paid by the State of Florida to prosecute Casey Anthony.
Jeff AShton retired from public service at the end of the trial - July 2011.
He announced in August that he was writing a book about his career and his part in this trial. I don't recall seeing him doing other than appropriate work in Court ( as opposed to Baez who treating the court with contempt and was having fun and games with Casey) and he presumably had days off and weekends off to compose his book if he was even doing it then.
