A cop in L.A. named Brian Cappell got a call last month about a nine-month-old baby that was choking. And he just happened to be in the right place at the right time.
He was driving in his car about a block away when the call came in. And his chest-cam was on, so the whole thing is on video.
As soon as he heard where the little girl was, he floored it got there in less than a minute and the girl's older sister flagged him down.
Then he grabbed the little girl from her mom started hitting her on the back while holding her face-down in his other arm and saved her life.
Once she started crying, he knew she was okay. He says it was the best sound he's ever heard in his life.
They got to see each other again this past Monday when Brian received a commendation for it.
