Summary: CityNews Ottawa reported on Jan. 30, 2026 that police charged 41‑year‑old Selina Rose O’Qui

Selina Rose O’Quinn, 41, was charged with second-degree murder in the fatal stabbing of 28-year-old Shawn Challis-Eatough, following an incident in Ottawa’s Carlington neighbourhood on Jan. 29. Police laid the charge on Jan. 30, and O’Quinn is the third person charged in the investigation into the death.

The stabbing left a young man dead and prompted an intensive police inquiry into what investigators describe as a multi-person incident. The involvement of multiple accused changes the investigative and prosecutorial landscape: detectives are likely reconstructing timelines, communication between suspects, and each person’s role in the events that led to the homicide. For true crime observers interested in modus operandi and group dynamics, the progression from initial arrests to a third charge is a key development that can signal complicity, conspiracy, or escalating violence.

In legal terms, a conviction for second-degree murder in Canada carries a mandatory life sentence. Parole ineligibility is determined by a judge and can range up to 25 years, making second-degree murder among the most serious charges a defendant can face. With O’Quinn now charged, the next steps include court appearances, disclosure of evidence, and potential additional charges as the investigation continues.

Community impact in Carlington is immediate. Neighbours report a heightened sense of concern anytime a violent death occurs in a residential area, and the presence of multiple accused tends to amplify those concerns. Practical implications for readers include remaining vigilant, reporting any information to police, and looking out for community safety updates from local authorities. For members of Shawn Challis-Eatough’s circle, the coming weeks will be critical as investigators gather witness statements and forensic evidence that could clarify motive and sequence of events.

Authorities have characterized the matter as an ongoing investigation. That means developments can unfold quickly, from new charges to court dates and evidence releases. True crime followers tracking this case should expect authorities to reveal additional details as charges are vetted and prosecutors prepare files.

What this means going forward is twofold: legally, the charge of second-degree murder places O’Quinn into a lengthy criminal process that may include further indictments; publicly, Carlington and the wider Ottawa community will watch for how police and courts handle a case involving multiple accused. Expect continued reporting on court proceedings and investigative milestones as the story develops.
