INDIANAPOLIS — Mark Leonard, one of the people convicted for their roles in the 2012 Richmond Hill subdivision explosion, was found dead in prison Tuesday morning, a state correctional authority said.
Leonard, 48, was convicted in 2017 of conspiracy to commit murder for his role in the explosion. The blast left two people dead, and destroyed dozens of homes in the south side Indianapolis neighborhood.
Leonard died about 9:15 a.m. in the Wabash Valley Correctional Facility in southwestern Indiana, said Doug Garrison, chief communication officer for the Indiana Department of Correction. Online records Leonard had been incarcerated since Dec. 21, 2012.
Authorities were working to determine the cause of death.
Prosecutors said Leonard played a critical role in the conspiracy to rig the gas system and collect insurance money from the explosion of Monserrate Shirley’s home in the Richmond Hill subdivision. Leonard’s defense team said prosecutors did not provide credible evidence that Leonard had taken part in the conspiracy.
A jury convicted Leonard of offering $15,000 to having a witness killed before his trial began. Leonard was sentenced to 50 years in prison for attempting to hire a hit man to kill a witness. This was in addition to the two life sentences he received for his role in the deadly blast. Leonard lost an appeal in his case in October in the Indiana Court of Appeals.
