I also had a close family member who committed suicide shortly after going on Prozac -- this also happened nearly 30 years ago. His young son later went on Prozac himself (several months after his fathers suicide) and immediately started demonstrating bizarre disinhibited anti-social behavior (e.g., damaging property, stealing from friends, etc). He was immediately yanked off Prozac when he started articulating his own thoughts of suicide. The bizarre anti-social behavior improved after discontinuing Prozac.

For some people, Prozac is a very dangerous drug. It is fully deserving of its FDA black label warning (which it didn't have 30 years ago).
