Guess the Famous Murderer

XX graduated from the University of Washington in 1972, and was a psychology major. XX was described by classmates as a master manipulator. XX lured his female victims by faking injuries, then overpowering them. XX admitted to killing 36 women, however, it is speculated that the actual number of victims is higher. Who is the murderer?

From 1974 through 1991, the Wichita, Kansas area was gripped by a string of murders that were attributed to a fiend known as the XX. The crimes went unsolved until 2005. After his arrest, XX confessed to killing 10 people over the course of 30 years. He had notoriously toyed with authorities by leaving letters and sending packages to local news outlets. His last correspondence in 2004 led to his arrest.

XX terrorized the New York City area in the 1970s with a string of brutal, seemingly random homicides. XX wrote confession letters to police and media after his crimes.

This bizarre case involved a series of letters sent to three California newspapers. In many of the missives, an anonymous perpetrator confessed to the murders. Even more chilling, however, were the threats he made saying that if his letters were not published, he would go on a murderous rampage.

Beginning in 1977, in a killing spree that started in Washington State and extended all the way to Los Angeles, the heinous pair raped, tortured, and murdered a total of 10 girls and young women.

In the late 1960s, a charismatic drifter with delusions of rock and roll grandeur named XX coerced a number of young women and men, many of whom were vulnerable teenagers, to join a cult called "The Family."
