Waldron, who was shot once in the stomach, was taken to Baylor University Medical Center, where she underwent surgery. She died about noon Sunday.
Police do not believe Waldron was targeted.
"We don't know if it was someone that was possibly kicked out of the club or had had a problem at the club previously or if it was purely random," police homicide Sgt. Bruce McDonald said in Sunday's online edition of The Dallas Morning News. "We don't believe at this time she was picked out."
Police are seeking witnesses who may have seen the shooting or been driving south on Pearl when it occurred.
