House Explosion Mastermind Mark Leonard Dies In Prison


Mark Leonard, the man convicted in the massive 2012 Indianapolis house explosion that killed two in the Richmond Hill subdivision, has died at the Wabash Valley Correctional Facility, a spokesman for the Indiana Department of Correction confirmed Tuesday. He was 48.

Leonard and his brother, Bob, were convicted on a slew of charges after they caused a natural gas explosion at the home of Monserrate Shirley, Leonard’s girlfriend. The explosion killed Shirley’s neighbors, Jennifer and Dion Longworth, and damaged or destroyed dozens of homes in the neighborhood on Indianapolis’ far south side.

Bob and Mark Leonard each were sentenced to life without parole. Shirley was sentenced to 50 years in prison.

Earlier this month, the Indiana Supreme Court ruled unanimously that Mark Leonard would not appear before them again after denying transfer to his challenge of one of his numerous felony convictions.
