SAN DIEGO – Federal prosecutors in the Southern District of California filed more than 100 border-related cases this week, including charges of transportation of illegal aliens, reentering the U.S. after deportation, deported alien found in the United States, and importation of controlled substances.
The U.S. Attorney’s Office for the Southern District of California is the fourth-busiest federal district, largely due to a high volume of border-related crimes. This district, encompassing San Diego and Imperial counties, shares a 140-mile border with Mexico. It includes the San Ysidro Port of Entry, the world’s busiest land border crossing, connecting San Diego (America’s eighth largest city) and Tijuana (Mexico’s second largest city).
In addition to reactive border-related crimes, the Southern District of California also prosecutes a significant number of proactive cases related to terrorism, organized crime, drugs, white-collar fraud, violent crime, cybercrime, human trafficking and national security. Recent developments in those and other significant areas of prosecution can be found here.
A representative sample of border-related arrests this week, includes:
- Mexican nationals Isay Edel Ramos-Chaparro and Omar Alvarado-Ignacio were arrested March 4, 2025, by El Centro-based U.S. Border Patrol agents and charged with crimes relating to their alleged attempt to cross illegally into the United States on motorcycles through a breach in the border fence in Mexicali. Both defendants had previously been deported after entering the United States illegally.
- On March 6, 2025, Jason Kristopher Lowe attempted to enter the United States from Mexico via the San Ysidro Port of Entry driving a BMW X5, bearing California plates. Lowe was arrested when two individuals, both of whom admitted to being citizens of China without lawful documents allowing them to enter the United States, were found inside a secret compartment in the undercarriage of the BMW.
- Fernando Medina Rodriguez, Gustavo Camacha Medina and Carlos Cardenas Medina – all drivers of separate tractor-trailers attempting to cross into the U.S. from Mexico at the Otay Mesa Port of Entry – were arrested on March 4, 2025, on drug importation charges. According to a federal complaint, all three were sent to secondary inspection around the same time, where Customs and Border Protection officials found hidden compartments containing a total of approximately 171 pounds of cocaine.
Federal law enforcement has focused immigration prosecutions on undocumented aliens who are engaged in criminal activity in the U.S., including those who commit drug and firearms crimes, who have serious criminal records, or who have active warrants for their arrest. Federal authorities have also been prioritizing investigations and prosecutions against drug, firearm, and human smugglers and those who endanger and threaten the safety of our communities and the law enforcement officers who protect the community.
The immigration cases were referred or supported by federal law enforcement partners, including Homeland Security Investigations (HSI), Immigration and Customs Enforcement’s Enforcement and Removal Operations (ICE ERO), Customs and Border Protection, U.S. Border Patrol, the Drug Enforcement Administration (DEA), the Federal Bureau of Investigation (FBI), the U.S. Marshals Service (USMS), and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), with the support and assistance of state and local law enforcement partners.
Indictments and criminal complaints are merely allegations and all defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
