The Ottawa Police Service has completed its probe into the deaths of two young boys and their father in Ottawa’s south end, releasing a timeline of events that led to what investigators are calling a suspected double murder‑suicide.

Investigation timeline and neighbourhood scene

Police were called to the residence on Mandevilla Crescent on June 29, 2026. Officers spent the following days conducting forensic and neighbourhood inquiries. The service has now concluded the investigative phase and provided the public with a chronology of the events it examined.

Date Event
June 29, 2026 Police presence at Mandevilla Crescent; response to the deaths
July 21, 2026 Ottawa Police Service announces conclusion of investigation

Scope and findings

The public update did not identify the victims by name. Police described their work as focused on establishing the sequence of events and determining the manner of death. Investigators concluded the deaths involved the two children and their father and treated the incident as a suspected double murder‑suicide.

  • Location: Mandevilla Crescent, Ottawa south end
  • Date of response: June 29, 2026
  • Outcome: Investigation concluded; incident described as a suspected double murder‑suicide

Community response and next steps

Neighbours and community members were left shaken by the incident and the heavy police presence at the scene in late June. Police said they completed the investigative steps required and have closed their active investigation. The service did not announce additional criminal charges in connection with the deaths.

Ottawa Police continue to provide support to affected family members through victim services and to respond to inquiries from the public as needed. Residents seeking help or information related to traumatic events in their community are encouraged to contact local supports and police victim‑assistance programs.

The closure of this investigation addresses outstanding questions about the police response and forensic work; it does not alter the impact on the neighbourhood or the grieving process for the family and community.
