The last page of this week’s guilty plea in U.S. federal court of Dairo Úsuga, alias “Otoniel.” Until recently, Úsuga was the maximum commander of the Gulf Clan, Colombia’s most powerful neo-paramilitary organization, and one of the country’s top narcotraffickers.

The 51-year-old boss accumulated immense power, controlling territory and penetrating his influence deep within Colombia’s state. But this page does not show the handwriting of a man who had to write very often in his life.
