For 61 years, her killer had no name.\u00a0<\/p>\n
The only DNA investigators had to help identify 12-year-old Mary Theresa Simpson\u2019s killer was a speck so small that it was invisible to the naked eye. Recovered from her skirt after her murder in 1964 and carefully saved all these years, this was their last shot.<\/p>\n
FBI Special Agent Kenneth Jensen, who was assisting the Elmira Police Department in New York, knew what was at stake. If this sample failed, the case would likely die with it.<\/p>\n
He packed the fragile evidence in dry ice in a cooler and sent it to a lab in Texas known for doing the impossible with damaged DNA.<\/p>\n
Then everything froze.<\/p>\n
An ice storm had shut down the FedEx hub in Memphis\u00a0\u2013 the largest in the world \u2013 where the package was routed. The shipment sat stranded. If the dry ice gave out, decades of waiting would end in irreversible loss.<\/p>\n
The clock was ticking.<\/p>\n
\u201cWe couldn\u2019t even get ahold of anyone at FedEx during the historic storm,\u201d said Jensen, who now works as a forensic case manager at the National Center for Missing & Exploited Children (NCMEC). \u201cI was petrified that my act of shipping it through FedEx was going to lose the only chance of solving it.\u201d<\/p>\n
Jensen reached out to his fellow agents in Memphis. Remarkably, the bureau had a liaison to the FedEx hub, and the agent searched for the stranded DNA.<\/p>\n
\u201cIt was a massive scavenger hunt to find it,\u201d said Elmira Sgt. Bill Goodwin, the lead investigator.\u00a0 \u201cIt was nerve wracking enough getting our last piece of DNA tested. But now we\u2019re gonna lose it before it even gets to the lab.\u201d<\/p>\n
The FBI agent found it \u2013 just in the nick of time. He put the DNA in the bureau\u2019s freezer until the ice storm ended, then shipped it off to the lab in Texas.<\/p>\n
Now, the science could begin.<\/p>\n
Read the full story below of how law enforcement finally identified Mary Theresa Simpson\u2019s killer after six decades.<\/p>\n

Linda Galpin is 78 years old now and still thinks about her little sister every single day. Growing up in the \u201860s, they\u2019d play \u201ckick the can\u201d with other kids in their neighborhood in Elmira, New York and skate up and down the street on metal wheels that clamped to the soles of their shoes, tightened with a key.<\/p>\n
Galpin was 16 when her sister, Mary Theresa Simpson, 12, was murdered, a crime that rocked their small community to the core. Out of town when it happened, Galpin rushed home and was overcome at the sight of her shy little sister lying there so still.<\/p>\n
\u201cI couldn\u2019t believe she was in a casket,\u201d Galpin recalled in an interview with the National Center for Missing & Exploited Children (NCMEC). \u201cI tried to jump in it. I wanted to be in there with her.\u201d<\/p>\n
Today, more than 61 years later, Elmira Police Chief Kristen Thorne made a stunning announcement: They\u2019ve finally found Mary\u2019s killer. It\u2019s the oldest case ever solved with DNA.<\/p>\n
Over the years, dozens of law enforcement officers never stopped trying to figure out who killed \u201cMary Theresa,\u201d as they fondly called her. As time marched on, advancements in DNA and genealogy testing finally brought them answers.<\/p>\n
\u201cThis is a historic day for the Elmira Police Department,\u201d Thorne said at a press conference. \u201cJustice after 61 years.\u201d<\/p>\n
Perhaps most remarkable of all, police preserved evidence in the case for more than six decades, long before anyone even imagined DNA would become a powerful investigative tool.\u00a0<\/p>\n

Mary Theresa was last seen walking home from visiting relatives around 6:30 p.m. on March 15, 1964. Four days later, her body was found in a wooded area, seven miles from her home. Her body was partially hidden under four heavy stones, her mouth stuffed with dirt and twigs.\u00a0She died from asphyxiation.<\/p>\n
In 2003 \u2013 39 years after her murder \u2013 DNA found from semen on her skirt was entered into a national DNA database, but there were no matches. It was re-submitted again in 2014. Still nothing.<\/p>\n
Elmira police Sgt. William Goodwin was awarded a grant in 2022 for advanced DNA testing. Kenneth Jensen, an FBI special agent assisting with the case, shipped the DNA sample \u2013 0.4 nanograms, too small to see \u2013 to Othram Technologies for forensic DNA analysis.<\/p>\n
The lab uploaded a profile into two public DNA databases, and the FBI used it to build family trees, identifying a son who submitted a DNA sample.\u00a0<\/p>\n

His father, Raymond Murray, a truck driver, lived and raised a family in Elmira. Old news reports show he was arrested in cases involving children, including on charges of molesting two 7-year-old sisters when he was 17. He died when he was 72 of natural causes and was buried in Elmira. The end of the road? Not a chance.<\/p>\n
By this time, Jensen was retired and working for NCMEC as a forensic case manager. He told Goodwin, \u201cI think NCMEC can help.\u201d NCMEC provided the funds and expertise of a forensic anthropologist to exhume Murray\u2019s remains three months ago.<\/p>\n

Dozens of officers, many now retired, were there for the emotional moment. DNA confirmed that Murray had killed Mary Theresa. He was 33 when he killed her. The case has finally been closed. To her sister, the news was bittersweet.<\/p>\n
\u201cI\u2019m just glad justice was finally done,\u201d Galpin said. \u201cI always said it would never happen in my lifetime.\u201d<\/p>\n
