VIDEO: Today, the Richmond Hill subdivision looks like a typical south Indianapolis neighborhood. But longtime Hoosiers will never forget what happened here 10 years ago.
An explosion in a home rocked Richmond Hill on Nov. 10, 2012, killing Jennifer and Dion Longworth, who lived next door. There were heroes that night, including a family who heard and felt the blast.
Dozens of homes were damaged in the blast. Thirty houses would eventually be torn down. As neighbors began cleaning up and rebuilding, investigators would comb through the debris in Richmond Hill looking for clues.
It was not an accident. Police said the blast was intentionally carried out by the ringleader, Mark Leonard. Prosecutors said the plot centered around insurance money. Monserrate Shirley, who lived in the home that blew up, denied any wrongdoing.
