This serial murderer terrorized Rochester, New York, and the surrounding area from 1971 until 1973. He claimed the lives of three innocent little Rochester girls before he was finished, dumping heir bodies in nearby towns. Then he apparently vanished, never to surface again. Dubbed "The Alphabet Murders" because in each case the victims first and last name and the town they were discovered slain in began with the same letter.

The slayings began when 11-year-old Carmen Colon was found murdered in Chuchville in 1971. Wanda Walcowicz (reported as being either 10 or 11) was found slain in Webster in 1972. The final victim was Michelle Maenza, 10, discovered in Macedon in 1973. Each girl showed evidence of being raped before death. In addition to the alphabet angle and the obvious age similarity, all three victims were from poor Roman Catholic families in Rochester and were reportedly in trouble at school, sparking speculation that the three homicides could have been committed by some sort of counselor that had access to all three girls. After his arrest as one of Los Angeles' "Hillside Stranglers" Kenneth Bianchi became a suspect in the homicides of Colon, Walcowicz, and Maenza. Bianchi was born in Rochester and still lived there when the girls were murdered, but no evidence was ever found to connect him with the killings.
