She arrived in southeastern Ukraine in the summer of 2020 with a plan: dig a tunnel toward her son’s prison and help him escape. The scheme sounded absurd, if not impossible.

Then investigators found the hole.

The woman, whose name has never been revealed, was 51 years old at the time. She had traveled from Ukraine’s Mykolaiv region to the settlement of Kamyanske in Zaporizhzhia Oblast, rented a home nearby, and waited until it was dark to ride a quiet electric scooter toward the dig site, according to Ukrainian television reporting.

Her target was a prison complex near Kamyanske, where her son was reportedly serving a life sentence. For three weeks, she worked underground and dug a passage roughly 33 feet long and 10 feet deep toward the prison’s perimeter.

The tunnel never reached him. It’s unclear if it even reached the fence. But it got far enough to turn a local crime story into an international tale of design, devotion, and desperation.

The woman’s attempt was less like a prison-break plot than a dangerous feat of DIY engineering.

While the public details are still relatively scarce, the strongest account comes from TSN, which reported the woman had dug by hand, hid the dirt in an abandoned garage, and lay on a small plywood cart to move through the narrow tunnel. None of the reporting confirms that the woman dug directly into her son’s cell, but rather, toward a prison wall or perimeter. Even if she succeeded, the harder job would have come next: Just how would she have gotten past the fence and walls, found her son, and coordinated his escape anyway?

Still, the engineering is astonishing. Think about what it means to dig a tunnel that’s 33 feet long and 10 feet deep. That’s night after night of digging up reportedly tons of dirt, hauling it out of the shaft and into an abandoned building, and hiding in the tunnel without much room—literally—for error.

The next question is where, exactly, the tunnel was going. TSN said the prison was in the settlement of Kamyanske/Kamiane and held “lifers” and “murderers,” per an English translation, while a Pop Mech analysis of official records later suggested the Vilnyanska Institution for the Execution of Sentences No. 11, in Kamiane, as the likeliest site.

That October 2024 Ukrainian Ombudsman/National Preventive Mechanism report said that Vilnyanska held 167 people on the inspection date, including 104 people sentenced to life imprisonment.

The prison likely wasn’t a state-of-the-art facility. The same report describes Vilnyanska as having buildings that were only partially usable or in the middle of repairs, and another with a roof that had been 95 percent damaged in 2023. Vilnyanska officials even told the inspectors that for one building on the grounds, construction had dragged on for 20 years.

What’s even less certain, six years later, is what happened to the woman and her son after the escape attempt.

At the time, Ukrainian reporting indicated that the woman had been caught and criminal proceedings had been opened, with TSN speculating that “the mother will never meet her son, because she will serve her sentence in a women’s prison,” via English translation. But Pop Mech was unable to find any public report or statement that confirmed whether she was ever convicted, imprisoned, acquitted, or otherwise had the case resolved.

It’s also unclear if the woman’s attempt had any effect on her son’s status, though the legal world around his reported life sentence has changed since the incident. In 2021, Ukraine’s Constitutional Court ruled ruled that people serving life sentences couldn’t be automatically shut out from the possibility of parole or a reduced sentence. (This doesn’t mean the son was released, or even that he qualified for review.)

The Court’s separate 2023 ruling held that life-sentenced prisoners could not be categorically barred from short-term trips outside the colony for exceptional family circumstances, such as a family member’s life-threatening illness or death.

For all that has changed around the case, the mystery hasn’t: What became of the mom who dug a tunnel to free her son? And did it change anything for him? In the end, a daring, but unfinished rescue stayed that way.
