She was police informant and by mid-2258 was about to testify in court against Deuce (the only person on the station bold enough to testify against him). Unfortunately, he got to her first and used a Na'ka'leen Feeder to wipe her mind. She was rescued by security and taken to Medlab but it was too late to recover her thoughts. When Deuce was brought to trial, Garibaldi had nothing of which to get a conviction on him for his crimes. Reduced to barely more than a vegetable, she would have to be completely retaught everything as though she had just been born.
