The victims and families involved in the Nov. 9 Sun Prairie home explosion filed a lawsuit against Service Specialists of Dane County.
Lindsey Stephany and Steven Slack, the homeowners and the family of Andrew Manley, who died from injuries sustained in the explosion, alleged it was the Service Specialists' work from the installation of a furnace days before the incident that caused the explosion.
Manley, a 26-year-old teacher, rented a bedroom from Stephany and Slack.
According to Service Specialists, neither they nor the company's attorneys have seen the civil complaint.
""The lawsuit will be vigorously defended as Service Specialists denies that there were any shortcomings in their work or that their work in any way contributed to the cause of the explosion,"" Service Specialists said in a statement.
Stephany and Slack were injured in the explosion. According to a statement, Stephany sustained less serious injuries and Slack is paralyzed from the waist down.
An investigation into the explosion is ongoing, and police have yet to determine the official cause.
