Investigators say she was driving along the I-45 feeder road just before 4:30pm when for some reason, she veered off the road, jumped the curb, hit construction pipes and rolled about 100 feet into the water.
Five witnesses tried to jump into the water to get to her, but they couldn't because the windows on her vehicle were rolled up.
"Witness stated that he got out of the water around 4:35, 4:36 and they just pulled her out just a little after 5pm, so she had been in the water the whole time," said a deputy at the scene. "After that, the EMS did get a pulse on her."At this point, we don't know why she veered off the road.
