(CNN)A Georgia ambulance driver has been arrested and charged with driving under the influence and second-degree homicide-by-vehicle after he crashed the ambulance he was driving, killing the dialysis patient he was transporting, according to authorities.

Kevin T. McCorvey, 34, was driving a private ambulance on West Campbellton Street in Fairburn just before 7:30 p.m. Friday when police say he veered off the shoulder of the road causing the ambulance to roll over into a ditch. A patient, Wilton Thomason Jr., 66, was in the back of the ambulance and was not restrained in any way, according to preliminary investigative findings of the Georgia State Patrol. He suffered fatal injuries, GSP said.
      A Fairburn Police officer wrote in an incident report that the officer stopped McCorvey and the other person who worked in the ambulance from getting an Uber to leave the scene and the officer reported smelling alcohol on McCorvey's breath. The officer called GSP to take over the investigation.
        When GSP arrived, troopers gave McCorvey a field sobriety test, and he was arrested, according to the incident report. The Fairburn officer wrote in the report that McCorvey admitted to smoking marijuana, taking Adderall and drinking a beer while driving the ambulance.
          Kevin T. McCorvey was charged with driving under the influence and second-degree homicide-by-vehicle.
          McCorvey was arrested, taken to Fulton County Jail and charged with DUI combination less safe, homicide by vehicle 2nd degree, failure to maintain lane and possession of an open container, according to GSP.
          The other ambulance employee in the vehicle during the crash has not been charged, according to police.
            On Monday, McCorvey made an initial appearance in Fulton County Superior Court, was assigned an attorney and was denied bond, according to court records.
            CNN has reached out to McCorvey's attorney for comment.
