An investigation found that a silver or gray Honda CRV SUV may have triggered the deadly crash. Police released a surviellance photo of the Honda Thursday afternoon, hoping to generate some leads.

They believe the SUV might have forced a commercial vehicle in the right lane to swerve left and hit the dump truck.
