Release son family detained ex president jonathans cousin declares

I think there may be some confusion here. As a conversational AI, I'm not aware of any specific information about a family member of a former president named Jonathan being detained, nor am I aware of any declaration from a cousin of the former president regarding the release of a son from detention.

Could you please provide more context or clarify which Jonathan you are referring to? Is this a real-life situation or a fictional scenario? Additionally, what is the nature of the detention and what is the reason for the release being declared?
