Davyon wrapped his arms around the student’s abdomen and performed the Heimlich maneuver, a technique he had learned on YouTube after being inspired by his uncle, Wendell Johnson, an emergency medical technician. Davyon said he had wanted to be an emergency medical worker since he was 6. Now, watching the boy choke, he had a sense of what the job would require.He squeezed the boy’s abdomen once.Nothing.Another squeeze. The boy was still gasping for air.Finally on the third squeeze, the cap flew out.When emergency medical workers arrived, Ms. Dawkins said, Davyon kept asking the boy if he was OK. The boy recovered and was fine the next day, she said.“He acts like he’s about 80,” she said of Davyon. “He’s definitely an old soul.”Ms. Johnson picked up her son, who she said was a bit shaken up. They had church service later that evening, so they went home, rested and then got back on the road.That’s when life No. 2 was saved.It was about 5 p.m. when Ms. Johnson spotted smoke coming from a house.“I didn’t think nothing of it, but he was like, ‘No, Momma, this is a house on fire,’” Ms. Johnson recalled her son saying.She turned the car around, and there it was: a small fire near the back of the house.There were cars outside. The screen door was shut. It faintly smelled like burned wood. If people were inside, Ms. Johnson said, they appeared to be unaware of the growing fire. She honked her horn and called 911 as Davyon got out of the car, walked to the front door and knocked.
