There is a particular kind of cruelty in what happened to Fawn Marie Mountain before she disappeared, one that played out slowly, methodically, and almost entirely out of public view. By the time she vanished in November 2012, she had been so thoroughly isolated from everyone who loved her that her family did not realize she was gone for almost three years. The woman who engineered that isolation, her partner Heather Dibert, was the last person to see her alive. No one has ever been charged in connection with Fawn's disappearance. Her body has never been found.

In September 2025, Heather Dibert was convicted by a jury on most of the charges against her in an unrelated murder-for-hire plot targeting a different woman. For Fawn's family, watching that verdict come down meant something. They have been sitting in courtrooms wearing purple shirts with her name on them, hoping that someone, somewhere, will finally tell them what happened to their daughter, their sister, their cousin. They are still waiting.

Who Fawn Was

Fawn Marie Mountain was born on March 2, 1987, in Blair County, Pennsylvania. Her early years were hard. She grew up navigating a childhood marked by abuse and instability, and as a young adult she fell into a series of toxic relationships that further destabilized her. She had three children, losing custody of two of them and losing the third, a daughter named Kaydin, to a stillbirth that devastated her deeply. She carried an urn with Kaydin's ashes almost everywhere she went. She had a tattoo across her back reading "RIP Kaydin," and another of her son Braydin's name on her neck. The urn and the tattoos tell you something essential about who Fawn was: a young woman carrying enormous grief, desperate for connection, reaching for something that kept slipping away.

Despite her struggles, the people who knew Fawn before Heather Dibert entered her life describe someone who stayed connected, who fought with her mother but always came back, who could not go long without reaching out to the people she loved. Her cousin Bridgette Gill, who would later become the engine behind the search for Fawn, has described her as someone with a big heart who never deserved what happened to her. Her mother Dorothy has said she could still hear Fawn's voice in her head, that her gut told her Fawn was no longer alive, even as she held onto whatever fragment of hope remained.

In 2009, Fawn met Heather Dibert. She was twenty-two years old, still searching, and she fell hard.

Heather Dibert and the Coercive Control

What started as a relationship quickly became something else. According to accounts from Fawn's family and documented evidence including police reports, Dibert's possessiveness escalated rapidly into a pattern of coercive control that would eventually swallow Fawn's entire world. Dibert did not like Fawn going anywhere without her. She forbade Fawn from working. She forbade her from having a phone. She restricted her movement so severely that Fawn was sometimes locked in cars and trailers. She separated Fawn from her family piece by piece, systematically cutting the threads that connected her to anyone outside the relationship.

The abuse was physical as well as psychological. Fawn went to the hospital on multiple occasions for injuries sustained at Dibert's hands. On at least one occasion, Dibert attempted to strangle her. Strangulation in domestic violence cases is widely recognized as one of the most significant predictors of future lethal violence. It is not simply assault; it is a demonstration of total control over another person's life.

Dibert had a history of this kind of behavior reaching back well before Fawn. Prior partners had taken out restraining orders against her. A police complaint from March 2012, just eight months before Fawn disappeared, documented an incident at the trailer park in Claysburg where Dibert and Fawn lived together. When officers arrived, they spoke with Fawn, who told them Dibert had been "abusive" in their relationship and that she "just wants to leave," but said that Heather would not let her go. Dibert pleaded guilty to disorderly conduct in that case. Nothing more came of it.

Dibert also began the process of alienating Fawn from her family through manipulation of the legal system. In 2011, Fawn abruptly filed a restraining order against her own mother, something her family believes was entirely Dibert's doing. The effect was devastating and practical: it meant that when Fawn showed up at her mother's house in October 2012, fleeing after a fight with Dibert, Fawn's mother was the one who got in trouble. Dibert found out Fawn had gone there, called the police, and Fawn's mother spent a weekend in jail for violating the protective order. That was the last time Fawn's mother ever saw her daughter.

The Night She Disappeared

On November 25, 2012, Fawn and Heather returned home to their trailer on Binks Mill Court in Claysburg after spending several days helping Dibert's parents clean and prepare their butcher shop. Dibert's brother and his girlfriend, who also lived in the trailer park, had come along to help and traveled back with them that evening. Dibert's brother's girlfriend was the last person other than Heather to see Fawn that night.

The following morning, that same girlfriend saw Heather outside, smoking a cigarette and talking with her parents. When she asked about Fawn, Heather said she had woken up at 3:00 a.m. to use the bathroom and noticed Fawn was gone. She had simply vanished in the night.

Fawn had left behind everything. The urn containing Kaydin's ashes, which she brought with her everywhere, was still in the trailer. Her clothes were still there. She had taken nothing with her. The woman who was forbidden from having a phone, who had no money of her own, who had been systematically cut off from every person in her life, had allegedly gotten up at three in the morning and walked away without a trace.

Heather Dibert, the woman who by every witness account could not stand to be separated from Fawn and tracked her compulsively, appeared remarkably unbothered. She did not call the police to report Fawn missing. She did not reach out to Fawn's family. Within a week of Fawn's disappearance, Dibert's family began remodeling the interior of the trailer, tearing up the flooring. Dibert then moved to Ohio. She returned to Pennsylvania several months later with a new girlfriend, whom she eventually married.

