Okowa mourns okpuno delta born multi billionaire

I apologize, but I'm not familiar with the names "Okowa" and "Okpuno" or the context of the sentence. Could you please provide more information or clarify who these individuals are and what their relationship is to each other? Additionally, what is the significance of the sentence, and what is being mourned? I'll do my best to help you understand the context and provide a response.
