According to officials, whoever is behind the explosion used an altered pipe or stove to fill the house at 8349 Fieldfare Way in Richmond Hill with gas and then ignited it with a small spark, setting off a chain of explosions that destroyed a total of five houses and damaged 81 others.
A source told The Indianapolis Star on Tuesday that remote denotation was likely used in the November 10 which has been classified as a homicide this week.
The blast killed 34-year-old John Dion Longworth and 36-year-old Jennifer Longworth, who lived next door to the home which believed to have been was pumped with gas.
According to experts, the spark that set of the explosions could have been activated from the outside using a remote control commonly used to turn on an electrical device such as a TV or air conditioner.
Jay Siegel, a forensic and investigative consultant, told The Star that the detonation would have occurred when the concentration of gas inside the home reached 10 per cent.
The revelations come amid a flurry of rumors regarding arrests being made and suspects being taken in for questioning in the case that have since been disproved by top police officials.
Indianapolis police Captain Craig Converse said that investigators are currently busy interviewing people and following tips. Another law enforcement official said that two people were interviewed Tuesday, but neither was arrested or charged.
Police also said they served a warrant to obtain property, and another warrant to obtain fingerprints, but declined to identify the recipients of the two documents.
Investigators had taken into possession and inspected a white van that was allegedly spotted in the neighborhood on the afternoon of the explosion, but declined to reveal the identity of the vehicle’s owner or its connection to the case.
On Monday, authorities launched a homicide investigation into the case. Indianapolis Homeland Security Director Gary Coons made the announcement after meeting with residents of the subdivision where the November 10 blast occurred and just hours after funerals were held for the two victims.