When Fawn's family tried to reach out over the following years, Dibert offered shifting and contradictory explanations for where Fawn had gone. She was in prison in Ohio. She was in New York, working in the sex trade. The stories changed depending on who was asking. None of them were ever verified.

Three Years of Not Knowing

Because of the restraining order Fawn had been made to file against her mother, and because Dibert had so thoroughly severed Fawn's ties to anyone who might have noticed her absence, no one formally reported Fawn missing for years. It was not until April 2015, when her stepfather lay dying in the hospital and her family desperately wanted Fawn to know, that they sent a family friend to the trailer park. Dibert told them Fawn had taken off three years earlier. It was at that moment, nearly three years after Fawn had last been seen alive, that her family filed a missing persons report.

The local police response was slow. Fawn's family felt for years that the case was not being taken seriously, that it was being treated as something other than what it almost certainly was. Pennsylvania State Police eventually took over the investigation. A trooper confirmed publicly that investigators had identified a person of interest in the case, but due to the active nature of the investigation, declined to name anyone. The family has never been told who that person of interest is. Officially, the case remains unsolved and open.

A Family That Refused to Be Quiet

The person most responsible for keeping Fawn's story alive is her cousin, Bridgette Gill. While law enforcement moved slowly, Bridgette did not. She organized candlelight vigils. She arranged for billboards bearing Fawn's photo and the word "missing" in bright red letters to go up along roads through Blair County. She set up a GoFundMe to raise money for a private investigator and to increase the reward for information. She built the Facebook page "Bring Fawn Marie Home," which grew from roughly 250 followers into tens of thousands after a pivotal moment in 2021.

That year, true crime YouTuber Kendall Rae covered Fawn's case in a video that accumulated over 1.6 million views and sent a surge of attention toward the case. Rae personally donated $12,000 to the GoFundMe, bringing it from $10,000 to $22,000, and the Facebook page's following exploded almost overnight. National and international attention turned, however briefly, to a young woman who had disappeared from a trailer park in central Pennsylvania a decade earlier with almost no coverage and almost no justice. Rae published an updated episode on the case in July 2023.

Fawn's mother, Dorothy, and her brother Allan have spoken to media repeatedly over the years. Dorothy has said that she can still hear Fawn's voice, that something in her gut tells her Fawn is no longer alive, but that she cannot let herself believe it fully until she has something concrete to hold onto. Allan has said simply that he misses her, that the whole family does, and that he just wants his sister to come home.

Heather Dibert's Conviction and What It Means for Fawn

In October 2023, Heather Dibert was arrested in connection with an incident that had nothing to do with Fawn but revealed everything about who she is. Dibert, by then estranged from the woman she had married after Fawn disappeared, allegedly hired a man named Zachery Sellers to burn down a home in Napier Township, Bedford County, where her estranged wife was staying with five family members. Dibert reportedly gave Sellers drugs and money in exchange for his agreement to carry out the attack. Sellers testified that Dibert drove him and his associate to the property, then left for a strip club in Virginia to establish an alibi. A Molotov cocktail was thrown at the house. Six people were inside, including children. No one died only because Sellers and his associate, confronted with the presence of children, did not fully execute the plan. Sellers told the court that when he called Dibert to say he was not going through with it because kids were inside, Dibert said: "She said they killed her baby so we had to kill their babies."

Dibert was arrested and charged with 32 felony charges including conspiracy to commit aggravated arson and solicitation of first-degree murder. Her bail was set at one million dollars. In May 2024 a judge denied her request to have it lowered. When her trial finally came, in September 2025, a Bedford County jury deliberated for just one hour before finding her guilty on most of the charges. Sentencing was scheduled for December 2025.

When news of Dibert's arrest in the murder-for-hire case broke in December 2023, members of Fawn's family and supporters traveled to the Bedford County courtroom wearing purple shirts emblazoned with Fawn's name. Dorothy Mountain, Fawn's mother, said she felt "ecstatic" when she heard about the arrest, not out of any celebration, but out of relief that someone else had been spared. She said she hoped Dibert would now tell investigators where Fawn was.

Investigators have not publicly announced any new developments in Fawn's case in connection with Dibert's conviction. No charges relating to Fawn have been filed. Her family has expressed hope that Dibert's conviction, and the pressure of incarceration, might finally loosen something, might finally lead to the one answer they have spent more than a decade waiting for.

Still Missing, Still Fighting

Fawn Marie Mountain would be 38 years old today. Her body has never been recovered. Her daughter's ashes, left behind in a trailer the night she vanished, are a detail that sits with you and does not let go. The woman who had carried that urn everywhere she went left it behind. She left everything behind.

Bridgette Gill has not stopped. The billboard campaign has continued. The GoFundMe remains active. The Facebook page is still running. A petition calling for the case to receive greater investigative attention has gathered thousands of signatures. The family's position has always been that the answer to what happened to Fawn is known, and that someone has to be made to say it out loud.
