Authorities launched a homicide investigation Monday into the house explosion that killed a young couple and left numerous homes uninhabitable in an Indianapolis neighborhood.
Indianapolis Homeland Security Director Gary Coons made the announcement after meeting with residents of the subdivision where the Nov. 10 blast occurred and shortly after funerals took place for the two victims, who lived next door to the house where investigators believe the explosion originated.
“We are turning this into a criminal homicide investigation,” Coons said, marking the first time investigators have acknowledged a possible criminal element to the case.
Search warrants have been executed, and officials are looking for a white van that was seen in the subdivision the day of the blast, Marion County Prosecutor Terry Curry said. Authorities are offering at least a $10,000 reward.
Curry said the investigation is aimed at “determining if there are individuals who may be responsible for this explosion and fire.”
Neither he nor Coons took questions or indicated whether they had any suspects.
Officials have said they believe natural gas was involved in the explosion, which destroyed five homes and left dozens damaged, some heavily.
Investigators have been focusing on appliances as they search for a cause of the explosion, which caused an estimated $4.4 million in damage.
“It’s surprising that it finally came to that. Everyone had their suspicions,” Chris Sutton, who lives a street away from the blast site, said after attending Monday night’s meeting.
“It’s kind of scary that someone might set off a gas explosion,” he added. “It’s really scary.”
Hundreds of people attended the funerals earlier Monday for the couple killed in the explosion, 34-year-old John Dion Longworth and 36-year-old Jennifer Longworth.
She was a teacher remembered for knitting gifts for her students, while her husband, an electronics expert, was known as a gardener and nature lover.
