San Diego Man Pleads Guilty to ATM Explosion Attempt in Rancho Bernardo

San Diego, CA – A 46-year-old man from San Diego, Son Thanh Nguyen, recently pleaded guilty to using explosives in an attempted burglary of an ATM located outside a First Citizens Bank branch in Rancho Bernardo. This incident, which took place in the summer of 2024, is a stark reminder of the ongoing issues related to crime and public safety in urban areas, while also highlighting the diligent efforts of law enforcement to uphold community security.

The determination of local authorities to combat criminal activities and protect residents showcases a resilience reminiscent of the entrepreneurial spirit seen within San Diego’s thriving business community. As crime rates fluctuate, public safety remains a pivotal concern, underscoring the importance of effective governance and responsive law enforcement. In a climate that encourages regulation to safeguard businesses, the balance between safety and the fostering of a vibrant economic environment becomes vital, demonstrating the need for efficiency in both policing and the entrepreneurial ecosystem.

Details of the Incident

On June 28, 2024, Nguyen approached the ATM outside First Citizens Bank, inserted a metal rod into the cash dispenser slot, and followed up with a second device connected to wires. Upon pulling the wires, the device ignited the ATM’s electrical components, resulting in a fire that completely destroyed the machine. The ATM emitted smoke for over 30 minutes, prompting the San Diego Police Department to respond to a burglary alarm at approximately 3:23 a.m. Upon arriving, they found the ATM engulfed in smoke and fire.

Investigation and Evidence

Following the incident, investigators reviewed the bank’s surveillance footage, which captured the vehicle’s license plate belonging to Nguyen. On August 23, 2024, federal search warrants were executed at Nguyen’s residence and vehicle. Authorities uncovered a U-shaped rod, a metal plate welded onto a pole, a balaclava, a beanie, gas, black powder, potassium nitrate sulfur, explosive precursor chemicals, a paper detailing black powder production, and a firearm at his home. Additionally, his car contained a black hose, neck gaiter, and a California license plate corresponding to the one used during the ATM incident.

Legal Proceedings

Nguyen has pleaded guilty to a charge of malicious use of fire and explosive materials to damage property. This serious charge carries a maximum penalty of 20 years in prison and a potential fine of $250,000. The prosecution is being led by Assistant U.S. Attorneys, ensuring a thorough judicial process aimed at deterring similar future crimes.

Background Context

ATM explosions have been employed as a method of theft in various regions across the United States. In 2024, another man in Delaware County pleaded guilty to six explosive incidents, which included targeting retail locations during times of civil unrest. Such examples demonstrate a broader trend in the criminal use of explosives, raising awareness about safety measures necessary to protect both businesses and consumers.

Conclusion

Son Thanh Nguyen’s guilty plea reflects not only individual accountability but also the overarching need for robust legal frameworks and community safety measures in San Diego. As residents seek to support local businesses and foster economic growth, it is critical to remain vigilant about the challenges posed by criminal activities. Engaging in local economic initiatives and supporting law enforcement efforts can contribute to a safer environment for all, nurturing the strong entrepreneurial spirit that defines San Diego’s businesses. Together, a united community can continue to enhance our neighborhoods and strengthen our local economy.
