Mexicali municipal police arrested a 50-year-old American man wanted on a murder warrant in Riverside County, California, after responding to a routine disturbance call in the city’s Zona Oriente neighborhood.
The suspect, identified only by his first name Adolfo, is originally from Hollister, California. Officers detained him after a 911 call reported a man disturbing the peace. A standard background check during the detention revealed an active U.S. murder warrant tied to a homicide that occurred on June 28 in Riverside County.
Cross-Border Handoff at San Ysidro
Mexicali’s Dirección de Seguridad Pública Municipal, the city’s public safety department, coordinated with U.S. law enforcement agencies and Mexico’s National Immigration Institute (INAMI) to process the transfer. Officers transported the suspect roughly 120 miles west to Tijuana, where they turned him over to American authorities at the San Ysidro port of entry to face trial.
The arrest is the latest example of active fugitive cooperation along the Baja California border. In July 2024, Mexicali civil police apprehended Luis Contreras, a suspect in a 2005 Riverside homicide, after a cold case investigation by the Riverside Police Department’s Homicide Cold Case Unit and the U.S. Marshals Pacific Southwest Regional Fugitive Task Force. Contreras had been on the run for 19 years before his capture.
Baja California’s Role in Fugitive Operations
Baja California state and municipal police routinely run detained individuals through U.S. criminal databases. The state’s Fuerza Estatal de Seguridad Ciudadana (FESC) maintains a specialized international unit that works directly with U.S. marshals and the FBI on fugitive cases.
That unit gained national attention in April 2025 when its Tijuana-based “Gringo Hunters” team leader, Abigail Esparza Reyes, was killed during a shootout while trying to arrest an escaped California inmate. Esparza Reyes had led more than 400 operations to capture U.S. fugitives in Mexico over eight years.
In the current case, authorities have not released Adolfo’s last name or details about the Riverside County homicide. He now faces prosecution in the United States.
