Five men and two teenage boys face a charge of first-degree murder following the killing of a 54-year-old Regina man in the city earlier this week.

Regina police say Shawn Roderick Douglas was murdered either late Wednesday or early Thursday morning.

The police investigation began on Thursday with a potential crime scene, but no victim.

Police were called to the 200 block of Quebec Street North after a report of an unconscious male being put into a vehicle.

The vehicle was gone by the time police arrived.

Meanwhile, officers who were sent to a house in the 1600 block of Toronto Street found evidence at the scene indicating “a connection to the events on Quebec Street North”.

The subsequent investigation led to the arrest of the victim’s alleged killers, with the help of the Saskatoon Police Service.

It wasn’t until early Saturday afternoon that a Regina Police Service canine member discovered Douglas’ body in a rural area northeast of Regina.

The adult suspects have been identified as 18-year-old Aiden James Anaquod, 23-year-old Johnathon Nelson Peepeetch, 24-year-old Joshua Duane Wilson, 30-year-old Michael Shane McNab and 32-year-old Dennis Calvin Thompson, all from Regina.

The names of the other two accused cannot be released because they are aged 16 and 17.

All of the suspects will be making their first court appearances Monday morning in Regina.
