Blood Brothers (2015)

Blood Brothers, based loosely on the famous Leopold and Loeb murder case, tells the tale of Charles Brubaker and his half-brother Thomas Lo Bianco, who concoct a deadly game to test their superior intelligence against the dimwitted masses.

This game will eventually lead to murder, but problems arise when they quickly discover that Detective Homer Gaul, a cop with a very special gift, is hot on their trail.
