FORT WAYNE, Ind. (AP): A jury has resumed deliberating whether a man is guilty of helping plot a 2012 house explosion in Indianapolis that killed a couple and damaged or destroyed more than 80 homes.

The jury in Fort Wayne was behind closed doors Wednesday morning after deliberating for about an hour Tuesday following closing arguments on the murder, arson and insurance fraud against 57-year-old Bob Leonard.

Marion County Deputy Prosecutor Mark Hollingsworth told jurors the explosion was no accident, while defense attorney Ted Minch argued prosecutors failed to prove Leonard was involved despite testimony from 150 witnesses.

Minch tried to discredit the testimony of Monserrate Shirley, the girlfriend of Leonard’s half brother and owner of the house that exploded. Minch says Shirley had the motivation to commit the crime because of financial problems.
