The Bully With a Banner: How a Psychopath Used Social Justice to Destroy an Innocent Man
"I hate you. Really do. That's not against the law. I can hate you all I want."
Those words were spoken on camera, in broad daylight, by Katherine Hennessey — the woman who had spent the prior three weeks telling police, the courts, and the community of Shelburne Falls that John Sendelbach was a dangerous, racist, threatening presence who made her fear for her life. She said them without hesitation, without shame, and without apparent awareness that she was documenting her own motive for everything that had happened and everything that was coming.
She also said, in a letter to Sendelbach's landlord Brad Walker in September 2024: "It's only a matter of time before someone gets hurt."
Fourteen months later, someone did get hurt. On a public sidewalk outside Floodwater Brewing on November 30, 2025, John Sendelbach was shoved off a curb, beaten about the head and face while his arms were pinned, had his recording phone seized and thrown into the Deerfield River, and was then followed, tripped, and beaten again from behind. Cardiac monitors recorded his heart rate at 130 to 230 beats per minute. Emergency services attached a LIFEPAK 15 to his chest in the street.
The person whose letter had predicted that someone would get hurt was the person who ensured the prediction came true.
And then there is the comment from her daughter Alouette Batteau, posted publicly on Twitter in December 2022, in the middle of the family's five-year public positioning as anti-racism advocates: "i'm around far too many white people."
Three members of a family that destroyed John Sendelbach's life, career, health, and community standing while accusing him of racism. Three members of a family that used racial slurs against him on video, expressed racial contempt in public posts, and conducted what the record supports calling a racial hate crime — all while wrapped in the banner of social justice.
The irony does not land softly. It lands like a verdict.
The Target
John Sendelbach was not an unknown. He was the kind of man a town points to with pride — Cornell-educated, master's degree in landscape architecture, decades of work embedded in the physical landscape of western Massachusetts. Permanent installations on the Bridge of Flowers. Commissions from the Culinary Institute of America. Work at Deerfield Academy. The Brookie the Trout in Greenfield. The Sturgeon series. A gallery at 44 State Street that operated for nine years and drew repeat customers and commissions from institutions that don't give work to people who haven't earned it.
Carol Angus, co-chair of the Bridge of Flowers Committee, described him in print as a "great supporter of the bridge" who was "responsive to our needs." That was the community's settled understanding of John Sendelbach before Katherine Hennessey decided otherwise.
None of it survived her.
The Weapon She Chose
A psychopath does not choose accusations randomly. She chooses the accusation that produces maximum damage while offering minimum avenue for defense. In June 2020, at the peak of national reckoning following the death of George Floyd, "racist" was that accusation. It was unchallengeable by design — anyone who questioned it risked the same label. It was socially catastrophic in a community like Shelburne Falls, where reputation is everything and the distance between belonging and exile is a single public accusation.
She did not choose this weapon because Sendelbach was racist. He was not. The evidence is not merely the absence of racist behavior — it is the presence of its opposite, built into his work over decades. The Pothole Fountain he constructed in 2011 with stonemason Paul Forth contains Black Stones of Africa, placed there deliberately to honor Forth's mixed-race children as an act of artistic inclusion, nine years before the petition demanding his removal. The anti-racism plaque the Bridge of Flowers Committee installed "in response" to that petition was placed near a fountain already containing an explicitly anti-racist gesture they had apparently never noticed.
She chose the weapon because it worked. Not because it was true.
The Architecture of the Attack
On June 6, 2020, Sendelbach walked to the Iron Bridge to document an unannounced street closure that had shut down access to his business without warning. What followed was the founding act of the campaign — not because of what happened, but because of how it was packaged and distributed.
For more than two minutes he was physically surrounded against the east railing. Sonny Walters invaded his space and ignored three direct requests to leave. Katherine Hennessey got within six inches of his face, fists clenched, screaming. His exit was physically blocked. The police officer fifteen feet away watched without intervening. When Sendelbach finally responded — loudly, angrily, as any person would after two minutes of physical confinement — Alouette Batteau hit record on her phone.
The prior two minutes were not on that recording. The ignored leave requests were not on that recording. The encirclement, the blocked exits, the fists — gone. What reached twenty thousand viewers was a man yelling in a context that appeared to be a peaceful demonstration for racial justice.
The petition that followed was written by someone who had not been present at the event. It accused Sendelbach of racism, of disrupting a moment of silence for George Floyd, of stating "police lives matter most." It collected hundreds of signatures before being removed by Change.org for defamation and misinformation violations. By then the frame had set. Twenty thousand people had decided. The community had its story and the story had only one side.
This is how psychopathic narrative capture works. Not through argument. Through controlled emotional release, delivered at the moment of maximum cultural resonance, before the target has any opportunity to respond.
Five Years of Practiced Cruelty
What followed was not escalation in the ordinary sense. Escalation implies reaction — a response to resistance, a response to obstacle. What Katherine Hennessey conducted over the next five years had none of that reactive quality. It was consistent. It was methodical. It had the character of practiced execution rather than volatile emotion.
