A 35-year-old mother has drowned after the vehicle she was driving overturned in a lake at Hanna Park, according to Jacksonville Sheriff’s Office. Officers say her five-year-old child survived with a small air pocket in the car. Investigators say the woman was attempting to make a three- or four-point turn on the narrow road when the vehicle slid and overturned into the water. Investigators say there was very little air inside when they found it. First responders had to use a knife to cut through multiple airbags to pull out the woman and child. First responders spent more than an hour looking for the car — even using a helicopter in the serach to find it. An investigation is underway. Copyright 2019 by WJXT News4Jax – All rights reserved.
