Deputies were called to a major accident in the 14000 block of West Hardy Road overnight when they found a vehicle in the water under a bridge, according to the Harris County Sheriff's Office.
The victim, identified as Philana Atkins, was found dead inside the car by medics, deputies said.
Atkins was southbound on West Hardy Road in a 2020 Chevrolet Trax when she left the roadway and struck the embankment, deputies said. The impact caused the vehicle to flip and land in the water below the bridge.
The HCSO Vehicular Crimes Division and divers with the Marine Unit were called to the scene Sunday morning.
