Hamilton Howard "Albert" Fish (May 19, 1870 – January 16, 1936) was an American serial killer, child rapist and cannibal. He was also known as the Gray Man, the Werewolf of Wysteria, the Brooklyn Vampire, the Moon Maniac, and The Boogey Man. Fish once boasted that he "had children in every state", and at one time stated his number of victims was about 100. However, it is not known whether he was referring to rapes or cannibalization, nor is it known if the statement was truthful. Fish was a suspect in at least five murders during his lifetime. Fish confessed to three murders that police were able to trace to a known homicide, and he confessed to stabbing at least two other people. He was put on trial for the kidnapping and murder of Grace Budd, and was convicted and executed by electric chair. His crimes were dramatized in the 2007 film The Gray Man, starring Patrick Bauchau as Fish.

Corll and his accomplices buried 17 of their victims in a rented boat shed; four other victims were buried in woodland near Lake Sam Rayburn; one victim was buried on a beach in Jefferson County; and at least six victims were buried on a beach on the Bolivar Peninsula. Brooks and Henley confessed to assisting Corll in several abductions and murders; both were sentenced to life imprisonment at their subsequent trials.Corll was also known as the Candy Man and the Pied Piper, because he and his family had owned and operated a candy factory in Houston Heights, and he had been known to give free candy to local children.
