DENVER (AP) – Texas authorities say it will be several more weeks before a grand jury deliberates the car accident involving Colorado state Sen. Suzanne Williams that resulted in the death of a pregnant woman.

Trooper Gabriel Medrano told The Denver Post that investigators were forced to postpone their work reconstructing the accident because of recent snowstorms. A grand jury cannot hear the case until the Texas Department of Public Safety finishes its inquiry into the Dec. 26 crash.

Authorities say Williams, who represents Aurora, was driving a Honda CR-V that drifted into oncoming traffic and collided with another vehicle, killing 30-year-old Brianna Gomez of Amarillo. Gomez’s son was delivered at a hospital and survived.
