Not leaning either way, but there was a famous case about a lawyer in Guatemala who recorded a video message claiming he wasn't suicidal and that the government was out to kill him. He was killed days later and the video was released. The country was (briefly) thrown in to turmoil. A few days later it came out that he had ordered a hit on himself.
That article is an absolute hodgepodge of statements and retractions, but the same hitman appears to have also killed the laywer's clients, who were causing problems for the regime. That seems like pretty strong evidence that it wasn't a suicide by hitman, unless the lawyer also had his own clients killed?
