INDIANAPOLIS - New court documents just unsealed offer an inside look into the investigation in the immediate aftermath of the deadly south side explosion and provide new insights into one of the men suspected in the blast.
Special Section: Indy Explosion
Search warrants related to the probe of the Nov. 10 blast that killed two people and caused millions of dollars in damage were made public Wednesday.
The documents show that investigators immediately turned their attention to the owner of the home that exploded, Monserrate Shirley, and her boyfriend, Mark Leonard, and began gathering financial records, phone records and more.
Only two days after the explosion, investigators had determined that the microwave and fireplace were used in tandem to create the deadly blast, and they'd figured out that with the step-down regulator missing, it would take nine hours for the home to fill with the amount of gas needed to generate such an explosion.
The documents also detail an interview conducted with Joshua Leonard, the brother of Mark Leonard and the explosion's third suspect, Robert Leonard.
Joshua Leonard told police his brother Mark is addicted to money and has been conducting frauds since 1995.
The three suspects were in court Wednesday because prosecutors filed new murder charges, accusing the three of a knowing act.
