The movie is based on a true crime case and the real names were used for three of the main four characters - all except Dave's ex-wife whose real name is Amy Flora. Her name in the movie is Sarah Brower, but when the detective called Dave, near the end, when Liz was in his apartment, he told Dave that "Amy was seen by a neighbor the night of the shooting so she's cleared". The same detective pronounced Cari Farver's name as "Ferver" when he was explaining to Liz the evidence against her near the end.
