INDIANAPOLIS The owner of a house that exploded in Indianapolis, killing two people and damaging dozens of homes so severely officials say they must be demolished, said Monday that a problem furnace could be at fault.

John Shirley, 50, of Noblesville, told The Associated Press that his daughter sent him a text message last week complaining that the furnace in the home where she lives with her mother and her mother's boyfriend had gone out and required them to stay at hotel.

But Shirley also said when he asked if the furnace had been fixed, his daughter said yes, and he wasn't aware of any additional problems until he heard from his daughter again Sunday morning.

"I get a text from my daughter saying `Dad, our home is gone.' Then I called my ex-wife and she said what happened," he said.

A source in touch with the couple told CBS Indianapolis affiliate WISH-TV that a member of the family had smelled gas in the house.

Citizens Energy, the natural gas supplier to the home, did not receive any reports about a faulty furnace at the home, but the homeowner wouldn't necessarily report such a problem to the utility, spokeswoman Sarah Holsapple said. And if the homeowner hired someone to fix the furnace, the contractor wouldn't need to tell the utility.

"It's too early to speculate that this might have been caused by a gas leak," Holsapple said at an afternoon news briefing.

Citizens Energy tested for gas leaks in the neighborhood but hasn't found any. She said crews were also testing lines that run from the gas main to the home and were testing the home's gas meter. She said the utility had no record of abnormal gas consumption in the home that exploded.

Investigators said they have not determined a cause for the Saturday night blast that sparked a massive fire, blew out windows, collapsed ceilings and shook homes up to three miles away. Public Safety Director Troy Riggs said the search for answers could take some time.

The blast forced about 200 people out of their homes in the once-tidy neighborhood of one- and two-story single-family houses.

Some were allowed to return Sunday, and others were able to retrieve a few belongings. But those whose homes suffered the most damage will never be allowed back inside, officials said. They have estimated about 30 homes will need to be demolished.


"I walked outside and all the houses were on fire," said Alex Pflanzer, who immediately woke up at the sound of the explosion.

Indianapolis code enforcement officials met Monday with homeowners at a nearby church to discuss insurance and demolition procedures and to make arrangements to take some to their homes for an hour to collect more belongings later in the day.

The blast flattened the house Shirley co-owns with his ex-wife and one next door that belongs to second-grade teacher Jennifer Longworth and her husband, John. The coroner's office has not yet identified the two people killed in the blast, but a candlelight vigil was held Sunday night at the school where Jennifer Longworth teaches.

Indiana real estate records show Shirley's house had been for sale for a year until it was taken off the market in March.

Why didn't the family call someone about the furnace or leak or whatever they thought it might be I find this to be very odd that the family was in a motel when this incident happened! I am very sadden for the two individuals who were killed but I am glad for those individuals who step up to help. God Bless those in their troubling times and god bless the police and fireman and to all those who came to help!

A small home near ours in Saginaw MI exploded some years ago due to gas build up inside from a gas leak. The elderly owner was killed in the explosion. It was a small home but our windows were damaged some 3 blocks away and the home with the leak completely exploded. It was hard to recognize any part of the home on the lot where it once stood, the home's timbers and bricks were propelled outward with such force. With a much bigger home, adequate time for gas buildup and greater room for it to accumulate, I would expect the results could be what was seen in this weekend's tragic events. God Bless those affected, may the help needed be secured for those who survived.

Kinda surprising more people where not killed by a blast of this magnitude. Sure looks like a natural gas explosion. Not sure what else could cause such a large blast.

What do I know? But it seems a bit far fetched that this amount of damage could be caused by a furnace.

You COULD have educated yourself into the energy potential in a cubic foot of natural gas in a proper concentration compared to, say, a stick of dynamite.

FYI, a cubic foot of natural gas contains 38.2 (or so) megajoules (MJ) of energy. A pound of TNT contains about 42 megajoules of energy. An 1800 square foot home, with 8 foot ceilings contains over 14,000 cubic feet of volume.

That means about seven tons of TNT equivalent explosive, give or take a few hundred pounds.

I suspect it was less gas than that, though. 7 tons of TNT going off in one location would have taken out far more than this thing did. So yeah, a furnace DEFINITELY could have done this if there was a gas leak.

The story said: ""It's too early to speculate that this might have been caused by a gas leak," ... Are they serious? As a journalist for many years I covered gas explosions in addition to living about a mile and a half from the gas line explosion in Edison, N.J., back in the early 1990s. Short of one of the military's biggest bunker buster bombs or perhaps a small nuclear explosion there's absolutely nothing else that could cause that much havoc.

I agree. All you have to do is look back to the Watts Riots. Gas explosions leveled whole city blocks. This is very reminiscent.

Something's not adding up here, if it was a natural gas explosion the officials should have already been able to make that determination. A explosion of the magnitude has defiantly already got the best experts investigating from FBI, More than Likely Homeland security, EOD and any other government agency that falls into this category. There's more too this than just an accidental explosion.

The design of the pilot light was known to cause just this type of explosion under identical circumstances. The home builder knew of the risk but did nothing. The utility company protested but desisted when a local government employee intervened at the direction of a politician. The defendant's jury of dwelling dwellers awaits a rationale for the award that is so obviously due. That was somebody's home.
