INDIANAPOLIS - A homeowner, her boyfriend, and the boyfriend's brother were charged Friday with murder and arson in a massive explosion that killed two people, destroyed five homes, and damaged dozens more in an Indianapolis neighborhood.
Monserrate Shirley, Mark Leonard, and Bob Leonard were arrested Friday and charged with felony murder in the Nov. 10 blast, Marion County Prosecutor Terry Curry said at a news conference. They also face felony arson and conspiracy charges and have been jailed without bond, Curry said.
Investigators determined that Shirley's home - at the epicenter of the blast that killed her neighbors John and Jennifer Longworth - filled up with gas after a gas fireplace valve and a gas line regulator were removed, Curry said. A microwave, probably set to start on a timer, sparked the explosion and flattened much of the Richmond Hills subdivision, he said.
