Some people are famous more for infamous acts than for any talent or skills they possess. This series documents people who are household names because of murders they have committed. Jodi Arias, Erik and Lyle Menendez, Ted Bundy and Drew Peterson are among the killers profiled in the hourlong episodes. Personal accounts from victims' family members, jurors, law enforcement officials and journalists involved with each case help provide an insiders' perspective and disclose new information about what transpired. Veteran crime reporter Steve Helling serves as a commentator for each episode, offering his insights into each case.
