BONNEY LAKE, Wash. (AP) — The mayor of Bonney Lake says it's unclear if highway contractors were following their own work schedule when a concrete slab fell from an overpass and killed a young family in a pickup truck below.

Mayor Neil Johnson issued a statement saying that according to a plan filed with the city, no demolition work was scheduled to occur Monday, when the accident happened. He says the contract for the work expressly requires the contractor to protect traffic from falling concrete and debris.

The work was part of a $1.7?million project to add lights and a sidewalk along Highway 410. The demolition plan called for the bridge to be cut into segments, with the sections removed by heavy machinery.

Josh and Vanessa Ellis and their 8-month-old son, Hudson, were killed in the accident.
