Three people have been arrested in the explosion on Indianapolis' south side that killed two neighbors and damaged dozens of homes, RTV6 has learned.

Monserrate Shirley and her boyfriend, Mark Leonard, who lived in the home, along with Leonard's brother, Robert Leonard, were arrested Friday on numerous charges, including murder and arson.

The couple, who lived in the home at 8349 Fieldfare Way along with Shirley's 12-year-old daughter, was visiting a Lawrenceburg casino the night of Nov. 10 when the blast rocked their Richmond Hill subdivision, leveling five homes and damaging dozens more.

The death penalty will be under consideration in the case, sourced told RTV6.
