Jeffrey Dahmer, whose criminal "career" lasted over a decade, never shied away from his crimes after his capture. If anything, Dahmer openly admitted to a host of terrible things he did without a hint of shame.

The video here details how Dahmer disposed of his bodies. As can be expected, his methods are nothing short of horrifying, and his relative remorseless makes them even more chillingly upsetting.
But to Dahmer, such ghastly actions were all in a day's work.