Eight police reports, 2020 through 2023. Not one survived contact with evidence. She claimed he had said "never let go as long as my family is alive." The audio captured his actual words: "I will never get along with the likes of you." She was laughing throughout the recording. She claimed he had accused community members of being KKK members. The audio from June 28, 2020 captured her applying that exact label to him, to his face, in a parking lot: "I don't talk to KKK members either, but here we are." She didn't merely lie. She inverted — took the documented evidence of her own behavior and reassigned it to her target in sworn affidavits, knowing the institution receiving the complaint would process it without verification.
The Shelburne Police Department obliged. Sergeant Gilmore put it in writing: "I've talked to John. It doesn't work." In one sentence he handed her unlimited access to the complaint system with zero accountability. For five years she filed reports and they were processed. In most of them, Sendelbach was never interviewed before charges were considered.
Three Harassment Prevention Order petitions. All denied or vacated. The first vacated when audio evidence directly contradicted the death threat she had described. The second denied along with coordinated simultaneous filings from her husband and daughter — a preemptive strike timed to make the conflict appear mutual before Sendelbach could file his own. The third — filed the morning after she assaulted him, while his phone was still on the bottom of the Deerfield River — denied with prejudice by Judge Mazanec. Denied with prejudice is a judicial finding that does not merely rule against a petitioner. It finds bad faith. It finds abuse of the legal process itself.
She filed it the morning after the assault. That is the move of a person who has used institutions as weapons for so long that the reflex is automatic — attack, then file for protection, before the other side can establish what actually happened.
In between these legal maneuvers were the landlord letters. The September 2024 letters to Brad Walker were not written in anger. They were composed — specific, targeted, designed to accomplish a specific outcome: Sendelbach's eviction from his studio at The Mill. The letters characterized him as dangerous, racist, sexist, transphobic, and threatening. Walker initially refused, noting there were no criminal or civil judgments against Sendelbach. After continued pressure, Walker joined the campaign. Sendelbach was constructively evicted in September 2025. His original gallery at 44 State Street had been lost following the 2020 campaign. The Mill was the second. When Hennessey appeared at the morning trespass on November 30, she had already located his third workspace. The pattern was systematic economic strangulation — not through direct action but through the weaponization of whoever held the keys.
And she put it in that letter to Walker: "It's only a matter of time before someone gets hurt."
She wrote that. She sent it. She was describing a future she was actively constructing.
November 30: The Fulfillment of a Promise
There is no legal framing, no clinical category, no documentary language that fully captures what happened on November 30, 2025. The records describe it accurately. The experience of it points to something the records can only approach.
That morning, Katherine Hennessey drove onto Sendelbach's rental property. Not past it. Onto it, directly to where his car was parked. She gave him the middle finger. Twice. Slowly. Then drove away. She had been at his new workspace twice in the prior weeks. She had worn a disguise to locate him at a public event on November 22. She had found him. She knew where he was. The morning visit was not impulsive. It was reconnaissance. It was announcement.
That evening, Brook Batteau came out of Floodwater Brewing first and shoved Sendelbach hard with both hands, sending him off the curb to the pavement. Katherine followed approximately ten seconds later.
What she did was not a fight. Fights are bilateral. What she executed was a sustained physical assault on a man who did not raise his hands in return — not once, not at any point in the attack. She struck him repeatedly in the head and face while a second person pinned his arms from behind. She bent down and seized his actively recording phone from the ground. She walked — not ran, walked — approximately seventy-five feet to the bank of the Deerfield River and threw it in. The screen was still lit as it arced through the air and landed thirty feet from the bank.
Then she came back.
That return is the detail that defines the evening. The phone was gone. The recording was gone. He was on the ground. Any ordinary person — even an enraged person, even someone acting from genuine fear — stops at that point. The confrontation is over.
She came back and followed him and tripped him and struck him in the head again.
This is what sustained, practiced, ideated violence looks like when it finally arrives. Not explosive. Not chaotic. Purposeful. The unhurried walk to the river. The deliberate return. The continuation of the attack after its stated purpose had been accomplished. This was not the first time she had imagined doing this. The premeditation is documented in the record that preceded it — in Alouette's 2020 post about wanting to deck him, which Katherine engaged with and endorsed. In the letter to Walker predicting someone would get hurt. In five years of escalating legal and physical harassment leading to this specific evening on this specific sidewalk.
The feeling Sendelbach describes — vile hatred, sinister repetition, something evil and unmistakable — is not a subjective impression. It is an accurate reading of what was actually there. He was not experiencing the aftermath of a confrontation that had gone too far. He was experiencing the fulfillment of something that had been planned and anticipated and moved toward for five years.
His cardiac monitors recorded between 130 and 230 beats per minute. Emergency services attached a LIFEPAK 15 to his chest in the street. Atrial fibrillation, per the American Heart Association, reduces life expectancy by five to ten years in untreated cases. His had been triggered by the stress of this campaign in 2020 and compounded by every confrontation since. She knew about the cardiac condition. It is in the public record of the proceedings she had filed. She knew, and she came back anyway.
The Family
Katherine Hennessey did not operate alone. She operated as the architect of a family unit in which her reality had become the household's reality and her enemies had become the family's enemies.
