When?

Several of the most notorious serial killers in the U.S. include H. H. Holmes or Herman Webster Mudgett, Charles Manson, Ted Bundy, Jeffery Dahmer, the Zodiac Killer, and the Green River Killer, Gary Ridgeway, though there are many many more. Holmes was the first documented killer in America; he confessed to the murders of 27 people from 1891 to 1895 and was imprisoned in Moyamensing Prison. He was killed on May 7, 1896. Charles Manson and four other people killed actress Sharon Tate in 1969. The Manson Family all together was officially charged with killing seven people. Ted Bundy killed over 30 people by 1989, the time of his execution. Jeffrey Dahmer killed, dismembered, and cannibalized 17 young men from the Milwaukee area. The Zodiac Killer was never identified, but he killed five people in Northern California from December 1968 to October 1969. He confessed to 37 murders in total, but because he was never found, the truth of his claims remains doubtful.
