Controversy continues to swirl around El Chapo after the sudden murder of a federal judge who presided over his appeals. Judge Vicente Bermudez, 37, was shot in the back of the head shortly after leaving his home for a jog, according to The New York Daily News. The unmasked gunman quickly ran away after doing the hit.

El Chapo is currently in a federal prison on the outskirts of Ciudad Juarez, which borders El Paso, Texas.

El Chapo was arrested earlier this year.

Photos emerged on the net showing El Chapo in cuffs and in police custody.

A photo was also taken of the weaponry El Chapo had on deck.

Five people were killed and one marine was wounded in the operation. Six others were arrested.

El Chapo was nearly captured in October 2015 when Mexican authorities pinpointed his location in a mountain in northwestern Mexico. He suffered injuries in his leg and face during his escape in an ATV.

El Chapo was hiding at a ranch near Cosala in the rugged Sierra Madre Mountains in western Mexico, NBC News reports.

Marines reportedly raided El Chapo’s ranch hideout in helicopters, but were driven back by Guzman’s security forces. The Marines later entered the camp on foot and found cell phones, medication and two-way radios.

El Chapo escaped from a maximum-security prison outside Mexico City in July.

This followed the drug lord’s arrest in Mexico City in February 2014. Guzman was taken without incident in a U.S.-backed Mexican raid on a condominium tower in Mazatlan, Mexico, according to the New York Times.

El Chapo is alleged to be the billionaire criminal mastermind behind the notorious Sinaloa Drug Cartel that has funneled the streets of Chicago with 80 percent of the h—–, c——, marijuana and methamphetamine, according U.S. Drug Enforcement Administration as reported by Business Insider. The drugs have a street value of $3 billion.
