Serial killer characters have only become more prevalent on TV over the past few years, and the phenomenon doesn't appear to be slowing down any time soon. In 2013, seven new shows focusing on cutthroat criminals debuted and 2014 brought an audience obsession with HBO's "True Detective." The latest to jump on the trend is "Aquarius" (premiering May 28 on NBC), which stars David Duchovny as a cop investigating Charles Manson in the '60s.

Check out seven of the hottest serial killers in TV history.
