Mirriam Runningdear was a Human that ran a shop in Red 26 on Babylon 5.
She was a police informant and by mid-2258 was set 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. Reduced to barely more than a vegetable, she would have to be completely retaught everything as though she had just been born.
When Deuce was brought to trial, Garibaldi had nothing of which to get a conviction on him for his crimes.[1]
