An Edmonton couple has died after a collision near Mundare.

Vegreville RCMP said they responded to a collision around 3:30 p.m. Saturday on Highway 16.

Investigators believe that a Ford Ranger pickup heading eastbound on the highway may have stopped on the shoulder of the road when a tow truck, also heading east, collided with it.

The collision pushed both vehicles into the south ditch near an adjacent treeline.

A 74-year-old man and his 78-year-old wife were pronounced dead on the scene.

The 39-year-old driver of the tow truck was taken to hospital with non-life threatening injuries.

The names of the couple have not been released.

Police said the incident was still under investigation.       

Mundare is 70 kilometres east of Edmonton.
