Update: it finally hit me. Jacquidon, Jackie and Don and pronounced as such. Sister of Kasi Peek, Dateline episode Deadly Omission. Murdered in 2005 ( seems so long ago now)

I remember seeing a true crime show (20/20 or 48 hours) and the episode had the sister of the victim on and she had a really strange name. It was like 2 names spliced together and not a name anyone else in the world would possibly have. I don't remember much of the case except that it was older maybe late 70s early 80s.
