DOES ANYONE RECOGNIZE THE BRUNETTE? Photos of one of the main persons of interest in Christa's case. Patti (or Patty) Collins. Knew Christa between 75-77 in the Los Angeles area. Possibly in her mid to late twenties when she knew Christa. Might have had experience or ambitions in music, and her parents might have lived in Sacramento during this time. #patticollins #patriciacollins #pattycollins #christahelm
