Indianapolis Man Connected to House Blast Insurance Fraud Scheme Convicted

February 29, 2016

An Indianapolis, Ind., man was convicted of murder, arson and insurance fraud on Wednesday for his role in a 2012 house explosion that killed two neighbors and devastated a subdivision in the southern part of the city.

Jurors convicted Bob Leonard, 57, on all of the more than 50 counts he was facing. Prosecutors said surveillance video, witness testimony and DNA evidence proved he was involved in the plot with his half brother and others to use natural gas and a microwave to blow up the house for $300,000 in insurance. He faces a maximum sentence of life in prison without parole.

The verdict came seven months after Leonard’s half brother, Mark Leonard, was convicted of being the mastermind behind the Nov. 10, 2012, explosion that also damaged or destroyed more than 80 homes. He was sentenced in August to two life sentences, along with 75 years in prison.

The home was owned by Mark Leonard’s girlfriend at the time, Monserrate Shirley, who testified earlier this month that Bob Leonard was brought into the plot after a first attempt to burn down her house failed in October 2012. Prosecutors allege the suspects planned to destroy the house by filling it with natural gas. A microwave apparently set to start on a timer sparked the blast.

The explosion destroyed the home and the house next door, killing her neighbors, Jennifer and John “Dion” Longworth. Shirley told jurors that when she asked Bob Leonard about the explosion that killed her next-door neighbors, he replied: “Oh well, they died. You were in it. You talk, we talk.”

Prosecutors presented 16 days of testimony during Bob Leonard’s more than month-long trial in Fort Wayne, where the trial was moved because of high publicity of the case in Indianapolis. Mark Leonard’s trial was held in South Bend.

Bob Leonard didn’t testify in his defense, and his attorneys called just two witnesses who were on the stand for about a half hour. Jurors began deliberating Tuesday.

Shirley, who testified against both men, has pleaded guilty to two conspiracy charges. She faces a 20 years to 50 years in prison when sentenced. Her cooperation also led to charges against two alleged co-conspirators, Glenn Hults and Gary Thompson, who face a joint June trial. Thompson faces two counts of murder and 47 arson-related counts, while Hults faces a charge of conspiracy to commit arson.
