Kim RichardsNineteen years ago, 'The Real Housewives of Beverly Hills' star Kim Richards seemed to have it all. After finding success in films like Disney's 'Escape from Witch Mountain,' she met and was soon engaged to commodities salesman John J. Collett.

"She loved him and he loved her and it was like a fairy tale," his sister, Nina Stormo, told PEOPLE exclusively.

But in October 1991, her world shattered -- Collett was gunned down by a hit man outside a San Fernando Valley deli.

Richards had to identify Collett's body. Before his death, Collett had worked for a commodities firm that allegedly defrauded millions from investors, and many suspect his death may have been the result of a business scheme gone horribly wrong.

"It just tore her apart emotionally and she was not in good shape for a long time," Jan Collett, John's mother, told PEOPLE. "She really loved John. They were a good match."