Brook Batteau spent five years receiving a story about John Sendelbach from the woman he lived with — a story confirmed by institutional responses that never challenged it, a story that accumulated five years of weight until he put that weight into a shove on a November sidewalk. His admission to neutral witness Zachary Livingston afterward — "You don't understand, John has been after my family for five years" — was the statement of a man who believed exactly what he said. That belief was not his own conclusion. It was installed in him, daily, by a woman who managed his perception of reality as deliberately as she managed every other instrument in her campaign. He is not a mastermind. He is a man who was fed a story for five years and finally acted on it. That changes nothing about his culpability. It illuminates everything about the woman who built the story.
Alouette grew up inside that story. She watched her mother execute the playbook from childhood and she learned it. She brought her own skills — the media architecture, the editorial precision of the edited video, the coordinated legal filings. By November 30, 2025, she had been in this school for a decade. Like mother, like daughter — not because Alouette arrived at cruelty independently but because living inside a psychopath's framework long enough reshapes what feels normal, what feels justified, what feels like self-defense rather than aggression.
The mother built the operation. The daughter learned it. The father was weaponized by it. And the man on the receiving end of all three lost thirty-five years of career, two businesses, his health, and his community while the people who did it to him called themselves the victims.
A Racial Hate Crime Wearing a Social Justice Costume
The family that conducted this campaign did not merely fail to embody the anti-racism values they publicly claimed. They produced, on the record, their own documented history of racial animus toward the man they were simultaneously accusing of racism.
Brook Batteau, on video, June 29, 2020: "Quit your white whining." A racial slur. Directed at Sendelbach. Captured on the recording that documented the family's hatred declaration.
Alouette Batteau, publicly, December 2022: "i'm around far too many white people." Posted during the years her family was positioning itself as the moral conscience of the community on racial matters.
Joey Kotright, at the June 6 demonstration, on camera: "cracker." A racial slur. Directed at Sendelbach. In the possession of a named witness.
Katherine Hennessey, in the June 28, 2020 parking lot, on audio: "I don't talk to KKK members either, but here we are." Applying that label to him. Which she then inverted in sworn affidavits and attributed to him, for five years, across every legal proceeding.
A man was labeled a racist, had his career destroyed, was driven from two studios, was beaten on a public sidewalk, and had his health permanently damaged. The people who labeled him were calling him racial slurs on video and expressing racial contempt in public posts throughout the entire campaign. The accusation was not a mistake. It was a weapon. And the people wielding it were not themselves free of the bias they attributed to their target.
This is what a racial hate crime looks like when it wears a social justice costume. The costume worked so well that the institutions, the press, and the community never looked underneath it.
What Was Destroyed and What Was Left
John Sendelbach writes, in his departure letter from The Mill after six years: "In six years here, not one person offered support or questioned the false narrative."
That sentence is the document's center of gravity. Not the assault. Not the false reports. Not the perjury documented across five years of proceedings. The silence. The silence of the people who knew him, had worked with him, had commissioned him, had attended his gallery — who had every reason to say something and said nothing.
His gallery is gone. His studio is gone. His health carries the documented cost of five years of sustained attack — a cardiac condition triggered in 2020 that has compounded with every confrontation since. His reputation in the community he built his career in was systematically dismantled by a woman who chose her weapon carefully, deployed it at the moment of maximum amplification, and relied on a system too siloed and a community too comfortable to ever put the full picture together.
The woman who predicted someone would get hurt made sure that prediction came true. The woman who said "I hate you and that's not against the law" proved, on November 30, 2025, that she was willing to go significantly further than hatred. And the woman whose daughter publicly lamented being around too many white people — three of whom, a mother and a father and a daughter, walked into John Sendelbach's life and took a wrecking ball to everything he had built — has, as of this writing, faced no consequence proportionate to what she did.
John Sendelbach did not choose these people. He did not invite the conflict. He walked to a bridge to document a street closure and found himself surrounded. Everything that followed was visited upon him by a family that hated him before they had a cause to justify it, selected a cause that would make the hatred unchallengeable, and then spent five years executing a campaign that the record, in every instance where evidence was actually examined, shows to be false from beginning to end.
The question the record leaves open — the question that Sendelbach himself is left to sit with — is not whether Katherine Hennessey is capable of everything she has already done. She has answered that question. The question is where she stops. A person who has ideated and executed every element of this campaign short of homicide, who wrote in a letter that it was "only a matter of time before someone gets hurt," who came back after the assault to keep hitting — a person like that does not stop because the legal system found probable cause. She files the next complaint. She identifies the next forum. She locates the next workspace.
The record does not offer reassurance on this point. The record offers only documentation.
And documentation, it turns out, is the one thing she cannot throw in the river.
John Sendelbach is a sculptor and horticulturist whose work appears on the Bridge of Flowers in Shelburne Falls, Massachusetts, at the Culinary Institute of America, and in public installations throughout western Massachusetts. All documented facts in this essay are drawn from police reports, court records, sworn statements, audio recordings, video evidence, and civil complaint filings.
