A HEROIC former Army medic has described how he saved a delivery driver’s life by performing CPR for 20 minutes at the scene of a serious crash. Scott Davies, 46, was visiting a friend’s home in Mersea Road, Colchester, on Saturday evening when he heard a “massive smash” outside. The personal trainer, who spent nine years as a paramedic with the Royal Army Medical Corps, rushed outside to see if he could assist. He said: “We were sat down and watching the TV and heard this massive smash and a horn continue to sound. “The junction is notorious for crashes and we have seen lots of little ones before but this was something different. I must have been out there within 60 seconds.”
