City homicide detectives are investigating two unrelated deaths that occurred on Tuesday.
Early Canada Day morning, a woman died of a gunshot wound in an apartment in the first 100 block of Donald Street.
Police say around 3 a.m., a man was handling a 9mm handgun which was legally registered to him, when the victim grabbed at his arm and the gun went off.
The woman has been identified as Michelle Stobbe, 28, of Winnipeg.
John Elwood Cameron, 35, of Winnipeg faces several charges, including causing death by criminal negligence (firearm) and careless storage of a firearm.
He is being held at the Winnipeg Remand Centre.
Later in the evening, a double stabbing left one man dead and another in critical condition at about 10:15 p.m. near the corner of Main Street and Broadway Avenue.
The incident took place near the Via Rail station entrance to The Forks, but police cannot say whether either of the men were attending Canada Day festivities.
No arrests have been made.
The investigation is continuing by members of the Winnipeg Police Service homicide unit. Anyone with information is asked to contact investigators at (204) 986-6508 or Crime Stoppers at (204) 786-TIPS (8477).
