RCMP say the suspect in a fatal shooting on a Saskatchewan First Nation was located after a firearm was discharged, and that the man was taken to hospital where he was pronounced dead.

At around 5 p.m. CST on the Ahtahkakoop Cree Nation, as Mounties were on scene investigating a shooting from earlier in the day, the firearm was discharged, police said.

A 59-year-old man was transported to Shellbrook Hospital, where he was pronounced dead.

RCMP officers said they did not fire their weapons.

Police said they believe the 59-year-old man is the suspect in the shooting death of a 56-year-old man earlier in the day, causing a lockdown in the community. Police are not releasing the identity of the two dead men.

The RCMP requested the Saskatoon Police Service to conduct an independent, external investigation into the circumstances surrounding the discharge of the firearm. The Saskatoon police will report the results to the Ministry of Justice and Attorney General.

RCMP said because this incident is being investigated by an external agency, they will be unable to provide further details at this time and will not be conducting any media interviews.

RCMP respond to calls about shots fired

Just after 11 a.m. CST, RCMP received several calls from people reporting a man discharging a firearm near the health centre on the Ahtahkakoop Cree Nation.

Police said a man wearing camouflage clothing was spotted near the area of the shooting and drove away on an ATV.

The area where the shooting took place was blocked off by police for several hours and residents of the community were urged to stay inside until it was safe to come out.

Shortly after the shooting, CBC News reached out to one local who said he was surprised at the violence.

"People generally get the gist of what went on, and I guess you could say [we're] in shock in the community," said Ahtahkakoop resident Gerry Greyeyes.

RCMP released few details about the shooting, but Greyeyes said news and speculation travel quickly in the small community.

"Everybody knows everybody else and rumours run rampant, so you don't know [if] what you're hearing is second-, third-, fourth-hand information, no matter how reliable that is," he said.

The Ahtahkakoop First Nation is located about 165 kilometres northwest of Saskatoon.
