Excerpts from madison.com:
A search warrant reveals that a Wisconsin employee of USIC, an Indiana-based utility locating company with nationwide operations, failed to accurately mark the location of a gas line in the street. Instead, the worker marked a spot on the sidewalk approximately 25 feet away, where no gas line actually existed.
The warrant was issued to investigate the public street for evidence related to a second-degree reckless homicide charge in connection with the death of Sun Prairie Volunteer Fire Department Captain Cory Barr. He was killed on July 10 when natural gas leaked from a ruptured 4-inch line and ignited. Another firefighter, Ryan Welch, suffered critical injuries in the explosion.
The search sought electronic devices and data from equipment used during the underground boring operation at the time the gas line was struck. It also included items related to fiber communication conduits and sections of the gas line itself.
According to the search warrant affidavit, explosions occurred at buildings at 100 and 104 W. Main St. in Sun Prairie about 40 minutes after a gas leak was reported to 911. The blast destroyed properties ranging from 100 to 113 W. Main St., on both sides of the street.
Valentine Cociuba of VC Tech, a subcontractor for Verizon through Bear Communications, told investigators that Bear had informed him that the Diggers Hotline had been contacted on July 9. This allowed VC Tech to proceed with horizontal-directional boring along Bristol Street and Main Street.
Cociuba explained that work began after reviewing the markings made by USIC and developing a plan. However, in the southwest corner of the Bristol-Main Street intersection, he and other employees detected a gas smell and immediately called 911. He took a photo of the area before evacuating, which showed no "T" markings—indicating an intersecting utility like a gas line—on the pavement. Investigators later confirmed that there were no such markings above the point where the gas line was hit. Instead, a yellow painted "T" was found on the sidewalk about 25 feet to the north, but no gas line was located there.
A separate company was brought in to verify the gas line locations and confirmed the same findings.
State Department of Criminal Investigation Agent Ryan Windorff was provided a map by We Energies showing the actual gas utilities in the area. He noted that the gas line was located in the road, not on the sidewalk as incorrectly marked by USIC.
