There's a new reward tonight in the quest for the person who murdered a Duncanville great-grandmother.
Barbara Strain was shot and killed after answering a knock on her front door Wednesday morning. Her family was home at the time.
On Saturday, the reward was bumped up to $15,000 for an arrest and indictment in the case.
Anyone with information should contact Duncanville investigators at 972-780-5037.
