A 37-year-old Ottawa woman has become the second person charged with first-degree murder and indignity to a body in connection with the death of a Clarence-Rockland man in 2025.

The Ontario Provincial Police announced Friday, June 12, that Jessica St. Michael had been arrested a day earlier with the assistance of the Gatineau Police Service.

She remained in custody and was scheduled to appear before the Ontario Court of Justice in L’Orignal on Friday, a police news release said.

On June 4, 51-year-old Luc Décarie of St-Gabriel-de-Brandon, Que., was arrested and also charged with first degree murder and indignity to a body.

The investigation began May 17, 2025, when officers from the OPP’s Russell County detachment responded to a report of a body discovered in the Ottawa River near Dallaire Street in Clarence-Rockland.

Post mortem examination identified the victim as Robert Prévost, 63, of Clarence-Rockland, who was reported missing in March 2025. His death was ruled a homicide.

The OPP said the investigation was continuing.

Anyone with any information about the case was asked to contact the Russell County OPP at 1-888-310-1122. Anonymous tips can be delivered to Crime Stoppers toll-free at 1-800-222-8477 or online at ontariocrimestoppers.ca.
