Junior Officer Admits Guilt in Case with Disgraced Winnipeg Constable

A former Winnipeg police officer, Matthew Kadyniuk, has admitted guilt in a case involving theft and a breach of trust. This incident arose during a police integrity test that occurred in October 2024. Kadyniuk’s co-accused, Elston Bostock, is a fellow officer who has faced numerous convictions over several years.
Details of the Case
On a recent Friday, Kadyniuk, 34, entered his plea of guilty in the Winnipeg courtroom. He now faces consequences for theft under $5,000 and compromising his duty as an officer. His choice of words—just a quiet “guilty”—was noted by the court clerk.
Background of the Investigation
The integrity test was part of an extensive investigation initiated in April 2024. This probe was triggered by reports that Bostock was engaged in illicit activities with individuals outside the police force, sharing confidential police information with them. By September 2024, authorities obtained approval to record Kadyniuk and Bostock under a staged scenario.
On October 17, 2024, Kadyniuk and Bostock responded to what they believed was a vehicle break-in, which was orchestrated by an undercover RCMP officer. The operation allowed police to monitor and record the officers’ actions as they wrongly confiscated a backpack containing crime-scene items.
Actions Leading to Arrest
- During the staged incident, Kadyniuk and Bostock took cash and other items from the backpack.
- After realizing the integrity test was implemented, they were nervous about the validity of the call.
- Both officers used some of the stolen money for breakfast.
Kadyniuk, currently suspended without pay, has been informed that a review of his employment status is underway. His attorney suggests that prosecutors may seek a community-based sentence of up to two years, while Kadyniuk’s defense aims for a suspended sentence.
Additional Developments
While Kadyniuk faces immediate sentencing, his actions and those of Bostock have broader implications. Two other officers connected with this ongoing investigation are also facing charges, indicating systemic issues within the department.
Justice Kenneth Champagne stated the seriousness of Kadyniuk’s situation is clear. The court will reconvene for a subsequent hearing to finalize his sentence.
As the situation develops, the Winnipeg Police Service continues to assess the outcomes of these events and maintain public trust in law enforcement.
