Jack The Ripper Is An Alias Given To An Unidentified Serial Killer Active In The Largely Impoverished Whitechapel Area And Adjacent Districts Of London, England, In Late 1888. The Name Originated In A Letter Sent To The London Central News Agency By Someone Claiming To Be The Murderer. The Victims Were Women Earning Income As Prostitutes. Two Of The Victims' Throats Were Cut, After Which The Bodies Were Mutilated. Theories Suggest That The Victims First Were Strangled, In Order To Silence Them, Which May Explain The Reported Lack Of Blood At The Crime Scenes. The Removal Of Internal Organs From Three Of The Victims Led Some Officials At The Time Of The Murders To Propose That The Killer Possessed Anatomical Or Surgical Knowledge. Because The Killer's Identity Has Never Been Confirmed, The Legends Surrounding The Murders Have Become A Combination Of Genuine Historical Research, Folklore, And Seudohistory.
