A mother and her 6-year-old child were killed by a fire nearby, and the story had a real impact on Hector Montoya. So he took the $300 he had saved and spent the money on smoke detectors.

"Saving a life is more important," Montoya said.

With the help of the Grand Prarie Fire Department, he installed more than 100 smoke detectors, mostly in the homes of elderly residents and people who reminded him of the tragedy he saw on the news.
