Construction worker David Earl Hyde was killed Feb. 20 when a large metal pipe rolled off a trailer and struck him.

According to the state patrol, the 38-year-old Missouri man was assisting in the unloading of large metal pipes from a trailer when a pipe weighing as much as 2,500 pounds landed on him. They said that Hyde died at the scene.

According to a statement from Ames, the contractor on the project, “the worker was delivering pipe to the project and a section of pipe may have rolled off the delivery truck when the worker unstrapped it.”
