'No cause has been ruled out' after deadly Indianapolis blast

At least two people are dead after a late-night explosion in an Indianapolis neighborhood.

Investigators are trying to puzzle out what caused an explosion and fire that killed two people and tore through a residential area of Indianapolis, displacing scores of residents, authorities said today.

The damage estimate is $3.6 million, said Adam Collins, Deputy Dir. of Indiana Code Enforcement.

The two deceased are adults, according to fire officials. Police as of 3 p.m. are not saying if a criminal investigation has been launched.

"There's a significant number of homes that have sustained damage, including two that have been completely destroyed. No cause has been ruled out," said Marc Lotter, a spokesman for Indianapolis Mayor Greg Ballard.

"The investigation is ongoing," he said. He added that seven people had been injured in the explosion, which left a large debris field. The origin of the blast was near 8415 Fieldfare Way, in the south part of Indianapolis, according to an Indianapolis Fire Department release.

U.S. Rep. Andre Carson, D-Ind., who represents the area, said he went to the church where the new donation headquarters is and area Homeland Security officials told him a bomb and a meth lab have been ruled out as causes.

The two homes exploded just after 11 p.m. Saturday, sparking fires in two others and damaging at least two dozen homes on the south side of Indianapolis, said Lt. Bonnie Hensley, a spokeswoman for the Indianapolis Fire Department.

"It looks like a war zone here right now," Hensley said.

Police have so far been unable to identify the two adults who died, a spokesman said this afternoon.

Jan Able, who lives nearby, said she believes the victims, a couple, lived in the home next door to where the blast occurred.

A woman in her 40s and her 12 -year-old daughter who live in the home where the blast originated  were in Ohio at the time, said Able.

Able's daughter and son-in-law live a few streets from Able, so she and her husband are staying with them.

Able said it’s a "very good neighborhood" full of professionals, including doctors, architects, nurses. 

The blast originated near 8415 Fieldfare Way, according to the fire department release.

From his bedroom a block away, 47-year-old software engineer Chris Patterson felt the walls of his home shake. The force of the explosion shattered a glass sliding door in his home, he said.

More than 100 firefighters responded to the two-alarm fire, according to a fire department statement.

Officials evacuated about 200 people to a nearby elementary school, where the Red Cross sheltered about 20 of them for the night. Others spent the night at friends' homes or with family, and officials planned to take the rest to the Southport Presbyterian Church.

As of late Sunday morning, approximately 60 cases of water and Gatorade were outside the school and a police spokesman said donations are pouring in, including toiletries, doughnuts and pizza.

Firefighters brought the fire under control by 12:30 a.m. Sunday but were still putting out hotspots afterward, Hensley said.

"It felt like something had hit our house,” Patterson said.
