Authorities are searching for a gunman who fatally shot a University of North Texas student following a New Year's Eve party.

Denton police say Sara Mutschlechner, 20, exchanged words with the occupants of an SUV while stopped at a red light early Friday morning, ABC News reported. Two or three rounds were fired into the woman's car.

Mutschlechner was shot in the head causing her to lose control of her vehicle and crash it into an electrical pole,the Denton Record-Chronicle reported.

Mutschlechner, who was her friends' designated driver, died Friday evening at a hospital.

The gunman was in a black Lexus SUV occupied by five or six men, and at least two of the men were attending a different New Year's Eve party.

"We're sure that a lot of people at the party would've recognized who was in that vehicle and maybe be able to tell us who they were," Denton police officer Shane Kizer told ABC News. "We've got a lot of people that we're wanting to talk with at this time."

One of the passengers in the vehicle's car suffered minor injuries.

Mutschlechner was a member of the Zeta Tau Alpha sorority. The group held a candlelight vigil.
