All of this was unnecessary, ol boy should've just got another wife and moved on. If his best asset was a path to US citizenship he could have used that. Get a new cuter wife, a younger wife, a wife with better qualifications from the jump, a more mature wife that was better established in a well-paying field. There were many lanes that would've matched his speed to choose from. Matter of fact, with the internet he wouldn't have been limited to Cameroon, even though for giggles he could have searched for a new wife in his ex-wife's hometown. The new wife is coming to meet zero assets, so if they split and they divvy their assets in half, guess what happens?
He could've have done some serious slow soul burning and fukkery for decades on the gram posting all kinds of pics with his new bae and their glamourous life. But now he's dead and the children may end up in foster care with God knows who.
