A total of seven people have died on Saskatchewan roadways over the weekend.
The latest confirmed death involved a 20-year-old man on the Okanese First Nation.
File Hills First Nations Police say they believe the man was ejected from a vehicle in a Saturday afternoon rollover.
Two other occupants in the vehicle were transported to hospital while a fourth occupant fled the scene, but was later located.
RCMP are currently assisting in the investigation and police believe alcohol to be a factor in the incident.
The name of the deceased will not be released at this time and the investigation continues.
On Sunday, a four-vehicle crash at a construction zone on Highway 6 near Spalding killed three teenage boys and injured four other people — including a 21-year-old male flagperson who was airlifted to a Saskatoon hospital with critical injuries.
Elsewhere, a 15-year-old girl died and two other teenage girls were seriously injured when a pickup rolled on a grid road about 50 kilometres northwest of Swift Current.
A third accident left two people dead near Estevan when a semi and another vehicle collided, causing the smaller vehicle to ignite and burn beyond recognition.
In response to the fatal collisions, the Ministry of Highways called on Saskatchewan motorists to use extreme caution in construction zones as well as highways and roads.
