AUSTIN -- Day two of testimony is underway in the murder trial of a woman charged with killing a Huston-Tillotson University track star.
Fatima Barrie was stabbed to death outside a 5th Street club two years ago.
Kaitlyn Ritcherson faces first degree murder and aggravated assault with a deadly weapon charges in Barrie's death.
Ritcherson's first trial ended in a mistrial because of a dead-locked jury.
Tuesday prosecutors showed video of the aftermath of the fight where Barrie was killed.
The state says Ritcherson provoked people that night trying to get in a fight when she stabbed Barrie.
Ritcherson's attorney says she did it to protect herself, claiming Barrie lunged at her three times and hit her in the head.
Wednesday morning before lunch two witnesses took the stand. One witness was the doctor who worked on Barrie. The doctor, who did not want his identity publicized, testified that he had to stick his finger in Barrie's heart to plug the stab wound.
The second witness was at the club the night of the stabbing and is a friend of Barrie's. He testified to seeing Barrie raise her hand up like she was going to hit someone.
The defense brought in the transcript from the previous trial for Ritcherson and is challenging witnesses if their testimony varies at all.
Barrie and Ritcherson did not know one another.
Ritcherson faces five to 99 years in prison if convicted.
The trial is expected to last one week.
