Several members of the Los Chapitos Cartel were recently added to the U.S. Drug Enforcement Administration’s (DEA) list of the country’s most wanted drug dealers list. This comes a few months after the DEA announced charges against the Chapitos, one of the newer cartels on the Mexican drug cartel landscape.

Los Chapitos is a splinter group from the infamous Sinaloa Cartel, with a core leadership of the sons of former Sinaloa Cartel leader Joaquín Guzmán Loera, aka “El Chapo,” according to InSight Crime.

Following El Chapo’s arrest in 2016, internal feuding over who should take control of the organization led to the splintering of Los Chapitos, which wanted control of Sinaloa over their father’s former right-hand man, Ismael Zambada García, aka“El Mayo.” There has been fierce fighting and deaths in Mexico between the two sides, InSight Crime reported.

Los Chapitos is following in El Chapo's footsteps by becoming major international drug traffickers. The cartel seems to focus, especially on the synthetic drug trade, trafficking large quantities of drugs such as fentanyl and methamphetamine, according to InSight Crime.

Currently based out of the Mexican state of Sinaloa, Los Chapitos has a lot of activity and territory in the capital city of Culiacán. Thus far, it seems Los Chapitos is thriving in urban centers while El Mayo’s operations are thriving in the rural areas, InSight Crime reported.

Perhaps the most notorious person added to the DEA's most wanted drug dealers list is Oscar Noe Medina Gonzalez, who is the right-hand man of one of El Chapo’s sons, News Nation reported Sept. 4. He is a hitman charged with protecting the fentanyl export routes and assassinating rivals from other Mexican cartels. The U.S. government is offering a $4 million reward to anyone who can assist in his capture.

Also added to the list are two other Chapitos associates. They are Kun Jiang, a Chinese citizen who provides the Sinaloa Cartel with supplies used to make fentanyl, and Luis Javier Benitez Espinoza, who is one of the main fentanyl traffickers for the Sinaloa Cartel and is under the direct orders of Los Chapitos, according to News Nation.

“The Chapitos pioneered the manufacture and trafficking of fentanyl – the deadliest drug threat our country has ever faced – flooded it into the United States for the past eight years and killed hundreds of thousands of Americans,” DEA Administrator Anne Milgram said in an April 14 news release.

She also mentioned the DEA spent a year and a half infiltrating their network and that it is their goal to “dismantle every part of the criminal cartels that are killing Americans at record rates,” the release reported.
