LOUISVILLE, Ky. (WDRB) -- The massive explosion that destroyed a home in Jeffersonville on Sunday, killing a man and critically injuring his wife, was sparked by natural gas.

An investigation by the Jeffersonville Fire Department concluded that an increase in natural gas began flowing into the home on Assembly Road 12 hours before the explosion Sunday morning. According to a news release sent by the Jeffersonville Police Department on Tuesday evening, the flow of natural gas continued up until about 4:54 a.m. Sunday, when an "unknown source" ignited it and caused the explosion.

Vectren, an Indiana-based company that provides gas and electric service in the area, is taking part in the the investigation and has cut service to 14 homes in the area. Vectren has also shared the most current findings of its investigation with the Jeffersonville Police and Fire Departments. The company released a statement Tuesday night that said the "source of the natural gas involved in the incident appears to have been in the interior of the home, not on pipeline or infrastructure owned by Vectren."

Read the full statement below:

"Vectren, A CenterPoint Energy Company, wishes to extend its deepest sympathy to the families of those affected by Sunday morning’s incident. We would like to thank the first responders and community agencies for their service and support, including the Jeffersonville Fire Department, Jeffersonville Police Department and American Red Cross.

After being notified early Sunday morning, we activated our emergency response plan. Vectren crews immediately responded to the scene and made the area safe by turning off natural gas service to neighboring homes and evacuating the area. While the investigation is ongoing, it has now been determined the cause was natural gas. However, the source of the natural gas involved in the incident appears to have been in the interior of the home, not on pipeline or infrastructure owned by Vectren.

We will continue to work closely with all parties to ensure all facts and inputs needed to inform the investigation are provided. We will also continue to work closely with the Jeffersonville Fire Department and Jeffersonville Police Department as their investigation continues. We are assisting the American Red Cross as it coordinates shelter for those who are unable to return to their homes due to damage.

Vectren is committed to the safety of our customers, employees, contractors, systems and communities. Our goal is to deliver natural gas and electricity safely to the communities we serve. As a reminder to all Vectren customers, if you smell natural gas or suspect a natural gas leak, please call us directly at 1-800-227-1376 or call emergency response at 911."

The home explosion killed William "Billy" Phillips and sent his wife, Janet, to University Hospital in critical condition. Clark County Coroner Billy Scott confirmed Billy Phillips' identity Tuesday afternoon.

Two people who lived near the Phillips' home were also injured, but they're expected to survive, police said.

At least 12 to 15 other homes were damaged in the explosion. No foul play is expected.
