Leopoldo Esquivel, 34, was fatally shot near Valley Boulevard and Block Place in El Sereno, Los Angeles, on August 16, 2021. The Los Angeles County Medical Examiner-Coroner ruled his death a result of gunshot wounds. Family and friends remembered him for a vibrant personality and the joy he brought to those around him.

Investigators have tied Esquivel, known as Boxer, to Metro 13 and to a larger pattern of violence connected to a cache of guns stolen from a Union Pacific cargo train that had been looted by organized gangs. Multiple agencies, including the LAPD, LASD and the California Highway Patrol, have been involved in the investigation. More than 100 arrests were made in the cargo train thefts, though many charges were later reduced to misdemeanors or petty offenses, and prosecutions have faced challenges.

What details about Esquivel, his movements on August 16, 2021, or the stolen-gun trafficking would help move this case forward for investigators or anyone with information?
