A 30-year-old man from Saskatchewan who was injured in a head-on crash near Rosetown, Sask., that killed three people from British Columbia has died in hospital.

RCMP said the man died from his injuries at Saskatoon's Royal University Hospital on Monday at about 5 p.m. CST.

The crash happened on Sunday at about 12:20 p.m. Police said it had been raining on the stretch of Highway 7 near Rosetown when the crash happened.

A car containing a family of five from B.C. had tried pass a transport truck before crashing into a sports-utility vehicle. According to police, there may have been poor visibility due to road spray from the semi.

The 30-year-old man who died in hospital Monday had been in the SUV along with a 56-year-old man. Both men were from Plato, Sask., but their names have not been released. The older man remains in hospital.

Killed in the crash were Douglas Janzen, 47, and two daughters, Alli, 19, and Cassidy, 13.

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