🎯IMPACT: The case highlights a new avenue of concern in migrant perpetrated crime, with Mexican drug cartels employing teenagers to carry out violent murder plots.
The Department of Justice (DOJ) has revealed that Mexico’s Sinaloa Cartel is using teenagers to carry out targeted assassinations in the United States. Andrew Nunez and Johncarlo Quintero, both 15-year-old members of the Mexican Mafia-affiliated Westside Wilmas gang, pleaded guilty on Thursday in federal court to murder and attempted murder charges in relation to an assassination plot ordered by the cartel.
Federal prosecutors detailed how the two teenagers—hailing from the greater Los Angeles area—were hired by the Mexican drug cartel to murder several targets in Chula Vista, California. The attacks resulted in one death and multiple injuries before the teenagers fled to Los Angeles.
The pair admitted to making two attempts in one day to eliminate a cartel target, first at a Chili’s restaurant and later at a luxury apartment complex where the target was allegedly residing. Court documents detail that on March 26, 2024, the teens drove from Los Angeles to Chula Vista to execute the hit. The first attempt at the restaurant parking lot failed after a gun jammed, and the teens then tried to strike the target with their vehicle. Later that evening, they returned to the target’s residence with an accomplice, Ricardo Sanchez, who was fatally shot by a family member defending the target.
According to the DOJ, the teens were promised $50,000 each for the assassination. Both admitted their goal was to gain status within the Westside Wilmas gang and exploit their status as minors to avoid harsher penalties. The family member who shot Sanchez was injured but survived.
