Ismael Zambada Sicairos, alias “El Mayito Flaco and/or Caballero,” identified as the second son of Sinaloa Cartel drug trafficker Ismael “El Mayo” Zambada Garcia, was designated by the Drug Enforcement Administration (DEA) as the “Fugitive of the Week.
Every Friday, the US anti-drug agency shares on its networks a publication with the hashtag “#FugitiveFriday,” in which it disseminates one of the many search cards from its list of most wanted men in the United States.
On June 23, it was the turn of Zambada Sicairos, the only son of Mayo Zambada, who, like his progenitor, has not yet faced any prison time and is also less known.
The DEA recalled that Mayo’s son, nicknamed “Mayito Flaco,” is wanted in that country for conspiracy to distribute a controlled substance. In the publication, attached is a link to Zambada Sicairos’ file, which describes some of his characteristics and shares a link to the US Marshals’ website so that, in case they have any relevant information that could lead to his capture, they can report it there.
According to the DEA, Mayo Zambada’s second son is approximately 1.75 centimeters tall and weighs between 79 and 80 kilograms. His date of birth, although not specified, is 1982, which would make him 41 years old, and he specifies Mexico as his country of residence.
In February, the DEA included his name on the fugitive list, revealing for the first time a photograph of him. Zambada Sicairos is the son of the drug lord and María del Refugio Sicarios Aispuro.

At least three of his brothers, as far as is known, followed in their father’s footsteps and ended up in prison, although they later reached cooperation agreements that allowed them an early release from prison.
In a complaint filed in September 2013 in the Southern District of California, marked as case number 14CR0658-DMS, to which Infobae Mexico had access, it was detailed that “El Mayito Flaco” participated in the transportation of considerable quantities of methamphetamine from Asia to Mexico.
Once the methamphetamine arrived in Mexico, Zambada Sicairos arranged for the drug to be taken to the US border and then through the United States for distribution. Finally, he saw to it that the proceeds from the sales returned to Mexico and were distributed among members and associates of the Sinaloa Cartel.
“He further caused drug proceeds to be collected from customers in the United States and laundered and transferred from the United States to Mexico and elsewhere for the benefit of members and associates of the Sinaloa Cartel,” the document stated.
According to DEA reports, Zambada Sicairos faces charges in the Southern District of California for narcotics conspiracy and attempt, under federal violations of Title 21 and Code § 846.
The extent of Mayito Flaco‘s involvement in the criminal organization run by his father is largely unknown. However, he is the only one profiled to succeed him in command of the organization as long as he remains at large.
