Jack the Ripper, who remains unidentified to this day, roamed London killing five women, some of them prostitutes. Of the hundreds of letters sent in his name to police and the press in Victorian London, the three sent in September and October 1888 to the Central News Agency are considered most likely to be real. The most famous is the "From hell" letter, which was accompanied by a piece of human kidney supposedly from one of the mutilated victims. On the paper's upper right corner, it read, "From hell." He wrote: "I shant quit ripping [whores] till I do get buckled [sic]. Grand work the last job was. I gave the lady no time to squeal. How can they catch me now. I love my work and want to start again." The writer claimed to have "fried up" and eaten the other half of the kidney—and to have saved some blood to use as ink. The only problem: It had dried up.
In a postcard sent to "dear old Boss" at the Central News Agency, the killer called himself "Saucy Jacky," and thanked the recipient for not publishing the letter earlier than asked. A few weeks later, a third letter went to George Lusk, president of the Whitechapel Vigilance Committee, which had been formed to patrol streets in the neighborhood where the murders had taken place. In another, the killer wrote, "Sorry about the blood still messy from the last one. What a pretty necklace I gave her." He was referring to his victim's throat.
1934: Albert Hamilton Fish
Fish, a.k.a. The Gray Man, The Moon Maniac and The Brooklyn Vampire, confessed to three murders and was convicted (and later executed) for one of them—the 1928 strangling of 10-year-old Grace Budd. In 1934, Grace's mother received a rambling and misspelled letter. The writer said he had become fascinated by tales of cannibalism and, on meeting Grace, had resolved to kill her: "I called on you…we had lunch. Grace sat in my lap and kissed me. I made up my mind to eat her." Police traced the letter back to Fish (who had used a fake name when meeting the Budds) through a stationery logo. Authorities believed he might have also been the so-called Brooklyn Vampire, a murderer/rapist of children. When the police asked why he wrote to his victim's family, he reportedly said, "I just had a mania for writing."
1946: The Lipstick Killer William Heirens
"For heavens sake catch me before I kill more I cannot control myself." Those were the words scrawled in lipstick on the wall of divorcée Frances Brown's Chicago home. She was found with a knife lodged in her neck and a bullet wound to the head. Later, six-year-old Suzanne Degnan disappeared from her home; the killer left behind a ransom note. The little girl's body was found chopped up in sewer pipes all over town. Heirens confessed to the two horrific murders (plus another) and spent the rest of his life in jail; he later recanted his confession.
