That's one badly researched article. Reinaldo Fuentes was a drug trafficker for the Clan Del Golfo (aka Urabeños), which is a Colombian cartel and of which Dairo Antonio Usuga David was the former leader. Nothing to do with the Gulf Cartel based in Tamaulipas, Mexico.

For someone who skimmed millions of dollars, they went easy on him. As far as cartel videos go, this one was rather soft. Especially compared to that crap they pull in Mexico; a few months ago Cartel Del Noreste uploaded a video where they had captured a La Linea/Juarez Cartel member and they flayed the guy's head while he was still alive. The guy seemed to be drugged as well, but still stuff like that is just unnecessarily cruel and absolutely ghastly.
