Hennessy chose not to renew her three-year contract at the end of season 6 to pursue other projects, and Claire Kincaid was written off as being killed in a drunk driving accident. She was replaced by Carey Lowell as Assistant District Attorney Jamie Ross. Lowell remained with the show until the end of season 8, when she left to spend more time with her daughter. (Jamie Ross was written off as leaving the D.A.'s office for similar reasons.) Lowell (who later returned for a couple guest appearances) was replaced by Angie Harmon as Assistant District Attorney Abigail "Abbie" Carmichael, who was conceived as being much louder and outspoken than any of her predecessors. Harmon auditioned with 85 other women, including Vanessa Williams, for the role, and was picked after Wolf heard her Texas accent.
