The 1964 Elmira Murder: How DNA Finally Named Mary Simpson's Killer 61 Years Later

Cold case solved 61 years later: How forensic DNA genealogy named the killer of 12-year-old Mary Theresa Simpson — the oldest U.S. homicide ever cracked by DNA. In March 1964, Mary Theresa Simpson walked home through Elmira, New York and vanished. Detectives interviewed 300 people. No suspect was ever charged. The case file grew for six decades. The killer lived in the same city, raised a family, and died in 2004 without a single question ever being asked of him. This investigation examines how a 2022 grant application, a forensic laboratory in Texas, 0.4 nanograms of biological material surviving in a police department freezer, and a FedEx package stranded in a Memphis ice storm converged — after 61 years — to finally name Alfred Raymond Murray Jr.: Korean War veteran, Elmira grandfather, convicted by a dead man's exhumed DNA. What the Elmira Police detectives preserved in 1964 — without knowing what DNA was — became the evidence that broke the case in 2026. This is what forensic genetic genealogy actually looks like at the edge of its capability.
