of murdering her 2-year-old daughter Caylee
, but a new movie is set to examine the case through the eyes of a man who believes she escaped justice.

The film would tell the story of the three years Ashton and his team spent preparing and prosecuting the Florida woman in a high-profile case

"I have seen my share of liars, but never one quite like this," Ashton writes, according to the Orlando Sentinel
Fox TV Studios has optioned the rights to the book, though Lifetime hasn't given the green light to the film yet, Variety reports.
