For nearly half a century, the Lady in the Dunes was the ghost of Provincetown. She wasn't a legend or a folk tale, but a very real, very dead woman found in the Race Point Dunes on July 26, 1974. A young girl out for a walk with her dog stumbled upon a sight that would haunt Cape Cod for decades. It was gruesome. Her hands were gone—sawn off so she couldn't be fingerprinted. Her head was nearly severed. Her teeth? Removed. The killer didn't just want her dead; they wanted her erased.
Identity is a funny thing because we take it for granted until it’s stripped away. For years, investigators looked at this woman and saw a cipher. She was roughly 20 to 40 years old. She had auburn hair. She was lying on a beach blanket, her head resting on a pair of folded Wrangler jeans. But without a name, she was just a "Jane Doe," a cold case that felt like it was frozen in the salty Atlantic air.
The Breakthrough: Ruth Marie Terry Returns
In late 2022, the FBI and local authorities finally gave the Lady in the Dunes her name back: Ruth Marie Terry.
How'd they do it? Genetic genealogy. It’s the same tech that caught the Golden State Killer. Basically, they took degraded DNA from her remains and ran it against commercial databases like GEDmatch. They found distant cousins, built a family tree backward, and eventually landed on a woman from Tennessee who had vanished in the mid-70s. Honestly, it’s wild it took this long, but the technology just wasn't there in the '70s or even the early 2000s.
Ruth was 37 when she died. She was a mother. She was a daughter. She had a life before she became a headline. When the news broke, it wasn't just a win for forensic science; it was a gut punch for a family that had spent decades wondering why she stopped calling.
What Actually Happened in the Dunes?
The crime scene was bizarre. No signs of a struggle. The "Lady in the Dunes" was found face down. It looked almost like she was sunbathing, except for the violence. There was no weapon found at the scene. Because her hands were missing, police figured the killer was either a professional or someone who really, really knew how to cover their tracks.

The investigation went down some strange rabbit holes over the years. You've probably heard the rumors. One popular theory suggested she was an extra in the movie Jaws. Joe Hill, the author (and Stephen King’s son), noticed a woman in the background of the July 4th crowd scene in the film who looked remarkably like the sketches of the victim. She was wearing a blue bandana. The Lady in the Dunes was found with a blue bandana near her body. It was a compelling theory that gained massive traction online, but it never led to a concrete ID.
Then there was the Whitey Bulger connection. People thought the notorious Boston mobster might have been involved because he was known to frequent the area and had a penchant for removing the teeth and hands of his victims to hinder identification. It fit his M.O. perfectly. But like most theories in this case, it was a dead end.
The Husband: Guy Muldavin
Once Ruth Marie Terry was identified, the spotlight shifted immediately to her husband, Guy Muldavin.
They got married in early 1974. By the summer, she was dead. Muldavin was a "character," to put it lightly. He was an antiques dealer with a history that would make your skin crawl. He had been a suspect in the disappearance of another wife and a stepdaughter in Seattle back in the 1960s. When police found body parts in a septic tank at that Seattle home, Muldavin fled.
He was eventually caught but only charged with larceny related to his wife's bank accounts. He never faced murder charges for them. By the time Ruth was identified in 2022, Muldavin was already dead—he passed away in 2002. It's frustrating. It's a classic case of justice delayed being justice denied.

The FBI officially named him as the killer in 2023. They believe he killed Ruth shortly after they married, left her in the dunes, and simply moved on with his life. He was a chameleon. A con man. A monster hiding in plain sight.
Why It Took 48 Years to Find the Truth
The delay wasn't just about bad luck. It was a perfect storm of 1970s limitations.
- Jurisdiction Gaps: Ruth was from Tennessee, moved to Michigan, then California, and ended up in Massachusetts. In the 70s, police departments didn't talk to each other the way they do now. A missing person report in one state wouldn't automatically trigger a flag in another.
- The Mutilation: By removing her hands and teeth, Muldavin successfully bypassed the two most common ways people were identified back then.
- Social Isolation: Ruth had been somewhat estranged from certain family members, making it easier for her disappearance to go unnoticed or be explained away by a manipulative husband.
It's sort of haunting to think about how many "John and Jane Does" are just one DNA test away from going home. The Lady in the Dunes wasn't just a mystery; she was a person who was failed by the systems meant to protect her.
What This Means for Cold Cases Today
The resolution of the Lady in the Dunes case changed the game for cold case units across the country. It proved that no case is truly "unsolvable" if the biological material exists.
We're seeing a massive surge in "investigative genetic genealogy" (IGG). It’s basically using the tools we use to find our Irish ancestors to find murderers. While there are privacy concerns—kinda scary to think the government can find you because your second cousin took a 23andMe test—the results are hard to argue with.

If you’re following these kinds of cases, look at the work being done by organizations like Othram or the DNA Doe Project. They are the ones doing the heavy lifting now, taking cases that have been cold for half a century and bringing them into the light.
Actionable Steps for True Crime Enthusiasts
If you want to help solve cases like this, or if you're just fascinated by the process, here is what you can actually do:
Upload your DNA to GEDmatch. If you’ve done a consumer DNA test (Ancestry, 23andMe), you can download your raw data and upload it to GEDmatch. Make sure to "opt-in" to law enforcement searches. This is how they find the relatives of unidentified victims. Without a large enough database, the Lady in the Dunes would still be Jane Doe.
Support the DNA Doe Project. They are a non-profit that uses crowdsourced funds to pay for the expensive lab work required for these cases. Forensic DNA sequencing isn't cheap—it can cost thousands of dollars per body.
Check the NamUs Database. The National Missing and Unidentified Persons System (NamUs) is a public clearinghouse. You can browse through cases of unidentified remains and missing persons. Sometimes, a "regular person" makes a connection between a missing person report and a Doe just by looking at the details.
Pressure local representatives. Many states still don't have dedicated funding for cold case DNA testing. Writing to your local reps to support "Cold Case Task Forces" ensures that victims like Ruth Marie Terry don't stay nameless for another 50 years.
The mystery of the Lady in the Dunes ended with a name and a tragic story of a woman trapped by a violent man. While we can't give her justice in a courtroom, giving her back her name is a start. It’s a reminder that the truth is usually buried just beneath the surface, waiting for the right technology—and enough people who care—to dig it up.
