Who is the deadliest serial killer in the U.S.? Ted Bundy? Jeffrey Dahmer? If those were your answers, you've got to listen to this one! Samuel Little is perhaps the deadliest American serial killer, with his number of victims reaching nearly 100 in total. In this episode, Kenna talks about Samuel's life, which seemingly leaves no reason for his heinous crimes.
