The Justice Department indicted leaders of the Sinaloa drug cartel who are accused of murder, torture, and other heinous crimes including feeding people both dead and alive to tigers. Those charged include sons of Joaquin Guzman Loera, better known as El Chapo, who is now serving a life sentence at a maximum security prison in Colorado.

“The Justice Department is announcing significant enforcement actions against the largest, most violent, and most prolific fentanyl trafficking operation in the world. That operation is run by the Sinaloa Cartel and fueled by Chinese precursor chemical and pharmaceutical companies,” Attorney General Merrick Garland said when making the announcement.

The nearly 30 defendants have been charged with fentanyl trafficking, weapons and money laundering, witness tampering and other crimes. The indictments target everyone involved in the fentanyl supply chain, from people making precursor chemicals in China, to manufacturers in Mexico, to those who distribute the final product.
