A highway crash near Melfort, Sask., on Thursday has claimed the life of a fifth victim.

Melfort RCMP confirmed Friday that one of the two young girls taken to hospital Thursday afternoon has died, while the other remains in hospital.

Three other girls and a woman who was driving the sport utility vehicle died at the scene. According to the police, the SUV was travelling along Highway 41 and apparently missed a turnoff. The vehicle went into a farmer's field and flipped into a water-filled dugout.

Two passersby stopped to help bring some of the people in the SUV to the shore. Emergency crews needed a winch to pull the vehicle out of the water so they could remove the others.

The children, all between 7 and 10, are from St. Brieux, a community of about 500 located 180 kilometres northeast of Saskatoon. The people in the SUV had been on their way to St. Brieux from Melfort.

The five deaths have shaken the tiny community. People in town who spoke to CBC said they can't believe what happened and their hearts go out to the families.

"We're in complete shock," St. Brieux Mayor Pauline Boyer said. "There are no words."

A special mass was to be held in St. Brieux Friday at 7 p.m. to remember the people involved.
