A little boy is being hailed a hero after discovering his house was on fire and alerting his family to run to safety. Tristan Cook, 9, was watching TV with his siblings when he smelled smoke. He got up, opened the door to the den and saw that the room was in flames. Tristan leaped into action and ran to the other room to alert his mom of the fire. The frantic moments were captured on a Ring camera. “Everyone came out unscathed,” Tristan’s mom, Tracey said.
