Two young children were seriously injured in a suspected DWI crash on FM 1960 in Harris County, according to Andrew Figliuzzi, an investigator with the Harris County District Attorney’s Office Vehicular Crimes Division.

Figliuzzi said some occupants of a vehicle struck in the crash were undergoing surgery for potentially life-threatening injuries. No deaths had been reported at the time of the briefing.

Figliuzzi also said there was probable cause to believe the driver who caused the crash was intoxicated. The driver is expected to face multiple counts of intoxication assault and could also face an aggravated assault charge.

A passerby was also detained after reportedly firing a rifle at vehicles following the crash. Investigators are working to determine why the person fired and whether they had any connection to the crash.
