An Ottawa woman facing a murder charge is the sixth person wanted in connection with the killing of a Clarence-Rockland man.
Ontario Provincial Police have an arrest warrant for Cathy Percey, 53, who is charged with first-degree murder in connection to the death of Robert Prevost.
Officials say Percey is known to frequent the nation’s capital, Rockland and Gatineau areas. They are asking anyone who sees the accused to call 911 and not approach her.
She is the sixth person police have laid charges against in the 2025 case.
The five others are:
Jessica St. Michael: First-degree murder and indignity to a body
Luc Décarie: First-degree murder and indignity to a body
Mathew Blake: Second-degree murder, indignity to a dead body and obstruct peace officer
Sebastien Boucher: Obstruct peace officer, obstruct justice and accessory after the fact
Yvon Vieno: Obstruct peace officer, obstruct justice, accessory after the fact and conspiracy to commit murder
The body of Prevost, 63, was pulled from a portion of the Ottawa River in the Dallaire Street area near Clarence-Rockland in 2025. He was reported missing for several months before his body washed ashore.
