The RCMP have named the three people from Sorrento, B.C. who died in a crash near Rosetown, Sask., on Sunday.

They are Douglas Janzen, 47, and two daughters, Alli, 19, and Cassidy, 13.

Douglas and Alli died at the scene on Highway 7, about three kilometres west of Rosetown in west-central Saskatchewan, when their westbound car struck an eastbound sport-utility vehicle head-on. 

Cassidy was taken to Royal University Hospital in Saskatoon, where she died.

Also taken to hospital were Douglas's wife, Pat Janzen, and their son Cody, 16. RCMP say Pat Janzen is in critical condition, but Cody has been released.

According to police, it had been raining on the highway when the crash happened at around 12:20 p.m. CST.

The car attempted to pass a transport truck before colliding with the SUV. Visibility may have been impaired due to road spray from the truck, the RCMP said.

Two men in the SUV, ages 56 and 30, were taken to hospital with injuries. They're from Plato, Sask., but the names have not been released.

The RCMP said it received permission from family members of the deceased to release their names to the public.

People in Sorrento, a community of 6,500 in the B.C. interior, are grieving the deaths of the three Janzen family members, says Reuben Pauls, a pastor at the River of Life Community Church.

"Virtually every family is touched by this, absolutely — business community, sports community, school community," he said.

"They know everyone, and everyone knows them."

The Janzen family was attending a wedding in Saskatchewan at the time of the collision.
