Warning: This video contains graphic descriptions of violence. Since our first episode, Inside Edition has gone inside the minds of some of America’s most ruthless killers, such as Jefferey Dahmer, Richard Ramirez and Jodi Arias. In each interview, the criminals discuss their motives and try to reason what horrific crime they had done. We also present the story of John Wayne Gacy who terrorized Illinois in the 1970s and 1980s. #InsideEdition
