RCMP say alcohol is believed to be a factor in a rollover crash that killed a Whitewood woman and injured three others in southeastern Saskatchewan.

Police responded to a grid road one kilometre south of the Ochapowace First Nation at around 7 p.m. Tuesday.

A 28-year-old woman was pronounced dead at the scene. Her name has not been released. 

The 18-year-old female driver from Saskatoon and two others in the vehicle were taken to hospital in Broadview with non-life threatening injuries.

The cause of the crash is under investigation.
