An Indiana State Trooper revived a Vincennes teenager Monday night following a moped accident in the 19-hundred block of College Avenue. Police say 18-year-old Arthur Johnson, who was not wearing a helmet, struck his head on the pavement after he lost control of his moped and it fell onto its side. Johnson was not breathing and did not have a pulse. Trooper William Campbell initiated CPR and a short time later Johnson began breathing again. Knox County EMS arrived and continued to care for Johnson. Johnson was taken to Good Samaritan Hospital and then flown to St. Mary’s Hospital in Evansville.
