Deadly House Explosion May Not Have Been An Accident

Authorities have launched a homicide investigation into a house explosion that left one couple dead and several neighborhood homes uninhabitable. INSIDE EDITION reports.

An Indianapolis neighborhood is in ruins after a mysterious explosion that got national attention.

The scene was of shocking destruction, something out of a war zone. Buried under the rubble—the bodies of an elementary school teacher and her husband.

Now, a stunning revelation by investigators reveals that it may have been murder.  

“We can confirm tonight that there is an active homicide investigation in this matter,” authorities said.

Ground Zero for the explosion was the home of Monserrate Shirley, and her 43-year-old boyfriend. She spoke with WISH-TV before police revealed they had launched a homicide investigation.

“I don't blame myself for it but, you know, I feel horrible. I mean, people died,” she said.

She says she and her boyfriend were at a casino the night of the blast. Her daughter was staying with friends and even her cat was being boarded, and that's causing all sorts of speculation.

Her home, before it blew up, had been up for sale, but she failed to find a buyer.  She told investigators her boyfriend had recently changed the thermostat on the furnace.

“We all lost everything,” Shirley said.

The attorney for Monserrate Shirley and her boyfriend said they are "bewildered" that police now say this is a homicide investigation.

"They have been cooperating with the authorities and have answered each and every question,” he said.
