At 4:20 p.m. on November 16, 1971 a 10-year-old Puerto Rican child named Carmen Colón disappeared while returning home from an errand in Rochester, New York. Seventeen months later, at approximately 5:00 p.m. on April 2, 1973, 11-year-old Wanda Walkowicz disappeared from the east side of Rochester while returning home from an errand. Seven months later, on the evening of November 26, 1973, 11-year-old Michelle Maenza was reported missing by her mother after she failed to return home from school. They had been raped before being strangled to death. Each girl had ingested food shortly before their death. This was significant since neither girl was known to have eaten prior to her disappearance.
