Carmen Colon, Wanda Walkowicz and Michelle Maenza

Over an 18 month period between 1971 and 1973 three girls aged 10 and 11 years old were abducted and murdered in the City of Rochester upstate New York, USA. Their names were Carmen Colon, Wanda Walkowicz and Michelle Maenza. They all had first and second names that began with the same initial, and each girl’s body was found in a town which began with the same initial as their name.
