'Driven by Vengeance': How a Father's Violent Retaliation Shattered a Ukrainian Family seeking Refuge in Canada
When a Ukrainian family relocated to Saint John, New Brunswick, in 2023, their goal was survival - protecting their two young sons from the dangers of war and mandatory military service back home [1].
Instead, two years later, that haven turned into the scene of an unspeakable tragedy. On January 29, 2025, 46-year-old Roman Kamyshnyy brutally murdered his own sons - aged 10 and 17 - in their Millidgeville apartment in an act prosecutors described as calculated, cold-blooded revenge against his ex-wife [1].
Following a harrowing trial in the Court of King's Bench, a jury found Kamyshnyy guilty of two counts of first-degree murder [1]. Though publication bans protect the identity of the two young boys and their mother (referred to in court as Witness A), recently altered reporting restrictions have allowed the CBC to shed light on the full scope of domestic abuse, coercive control, and obsessive tracking that culminated in the killings [1].
Testifying from behind a screen to avoid eye contact with Kamyshnyy, the mother described her 20-year marriage as a "prison" [1]. While the family appeared happy on the surface, behind closed doors she lives in constant anxiety, enduring relentless emotional manipulation [1].
Hoping a fresh start in Canada would ease the strain, she agreed to the move [1]. However, proximity only heightened the tension. When she repeatedly asked for a divorce, Kamyshnyy dismissed her feelings, telling her she had a "hormone problem," was depressed, and would "never survive" without him [1].
After she legally filed for divorce remotely in Ukraine in late 2024, Kamyshnyy's behaviour escalated into systemic surveillance [1].
He secretly installed a GPS tracking device on the family vehicle to monitor her location while he worked long hours as a long-haul truck driver [1].
He hacked into her social media accounts, reading her private messages for months leading up to the murders [1].
Despite being legally divorced, financial pressures - including a $15,000 tax debt Kamyshnyy owed to the Canadian Revenue Agency - forced them to continue sharing the same apartment [1].
When she eventually decided to move on and went on a European vacation with a new partner, Kamyshnyy agreed to stay behind with the boys [1]. Court records reveal it was during this period that he began planning their deaths [1].
According to evidence presented during the trial, Kamyshnyy purchased a nail gun four days before the attacks and drafted a letter dated January 27 taking responsibility for his plan, explicitly blaming his ex-wife's alleged infidelity for his actions [1].
On the morning of January 29, 2025, while the 10-year-old was sleeping in bed, Kamyshnyy stabbed him multiple times with a kitchen knife [1]. The 17-year-old brother attempted to intervene and fled, managed to call 911, and hid in a closet, but Kamyshnyy broke the knife, grabbed a larger one, dragged his teenage son into the kitchen, and killed him [1].
At 7:08 a.m., immediately following the attack, Kamyshnyy sent a picture of his eldest son's body to his ex-wife with the message: "Go home. I killed everyone." [1] He then turned a nail gun on himself, shooting himself twice in the head in an attempted su***de [1].
In closing arguments, Crown prosecutor Elaina Campbell highlighted the motive behind the the tragedy [1]:
"Because for [her], what could be worse? A mother whose children are gone forever." [1]
Throughout the trial, Kamyshnyy claimed he had no memory of the killings, attributing his actions to alcohol consumption following the divorce [1]. However, digital evidence - including scheduled emails sent to the boys' mother calling her derogatory names, handwritten notes, and recorded police interviews - showed a deliberate plan to punish her for leaving the relationship [1].
Kamyshnyy faces an automatic life sentence with no possibility of parole for 25 years [1]. His formal sentencing is scheduled for August 13, 2026, where victim impact statements from family members and first responders will be presented with[1].
