A 71-year-old man involved in a four-car wreck at NW 122 and Meridian died Friday afternoon at a hospital, Oklahoma City police said.
Norman Casey apparently had a medical episode and lost consciousness before crossing left of center as he was eastbound on NW 122, Sgt. Jennifer Wardlow said.
Casey's vehicle sideswiped two cars and hit a third vehicle head-on.
Wardlow said witnesses saw a man slumped over the wheel as his vehicle went left of the centerline.
Casey was taken to OU Medical Center where he died at 2:05 p.m.
The people in the other vehicles were not seriously injured.
