HOUSTON - Charges against a driver have been upgraded following a crash from earlier this week in northwest Harris County.
Castro is also facing two counts of intoxication assault.
A man and woman were struck by a pickup truck on Barker Cypress and taken to the hospital in critical condition.
In a tweet, Sheriff Gonzalez reported that one of the victims in this DWI-related crash, Mayra Ospina, 23, has been declared brain-dead at the hospital.
Harris County deputies say multiple people were outside of their vehicles with their hazard lights on to check if anyone in a wrecked car needed help when Castro crashed his pickup truck into them and their cars on Monday.
A man and a woman were taken to the hospital in critical condition. Another person suffered broken bones.
