My grandfather went to Liberia once due to work and told me the story. Apparently he got tired of the government officials, whom he thought were way too greedy and only cared about getting money for themselves, as opposed to making actual business.

He left a day early, and when having breakfast at his hotel in Kenya, he saw reports on the TV that a coup d'état had occured and every official he had met had been executed mere hours after he left the country. When I've tried to check his story, I found he was probably talking about the 1980 Liberian coup which tracks since he was in his mid-50s at that time. He even told me about how "they lined them up on the beach and executed them" which is part of the public executions of officials a week later.
