A South Huron woman has died, just three days after a serious three-vehicle crash in Dashwood on Monday.

Huron County OPP say Catherine Burdett, 65, passed away in hospital on Thursday.

Burdett was westbound on Dashwood Road when her Ford Escape crossed the center line and collided with an eastbound dump truck and then a pickup towing a camper.

Burdett had been airlifted to hospital with life-threatening injuries following the collision.

Police say a post mortem is scheduled for Friday.

An investigation into the collision continues and anyone with information is asked to contact provincial police or Crime Stoppers.
