Update: Investigation into Death of Thunder Bay Woman

Case Number: 23-OOD-536   

Mississauga, ON (11 January, 2024) ---
The Special Investigations Unit continues to probe the death of a 21-year-old woman at a residence in Thunder Bay on Saturday, December 30, 2023. 

Witness interviews are ongoing and the initial results of the autopsy have been received.  The police communications recordings have been reviewed. 

The information that can be released by the SIU remains limited at this stage of the investigation. However, having reviewed the police communications recordings, the SIU can confirm at this time that the 911 call initially received by the Thunder Bay Police Service was not in relation to violence in the home involving the woman.  The caller had contacted police to report that the woman was an unwanted visitor at her home as there were court conditions that she and her son, also present in the home, were not supposed to be around each other.  The caller was concerned that her son could be arrested for breach of the conditions and she asked that the police remove the woman from the home.  The same caller subsequently contacted police to cancel the call for service, reporting that the woman had left the residence.

The SIU is urging anyone who may have information about this investigation, including video or photos, to contact the lead investigator at 1-800-787-8529 or online at:
