Update and another angle: One deceased from a fatality accident involving a FedEx 18 wheeler in Duncanville, TX

Update:

Two wreckers were on the right shoulder getting ready to tow a car they were working on when a FedEx Truck started to pass a car in the right lane and collided with the wreckers and car. This caused the two tow truck drivers to be pinned under the wreckage. One wrecker driver was pronounced deceased at the scene and one was transported to hospital by Careflight. No one else was injured. No drugs or alcohol were believed to be involved and at this time no charges are pending.
