No Exit (S04E20)

Four young adults meet and are planning something - the fifth person, Carmine Ruggiero (David Jenkins), isn't there. They all reconvene and pick up Carmine, but unknown to him, they are on a suicide mission, parking their car in front of a train. Goren (Vincent D'Onofrio), investigating the crime scene, realizes from the glass under Carmine's foot that he was trying to escape, and they start to wonder if there's something suspicious going on there. In the meantime, Carmine's bosses at LongBridge Finance, Hubert Skoller (Arye Gross) and Leonard Timmons (Darrell Hammond), get the news about Carmine, which followed another recent suicide, of Edie Elverson. Initial investigation of the suicide leads the cops to a bizarre website, Terminal Decision, where Jules Smythe (Jason Antoon) runs a "how-to" suicide website. (iTunes)
