Gary Allen was originally charged with two counts of murder and three counts of arson in connection with the May 2011 fire at 1119 S. State St. that killed Anna Richards, 63, and Jerry Richards, 47.

Allen was hailed as a hero in the immediate aftermath of the fire, credited with helping pull the victims from the flames.

But it was later discovered that he had set the fire to get back at his landlord, police said.

"There had been some confrontation with the landlord, and the landlord told him to leave the house," said Marion County Deputy Prosecutor Ross Anderson. "He believed at that point by setting the house on fire, he would be getting back at the landlord."

As part of a plea agreement, murder charges were dropped in the case.
