True Confessions (2007)

In 1940s Los Angeles, Detective Tom Spellacy (Robert Duvall) probes into the savage murder of a woman found dumped in an empty lot. At the same time, he investigates a priest found dead in a whorehouse. Spellacy's brother (Robert De Niro), a Catholic priest, is meanwhile attempting to expand his church through Jack (Charles Durning), a shady contractor. While the two police cases and the real estate deal seem a world apart, Spellacy discovers an insidious connection involving money and power.
