Law & Order: Criminal Intent S05E22 - The Good

In the season finale, after a suburban couple is found bludgeoned to death, Detectives Logan and Barek suspect that their drug-troubled son Kevin killed his parents' for their cash stash. But when a local investigator pressures the kid into a confession, the city cops discover a conflict of interest. While another suspect with close business ties to the victims emerges, Captain Deakins urges Logan and Barek to drop the non-jurisdictional case -- and ponders his own future with the NYPD.
