Four people — including a 15-year-old boy — have been charged with second-degree murder in connection with the death of a man in Prince Albert, Sask.

Virgil Pelletier, 35, died of blunt-force trauma after being hit with an object at about 3 p.m. MT on Thursday, Staff Sgt. Bill Chow of the Prince Albert Police Service said.

Police were called to a home in the East Flat neighbourhood in the city's northeast for a report that a person had been assaulted with a weapon.

The same day, a heavily armed emergency response unit set up in an area not far from the home and appeared to take two people into custody.

On Sunday, Chow said three men, aged 33, 29 and 28 have been charged with second-degree murder in connection with Pelletier's death. A 15-year-old boy was charged with the same offence.

Three of the suspects were arrested on Saturday at the Mistiwasis First Nation, 70 kilometres west of Prince Albert.

Police didn't identify any of the suspects. The teen cannot be identified under the provisions of Canada's Youth Criminal Justice Act.

All four people charged are due to appear in court on Monday, Chow said.
