He was the eldest of the four children of Alberto Anido and Sarah Serrano, both Spanish Mestizo.
At the time of his entry into show business, he was in college at the Ateneo de Manila University studying management.
The official reason, contemporaneously reported by the mainstream media of Manila, was that Anido shot himself.
However, immediately after his death, rumors quickly spread that Anido was actually murdered, and that such fact was covered up owing to the prominence of the personalities allegedly involved.
Suspicion fell on the family of an ex-girlfriend whose father was Minister of Defense Juan Ponce Enrile, a major figure in the regime of then-President Ferdinand Marcos.
