SUN PRAIRIE, Wis. — Court documents say a contractor failed to properly mark a natural gas line that was struck and caused a deadly explosion in downtown Sun Prairie last summer.
A search warrant recently unsealed in Dane County Circuit Court says an employee of USIC failed to correctly mark the gas line in the street and instead targeted a spot on a sidewalk about 25 feet away. The employee has refused to talk to investigators. USIC has not responded to messages about the warrant.
Firefighter Cory Barr was killed July 10 when a subcontractor placing a fiber communications lines underground for Verizon ruptured a gas line and triggered an explosion and fire. Firefighter Ryan Welch was critically injured. The blast destroyed six businesses and one home.
