FORT WAYNE, Ind. (AP): An Indianapolis man has been convicted of murder, arson and insurance fraud for his role in a 2012 house explosion that killed a couple and devastated a subdivision.

Jurors convicted 57-year-old Bob Leonard on Wednesday on all of the more than 50 counts he was facing. The jury began deliberating Tuesday.

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

Prosecutors say they plotted to blow up the home for $300,000 in insurance money. Prosecutors say testimony, surveillance video and DNA evidence proved Bob Leonard was involved.
