The Ontario Provincial Police (OPP) have charged a 51-year-old man from Quebec with first-degree murder, stemming from a case involving the discovery of a body in the Ottawa River last year. Luc Decarie, a resident of St-Gabriel-de-Brandon, was arrested on Thursday and faces serious charges, including indignity to a body and conspiracy to commit murder. He is set to appear in court today.

Discovery of the Body

The investigation began on May 17, 2025, when OPP officers from the Russell County detachment responded to a report of a deceased individual found in the Ottawa River, near Dallaire Street. The body was subsequently identified as Robert Prevost, a 63-year-old man from Clarence-Rockland, who had been reported missing in early March 2025. Prevost was last seen at his home on Laurier Street in early February.

An autopsy confirmed that his death was classified as homicide, prompting an extensive investigation by the police. The authorities have worked diligently over the past months to unravel the circumstances surrounding Prevost’s untimely death.

Details of the Charges

Decarie has been charged with not only first-degree murder but also with indignity to a body and conspiracy to commit murder. These serious allegations paint a grim picture of the events leading to Prevost’s death. The police have not disclosed further details regarding the nature of the conspiracy or the specific circumstances surrounding the murder, as the investigation is ongoing.

The OPP’s efforts in this case underscore the complexities involved in homicide investigations, particularly those that encompass multiple jurisdictions, given Decarie’s residence in Quebec.

Upcoming Court Appearance

The accused, Decarie, is scheduled to appear in court on Friday, where he will begin to face the charges laid against him. His legal proceedings will be closely monitored, especially given the serious nature of the accusations. This case has not only captured the attention of law enforcement but also the broader community, which is keen to see justice served.

Why it Matters

This case serves as a stark reminder of the ongoing issues surrounding violent crime and missing persons in Canada. The tragic death of Robert Prevost highlights the profound impact such events have on families and communities alike. As investigations like these unfold, they shed light on the importance of police diligence and community awareness in preventing and addressing crime. The outcome of Decarie’s trial could have significant implications for both the victim’s family and the wider public, as it raises critical questions about safety and justice in our society.
