A 46-year-old woman, seriously injured in an accident last week, has died.

The accident happened around 9 p.m. on November 6 on Yellowhead Trail near Winterburn Road.

Police said a recliner fell from the back of a pickup truck heading west on Yellowhead Trail.

The truck stopped and moments later the recliner was struck by a Toyota Corolla sedan driven by the 46-year-old woman.

His vehicle was then struck from behind by a Chevrolet Avalanche.

Police said the truck that lost the chair then fled the scene.

“Unfortunately, this collision illustrates the tragic outcome that can occur when a load is not properly secured,” said Acting Sgt. Jeffry Knull, of the Major Collision Investigation Section of the Edmonton Police Service, in a press release.

Police are still seeking information about the dark-colored, older model van.

“If anyone witnessed this collision, has dashcam footage of the incident, or knows the driver of the dark-colored truck, we encourage them to contact us as soon as possible,” Knull added.
