A man from Saint John who was found guilty of two counts of first-degree murder for stabbing his 10 and 17-year-old sons in 2025 is set to receive his sentence today. Roman Kamyshnyy, aged 46, will appear at the Saint John Court of King’s Bench at 11 a.m. The jury reached a guilty verdict on June 24 after a brief deliberation period spanning two days.
The prosecution contended that the murders were motivated by revenge and intended to punish his ex-wife, the boys’ mother, over allegations of infidelity. The court learned that she had recently divorced him and was away in Ottawa for a work-related event at the time of the tragic incident.
Despite a publication ban protecting the identities of the woman, referred to as Witness A, and the victims identified as A.B. and C.D., CBC News can now disclose the relationships in this domestic violence case.
During Kamyshnyy’s trial, 23 Crown witnesses, including Witness A, testified for two weeks. As part of the sentencing process, Victim Impact Statements, including those from first responders, were allowed.
First-degree murder carries an automatic life sentence with no chance of parole for 25 years. However, a recent ruling by the Supreme Court of Canada declared that consecutive parole ineligibility periods are unconstitutional, mandating that they be served concurrently.
The crime scene was discovered by Saint John police on January 29, 2025, where both boys were found with multiple stab wounds inflicted by knives matching a set from the kitchen. Kamyshnyy was also found at the scene after attempting suicide by shooting himself twice with a nail gun.
The prosecution argued that Kamyshnyy meticulously planned the murders over eight days, first targeting the younger son while he slept and then attacking the older one in the kitchen. Kamyshnyy, in his defense, denied premeditation, claiming he had no recollection of the events of that day.
