Excerpts from the journal times.com: A thorough criminal investigation into the cause of a devastating explosion that destroyed multiple buildings and claimed the life of a volunteer firefighter last July has concluded that no criminal activity was involved, according to Sun Prairie Police Chief Patrick Anhalt. The incident was traced back to a breakdown in communication between utility contractors and their subcontractors, which led to an underground gas line being incorrectly marked before the explosion on July 10. Abigail Barr, the widow of Captain Cory Barr, a volunteer firefighter with the Sun Prairie Volunteer Fire Department who died in the blast, filed a lawsuit on Thursday. She is holding VC Tech, Bear Communications, USIC Locating Services, and WEC Energy Group (known as We Energies) accountable for her husband’s death. Two other volunteer firefighters, Ryan Welch and Greg Pavlik, also filed personal injury lawsuits against the same four companies, alleging they were harmed due to the negligence of the contractors involved in the project. A newly released police report revealed that the failure to properly mark the location of a fiber-optic cable being installed by Verizon was due to a subcontractor pulling out of the project. As a result, the company responsible for marking the pavement on behalf of the subcontractor did not complete the task. When the work was handed over to another subcontractor, the Verizon contractor mistakenly believed that the utility locating had already been done. This misunderstanding led the new subcontractor to strike the gas line, causing the massive explosion that destroyed several businesses and injured multiple people, including Captain Barr. The state Fire Marshal’s Office, in its final report, stated that while they could not determine the exact cause of the gas ignition, they confirmed that the explosion originated near the Barr House, located at 100 W.
