SUN PRAIRIE (WKOW) -- Still no word on what caused a Sun Prairie home to explode early Tuesday morning.
The blast killed 26-year-old Andrew Manley and hurt Steven Slack and his girlfriend Lindsey Stephany. Stephany was released from UW Hospital.
Stephany's father Jim told 27 News' sister station in Wausau that Slack remains in the hospital with a broken back.
Jim Stephany released a statement to our sister station, saying of his daughter, "One of the blessings here was that her injuries were much less severe than they could have been, but emotionally there is a lot of healing to do. It's such a traumatic event."
The funeral for 26-year-old Andrew Manly will be held this Sunday, Nov. 14, at Cress Funeral Home in Madison.
Thursday, Sun Prairie heating company Service Specialists released a statement saying they installed a new furnace at the home on Coral drive six days prior to the explosion. They did not have a permit to install the furnace. Sun Prairie Building Director Dennis Allen said when it relates to day-of service and safety, that may happen.
The company says they installed a new furnace after they discovered a cracked heat exchanger, which if left broken, Allen says can emit carbon monoxide.
Service Specialist's door was locked Friday, and when an employee came to the door, she had no comment for 27 News.
Sun Prairie Fire and Police Departments and the State Fire Inspector are in charge of the investigation. The Sun Prairie Police Department had no updates Friday. Department of Justice officials
Dennis Allen, Sun Prairie Building Director, says, "It could be a coincidence. No way will I say it had anything to do with the furnace. It may be a coincidence." He continued, "There could easily have been three or four gas appliances in that home."
Allen added, "It's an odd circumstance that the people that lived there hadn't recalled any gas smells for five days... I think we might be surprised when we find out what they think happened."
He says he considers Service Specialists a reputable company: one he's used to do work on city buildings and install his own furnace.
According to the Better Business Bureau and DATCP, Service Specialists had no complaints filed against them in the past four years.
Allen said he thought more information could be available by or around Thanksgiving.
