One of the world’s major cocaine kingpins, a co-founder of Colombia’s Cali Cartel that smuggled some $2 billion in drugs to the U.S., is seeking compassionate early release from a federal prison because of ill health. Gilberto Rodriguez-Orejuela, 81, is asking a Miami federal judge to let him return to his family in Colombia because he suffers from prostate and colon cancer. Rodriguez-Orejuela has served about half of his 30-year prison sentence under a 2006 plea deal.
