Later that season, Martin departed early to film "Rent." Ed Green was temporarily written off as being shot in the line of duty and being replaced during his recovery by Detective Nick Falco, played by Michael Imperioli, who had previously guest starred as a murder suspect in the season 6 episode "Atonement". Parisse left the series at the end of season 16 (with ADA Borgia written off as being murdered), and Farina announced shortly afterward that he too was leaving "Law & Order" to pursue other projects. (Detective Fontana was written off as having retired off-screen.)
