(INDIANAPOLIS) - Indianapolis city officials have ordered the first six of 29 damaged homes in the Richmond Hill Subdivision explosion to be torn down on Monday.
Four others will be inspected later and are likely to be added to the list later, bringing the total to 33. The last four are off limits to the inspectors for now, because they are evidence in what is being called a homicide investigation.
The deadly Indianapolis neighborhood explosion had to be triggered by more than just a single spark if natural gas was the source. That's according to Purdue University professor Sally Bane.
Bane is not involved in the investigation, but does research on gas combustion. She says natural gas is very hard to detonate, so an explosion as powerful as the one that rocked the city's south side would have to be sparked by more than just a furnace pilot light.
The case is being investigated as an intentional act.
