Chula Vista, California – Two teenagers from the Los Angeles area faced federal court this week for their involvement in a Sinaloa Cartel-directed murder plot that began at a Chili’s restaurant parking lot.[1][2] The failed attempts in March 2024 left one man dead and others wounded, highlighting how cartels exploit young gang members to carry out violence across the border.[3] Federal prosecutors secured lengthy sentences by charging the pair as adults, sidestepping California juvenile laws.

Parking Lot Ambush Turns Chaotic at Family Restaurant

Andrew Nunez and Johncarlo Quintero, both 15 at the time, drove from Wilmington in Los Angeles County to a Chili’s in Chula Vista on March 26, 2024. The Sinaloa Cartel had tasked them with eliminating a rival linked to a Tijuana-based group after a drug shipment theft.[1] As the target exited the restaurant with his family, Quintero stepped out of the vehicle Nunez drove, fired a shot that struck the man’s legs, and watched his gun jam before more rounds could fire. Nunez then accelerated toward the fleeing target in a failed bid to run him down.

The pair escaped without completing the hit. The target survived his injuries. Prosecutors later described the episode as the start of a racketeering-aided attempted murder.[2]

Second Strike at the Target’s Home Ends in Gunfire Exchange

Hours later, in the early morning of March 27, the teenagers returned to finish the job. They enlisted 28-year-old accomplice Ricardo Sanchez and approached the target’s residence armed.[1] Sanchez knocked on the door while Quintero and Nunez opened fire indiscriminately toward anyone inside, creating what court documents called a “kill zone.”

A friend of the target answered and returned fire after sustaining gunshot wounds to his hand, arm, and face. He fatally shot Sanchez in self-defense during the exchange. The teenagers fled once more, leaving behind a scene of chaos that claimed their accomplice’s life.[3]

From Street Gang to Cartel Enforcers

Nunez, also known as “Shooter” or “Felon,” and Quintero, known as “Dumper,” belonged to the Westside Wilmas gang. This group maintains ties to the Mexican Mafia prison gang. The Sinaloa Cartel leveraged these connections to recruit the minors, aware that California law – specifically Senate Bill 1391 and Welfare & Institutions Code Section 707 – limited state prosecutions for those under 16, often capping sentences at age 25.[1]

The teens expected about $50,000 each for the hit. Their gang backgrounds included prior minor offenses and personal hardships, such as family losses and drive-by shootings, which defense attorneys cited as factors in their descent into violence.[2] Federal charges invoked the “provocative act” doctrine, holding the pair responsible for Sanchez’s death as a foreseeable result of their actions.

Court Path Leads to Adult Sentences

Local authorities initially handled the case as juveniles, but San Diego District Attorney Summer Stephan transferred it to federal court to pursue harsher penalties. After closed-door hearings, U.S. District Judge Todd W. Robinson approved adult prosecution. The defendants pleaded guilty in December 2025 to murder in aid of racketeering and attempted murder.[1]

On March 13, 2026, Judge Robinson sentenced each to 25 years in prison. “The Sinaloa Cartel, Mexican Mafia, Westside Wilmas, and similar gangs need to be put on notice that you don’t get a pass when you have a juvenile commit an offense like this,” the judge stated.[1] U.S. Attorney Adam Gordon emphasized the ruling’s deterrent effect: “No to the Sinaloa Cartel recruiting juveniles. No to the Mexican Mafia directing gangland hits in San Diego. No to a lack of consequences for juveniles who would do their bidding.”[3]

This case underscores the reach of cartel violence into everyday American settings, from suburban restaurants to quiet homes. As investigations continue – including indictments against three alleged Sinaloa associates – the sentences serve as a stark warning to gangs exploiting youth.[1] What measures should communities take to counter such transnational threats?
