Cuban revolutionary leaders eldest son fidelito commits suicide resembling father
I think there may be some misinformation here.
Fidel Castro's eldest son is Antonio "Ante" Castro Ruz, not Fidelito. Fidelito is actually Fidel Castro's son with his second wife, Dalia Soto del Valle. Fidelito's full name is Álvaro Miguel Fernández Santana, and he was born in 1962.
As for the claim that Fidelito committed suicide, I couldn't find any credible sources to support this. Fidelito is still alive, and there is no record of him taking his own life.
It's worth noting that Fidel Castro's family has been subject to various rumors and speculation over the years, which can be difficult to verify. However, I couldn't find any reliable sources suggesting that Fidelito committed suicide or that his death was in any way related to his father's passing.
If you have any further information or sources about this claim, I'd be happy to help clarify things.
