|The Alphabet Killer|
|Birth name||Unknown identity|
|Also known as||The Double Initial Killer|
|Number of victims||3|
|State(s)||Rochester, New York|
The so-called "Alphabet murders" (also known as the "double initial murders") took place in the early 1970s in the Rochester, New York, area; three young girls were raped and strangled. The case got its name from the fact that each of the girls' first and last names started with the same letter (Carmen Colon, Wanda Walkowicz, and Michelle Maenza) and that each body was found in a town that had a name starting with the same letter as each girl's name (Colon in Churchville, Walkowicz in Webster and Maenza in Macedon).
- Carmen Colon, 10, disappeared November 16, 1971. She was found two days later, 12 miles from where she was last seen. Although found in the town of Riga, the village of Churchville is the town's center of population, and the town of Chili is nearby.
- Wanda Walkowicz, 11, disappeared April 2, 1973. She was found the next day at a rest area off State Route 104 in Webster, seven miles from Rochester.
- Michelle Maenza, 11, disappeared November 26, 1973. She was found two days later in Macedon, 15 miles from Rochester.
While hundreds of people were questioned, the killer was never caught. One man, considered to be a "person of interest" in the case (he committed suicide six weeks after the last of the murders), was cleared in 2007 by DNA testing. In the case of Carmen Colon, her uncle was also considered a suspect until his suicide in 1991.
Another suspect was Kenneth Bianchi, who at the time was an ice cream vendor in Rochester, vending from sites close to the first two murder scenes. He was a Rochester native who later moved to Los Angeles, and with his cousin Angelo Buono, Jr. committed the Hillside Strangler murders between 1977 and 1978. Bianchi was never charged with the alphabet murders, and he has repeatedly tried to have investigators officially clear him from suspicion; however, there is circumstantial evidence that his car was seen at two of the murder scenes. He remains under suspicion.
On April 11, 2011, 77-year-old Joseph Naso, a New York native who lived in Rochester in the 1970s, was arrested in Reno, Nevada, for four murders in California dating back to 1977. His alleged victims were named Roxene Roggash, Pamela Parsons, Tracy Tofoya, and Carmen Colon (not the one listed in Rochester, but another person of the same name). All four women are described by authorities as prostitutes. Naso is being looked at as a "person of interest" in the Alphabet Murders in New York. Admitted into evidence in his preliminary hearing in Marin County, CA, on January 12, 2012, was his alleged "rape diary," which mentioned the death of a girl in the "Buffalo woods," a possible allusion to Upstate New York. Naso was a professional photographer who traveled between New York and California extensively for decades.
