Mexico’s most notorious drug kingpin will be stuck in solitary confinement for a while.

Lawyers for the US attorney’s office in the Eastern District of New York have filed a motion opposing Joaquín “El Chapo” Guzman’s request to have his confinement relaxed.

“Indeed, if there were ever a case warranting [special measure], it is this one,” the brief states.

The lawyers argue in a 40 page brief filed Tuesday that there is a “substantial risk” that Guzman’s contacts with other inmates could led to the death of people close to the case.

The also point out that El Chapo escaped twice from maximum security prisons and used bribes as a means to escape.

Guzman’s lawyers argued that the drug kingpin is under such strict security at Manhattan’s Metropolitan Correctional Complex that he hasn’t been allowed to make a “single telephone call, even to his attorneys” or his wife.

They also claimed that Guzman’s cell lacked a window or air conditioning.

In the motion, however, lawyers for the Eastern District said officials at the Manhattan facility have had adjustments because Guzman’s “meetings with his legal team are so lengthy and frequent.”

The lawyers also say that El Chapo’s cell included a window with frosted glass, two pieces of exercise equipment, and the ability to make requests such as bottled water.

The conditions would only be modified, they said, to allow El Chapo legal counsel and prescreened communications with his family.
