SIDNEY – An 80-year-old Waterville woman lost her life in a highway accident on slush-coated Route 23.

June Marshall was killed instantly Wednesday when a sport utility vehicle driven by her husband collided with a pickup truck, state police said. Joseph Marshall, 79, and passenger Joyce Simpson, 69, of Waterville, were treated for injuries at MaineGeneral Medical Center’s Thayer unit.

Police said the tires of the SUV apparently got caught in slush, and the vehicle slid into the path of the pickup truck. The driver of the pickup was not injured.
