Despite Robison's comments, the jury found Perez guilty and she was sentenced to 25 years in prison, the minimum punishment for the first-degree felony, the Express-News reported. Robison removed himself during the trial's sentencing phase, the Austin American-Statesman reported in September.
The conviction was overturned and a mistrial was declared in October after a judge ruled Robison's rulings were not in accordance with the law and that he made partial comments toward the defendant during the trial, the Express-News reported.

In his self-report, Robison told the committee he was experiencing memory lapses at the time and was under extreme stress due to treatment for a medical condition and the death of a close friend.
