As previously released:

On June 15, 2023, at approximately 1:50 a.m. Winnipeg Police Service General Patrol members responded to Abinojii Mikanah and Newmarket Boulevard regarding the sound of shots.

Further information led officers to a suite in the 400 block of Ballantrae Drive. Upon entry to the suite, two uncooperative males and a female were located and identified.

The investigation revealed that the occupants had attended to the suite balcony while armed with a rifle and discharged multiple rounds into a field behind the residence. As a result, members of the Winnipeg Police Service were summoned. No injuries were reported.    

Members of the Major Crimes Unit continued the investigation, executing search warrants. The following was located in the suite and seized by officers:

- Fully operational SKS – semi-automatic rife

- Two additional rifles/shotguns in various states of disassembly

- Ammunition

- 23 rocks of crack cocaine  - estimated street value $4,600

- various scales and packaging materials consistent with drug trafficking

Mason BUCHNER-MONKMAN, 24, Devon Nicholas James MEYER, 24, and a 23-year-old female of Winnipeg, have been charged with numerous weapon and drug-related offences.



In March 2024, the Winnipeg Police Service’s Major Crimes Unit continued its investigation regarding BUCHNER-MONKMAN and MEYER and linked them to two additional Winnipeg incidents in June 2023.

On June 14, 2023, the suspects were present in the area of Magnus Avenue and Main Street, one armed with a 12-gauge shotgun and ammunition. During the incident, one of the suspects produced and loaded the firearm before passing it to the other. This suspect proceeded to recklessly discharge the shotgun numerous times, striking an unoccupied vehicle parked in the 1000 block of Main Street. No persons were injured during this incident. Both suspects fled before police arrived.

On June 15, 2023, at approximately 12:40 a.m., the suspects attended a hotel establishment in the 300 block of St.Mary Avenue and announced to the front desk employees that they were being robbed. One of the suspects produced a canister of bear spray and discharged its contents at the 31-year-old and 61-year-old male victims. The victims suffered from the effects of the bear spray but were otherwise uninjured. Both suspects fled on foot before police arrived. No property was stolen during the incident.

Investigators obtained arrest warrants for both regarding their involvement in the abovementioned incidents.

In December 2023, investigators learned that BUCHNER-MONKMAN fled to Nelson, British Colombia, violating the conditions of his release order. Investigators consulted with Manitoba Prosecutions, who issued an extension for one of BUCHNER-MONKMAN’s arrest warrants to a Canada-wide radius. Investigators summoned the assistance of the Nelson Police Department to locate and arrest BUCHNER-MONKMAN.

On March 27, 2024, a coordinated effort involving the Nelson Police Department (NPD) and British Columbia Prosecution Service resulted in the arrest of BUCHNER-MONKMAN by NPD officers on the strength of the Canada-wide warrant at a residence in Nelson. He was conveyed to Kelowna, turned over to the custody of WPS Major Crimes Unit investigators, and flown back to Winnipeg.

In addition to eight (8) arrest warrants in his name, BUCHNER-MONKMAN is charged with multiple weapon and firearm-related offences, robbery, and failure to comply with release order conditions. 

Investigators had previously attended the Milner Ridge Correctional Facility on February 17, 2024, where MEYER was being held regarding unrelated incidents and placed him under arrest. He was charged with multiple weapon and firearm-related offences and robbery.

Both remain in custody.

The Winnipeg Police Service would like to thank the Nelson Police Department and the British Columbia Prosecution Service for their assistance.
