who's the blonde actress in S4 E16 'Love Story'

i saw the episode 'Love Story' S4 E16, the one with Michelle Phillips guest starring as Hooker's love interest. She was attacked by a gang who stole her car, the gang consisted of 3 guys & a girl nick named 'Moonshine', i think they said her real name was Monica. Does anyone know who played the character? She had longish blonde hair & looked a bit like Lisa Hartman. I tried to find it in the cast list here for this episode but it doesn't appear to be included.
