What happened to Diahann Carroll's young husband that she married in the 70's?

Diahann Carroll married her second husband, businessman Vic Damone, in 1987, not in the 1970s. The couple divorced in 1996. Carroll had previously been married to artist and director Monte Kay in the 1950s and later to singer and actor David W. Wiggins in the 1970s, but none of these marriages involved a young husband in the 70s. If you meant her relationship with a different individual, please clarify for more accurate information.
