Homeowner among 3 charged with murder in huge Indianapolis house explosion that killed 2

Prosecutors have charged a homeowner, her boyfriend and his brother with murder after causing a massive house explosion last month that killed an Indianapolis couple and decimated their neighborhood.

Marion County prosecutor Terry Curry says Monserrate Shirley and the others were arrested Friday morning and charged with felony murder.

Shirley's attorney has said she and her boyfriend were away at a southern Indiana casino when the explosion happened Nov. 10 in the Richmond Hill subdivision on the city's far south side.

Authorities have said they believed the explosion was intentional and caused by natural gas.

The explosion killed Jennifer and John Longworth, who lived next door to Shirley's home. Five houses were destroyed and about 90 houses in the subdivision were damaged, costing an estimated $4.4 million.
