“My Dad died working. He was at a work meeting and from there he was going to record a song,” Ventura’s son Jandy said in a press conference.

He added, “The Ventura family is proud of all the legacy my dad left. We have our heads held high. We are not ashamed of anything that he could have done. (I want) to tell the Dominican Republic and the world, that they lost the greatest exponent of the Dominican Republic’s music.”
