LAWTON, OK (KSWO) - A car flipped and killed a person overnight in Lawton. It happened just before one Wednesday morning on Rogers Lane near Fort Sill Boulevard. Police say the convertible flipped on its top into a ditch, killing the man behind the wheel. A woman in the car was taken by ambulance to a hospital. Her condition is not known. Police believe speed may have been a factor because it appeared the car may have taken a turn too quickly.
