Osiel Cárdenas Guillén, Former Leader of the Gulf Cartel, Denied an Amparo

Osiel Cárdenas Guillén sought an amparo to invalidate a criminal case against him for his alleged responsibility in the crime of carrying a firearm for the exclusive use of authorities. However, a federal court ruled to reject the former leader of the Gulf Cartel’s injunction.
It should be noted that, in Mexico, Osiel Cárdenas faces seven criminal charges, including money laundering, homicide, bribery, in addition to the aforementioned charge of carrying firearms for the exclusive use of the Armed Forces.

Reports indicate that the objective of the man nicknamed “El mata amigo” (The Friend Killer) was to stop the actions for which he was formally imprisoned in 2005, when he was accused of carrying a firearm.

It was in 2007 that Mexican authorities extradited Osiel Cárdenas Guillén to the United States. And it was in December 2024 that the former criminal leader was deported to Mexico after serving a reduced sentence in the land of the stars and stripes.

In other words, the case against Cárdenas Guillén was interrupted by his extradition to the US, but it can now continue after he was handed over to Mexico and held at the Federal Social Readaptation Center No. 1 Almoloya, a maximum-security prison better known as El Altiplano, in the state of Mexico.

On December 23, Cárdenas Guillén was formally arrested in Mexico.
