The second ex-wife of David Brouillette, the ICE agent identified as the man who shot and killed Johan Sebastián Durán Guerrero in Biddeford on Monday, sent a message to reporters Saturday morning recounting what she described as Brouillette’s violent, abusive behavior, and that she had long anticipated his capacity to kill.
“If you were to ask me whether I believe David Brouillette is capable of this level of extreme violence, my answer is unequivocally yes,” Lucinda Brouillette wrote.
“That belief is not based on speculation, but on my own lived experiences over many years,” she said. “I have feared for a long time that his anger, aggression, and escalating behavior would eventually result in severe, life threatening violence, and I often believed I would be the one on the receiving end of it.”
Lucinda Brouillette sought a protection from abuse order in court this week and is asking a judge to temporarily award her sole custody of their 11-year-old daughter.
This is not the first time she has filed such an order against David Brouillette. Past court records show she has accused her ex-husband of kicking down her door and alleging that he routinely and falsely accused her of having substance-use issues to attack her credibility in court. She also claimed he sent videos of her in intimate settings to other people and was verbally and physically abusive to his daughters.
“Throughout the years, I brought my concerns to law enforcement, the courts, and the Department of Health and Human Services. I tried to explain what I believed was a long-standing pattern of abuse, intimidation, manipulation, and controlling behavior because I genuinely feared where those behaviors could lead,” Lucinda wrote.
Some of the protection requests between the pair were temporarily granted by a judge; all but one — which Lucinda filed in 2019, the year they got divorced — were ultimately dismissed within weeks of being filed.
On Thursday, a Kennebec County district judge declined to issue Lucinda Brouillette a temporary protection from abuse order after a hearing that David Brouillette attended, according to court records.
Lucinda Brouillette, who said that she was married to Brouillette throughout his military career, said her statement Saturday that she experienced consistent patterns of “abuse, intimidation, manipulation, fear, and control.” She said she fears retaliation from Brouillette, and is worried that he still could exercise violence against her.
David Brouillette, 37, served in the Maine National Guard from 2007 to 2010 and the U.S. Army from 2010 to 2015 as a human intelligence collector. He deployed to Afghanistan from May 2012 to February 2013, leaving the army as a sergeant. He has also held numerous law enforcement and public safety jobs in Maine.
“He frequently portrayed himself as someone who could manipulate people, deceive others, and stay in control of difficult situations,” Lucinda Brouillette wrote. “Whether those statements reflected reality or were intended to intimidate me, they contributed to an environment of fear that made it even harder for me to believe I could safely stand up to him.”
She said that it has been validating to see accounts of Brouillette’s disturbing behavior from others. Brouillette’s family members have reported similar experiences, and Ashley Brouillette, his first ex-wife whom he divorced in 2010, identified him to the Portland Press Herald/Maine Sunday Telegram on Thursday, alleging similar accusations.
“If there is one thing I hope comes from sharing my experience, it is that patterns of abuse, coercive control, intimidation, and manipulation are recognized and taken seriously before they escalate,” Lucinda Brouillette wrote.
In her statement, she asked that she and her family not be threatened or harassed because of her ex-husband’s actions.
“I hope the investigation uncovers the truth, justice is served through the legal process, and healing can begin for everyone affected,” she wrote.

Good morning,
My name is Lucinda, This is my response to your questions regarding my experience or knowledge of my ex husband, David Brouillette.
Before anything else, I want to express my deepest condolences to the victims, their loved ones, and every person whose life has been forever changed by this tragedy. My heart is with all of those who are grieving.
For several days, I have watched these events unfold alongside the rest of the country. I have intentionally been careful not to speculate about the incident itself. I was not there, I do not know exactly what happened, and I believe the facts should be determined by investigators and the justice system — not by public opinion.
What I can speak to is my own experience.
If you were to ask me whether I believe David Brouillette is capable of this level of extreme violence, my answer is unequivocally yes. That belief is not based on speculation, but on my own lived experiences over many years. Throughout our marriage and in the years that followed, I have feared for a long time that his anger, aggression, and escalating behavior would eventually result in severe, life threatening violence, and I often believed I would be the one on the receiving end of it.
I was married to David Brouillette throughout his entire military career. During those years, and for many years after our marriage ended, I experienced a persistent pattern of abuse, intimidation, manipulation, fear, and control. On multiple occasions David’s physical abuse was witnessed by friends and family. The emotional, psychological, and physical scars of those experiences have remained with me long after the marriage ended.
One of the most difficult aspects of that relationship was the fear of retaliation. Throughout our marriage and long afterward, I believed that whenever I spoke up, challenged him, or sought help, there would be consequences. That fear influenced countless decisions I made, including when and how I reported what I was experiencing. Even now, I fear speaking the truth of my experiences will lead to retaliation.
David often spoke to me about his military intelligence background and the specialized skills he believed it gave him. He frequently portrayed himself as someone who could manipulate people, deceive others, and stay in control of difficult situations. Whether those statements reflected reality or were intended to intimidate me, they contributed to an environment of fear that made it even harder for me to believe I could safely stand up to him.
Throughout the years, I brought my concerns to law enforcement, the courts, and the Department of Health and Human Services. I tried to explain what I believed was a long-standing pattern of abuse, intimidation, manipulation, and controlling behavior because I genuinely feared where those behaviors could lead. From my perspective, those warnings did not receive the attention I believed they deserved. Feeling unheard while continuing to fear retaliation was one of the most isolating experiences of my life.
The concerns I describe here are not new. They were raised over many years through family court proceedings, reports to law enforcement, and communications with the Department of Health and Human Services. Those proceedings span years and are matters of public record. My purpose in making this statement is not to relitigate those proceedings, but to explain my own experience and why I carried these concerns for so long.
For many years, I questioned whether anyone would believe what I had experienced. Seeing others with firsthand knowledge now come forward publicly has been deeply validating. While I cannot speak for anyone else’s experiences, hearing similar accounts has reinforced that I was not alone in what I experienced.
This statement is not about speculating on the events currently under investigation or influencing the outcome of any criminal case. It is about sharing my own lived experience and explaining why I carried these concerns for so many years.
If there is one thing I hope comes from sharing my experience, it is that patterns of abuse, coercive control, intimidation, and manipulation are recognized and taken seriously before they escalate. I know firsthand how difficult it is to speak up when you fear retaliation or believe no one will listen. If my experience encourages even one person to seek help, or encourages one person, one agency, or one court to take those warning signs more seriously, then sharing my story has served a purpose.
I also ask that people remember something very important. David Brouillette is the individual involved in the criminal case that is currently under investigation. I am not. Our children are not. My family is not. We did not choose this situation, and we should not be judged, threatened, harassed, or defined by someone else’s alleged actions.
My children deserve the opportunity to grow up without carrying the weight of circumstances they did not create. My family deserves privacy, compassion, and the chance to move forward without fear.
My thoughts remain with the victims, their loved ones, and every family whose lives have been forever changed by these events. I hope the investigation uncovers the truth, justice is served through the legal process, and healing can begin for everyone affected.
