Prosecutors charged three people with felony murder today against in the Southside Indianapolis house explosion last month.
Monserrate Shirley, whose Southside home exploded, killing two of her neighbors, was charged, along with her boyfriend, Mark Leonard and his brother, Robert Leonard. They were taken into custody this morning, prosecutors announced.
Authorities say they released gas into the house and appeared to detonate it with a microwave oven. They had a failed attempt to blow up the house a week before the explosion.
Shirley had recently increased the insurance coverage on her house to $300,000, authorities said.
Police earlier had said they believed the explosion was caused by natural gas, detonated with a remote device.
In addition to two counts of felony murder, each of the defendants was charged with one count of conspiracy to commit arson, a Class A felony; 12 counts of arson, a Class A felony; and 33 counts of arson, a Class B felony.
Also, Shirley and Mark Leonard were each charged with an additional count of Conspiracy to Commit Arson, a Class B Felony.
The case qualifies for the death penalty or life without parole due to multiple deaths, authorities said.
