SAN DIEGO – Federal prosecutors in the Southern District of California filed 95 border-related cases this week so far, including charges of bringing in aliens for financial gain, reentering the U.S. after deportation, 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 sample of border-related arrests this week:
- On July 6, Lorenzo Arturo Bernabe-Alejo, a citizen of Mexico, was arrested and charged with Deported Alien Found in the U.S. after a Border Patrol agent spotted him lying on the ground about a quarter mile north of the border near the Otay Mesa Port of Entry. According to a complaint, the defendant was previously deported on June 26, 2025, at the Calexico Port of Entry.
- On July 7, Luis Fernando Ramos-Mendez, a Mexican citizen, was arrested and charged with Bringing in Aliens for Financial Gain and Aiding and Abetting. According to a complaint, a Customs and Border Protection officer found an undocumented Mexican immigrant hiding in a modified rear bench seat compartment near the trunk of the defendant’s car as he attempted to cross at the San Ysidro Port of Entry.
- On July 7, Refugio Ramos Daniel, a Mexican citizen and lawful permanent resident of the United States, was arrested and charged with Importation of a Controlled Substance. According to a complaint, a Customs and Border Protection officer found 198 packages containing 200 pounds of methamphetamine concealed in a non-factory compartment in the bed of the defendant’s truck as he tried to cross the border at the San Ysidro Port of Entry.
Also this week, a number of defendants with criminal records were convicted by a jury or sentenced for border-related crimes such as illegally re-entering the U.S. after previous deportation. Here are some of those cases:
- On July 7, Eliseo Gonzalez Chaidez, a citizen of Mexico who previously was convicted of a federal immigration and a drug trafficking crime that resulted in an eight-year sentence, was sentenced in federal court to 24 months in custody for illegally reentering the United States.
- On July 9, Francisco Ramirez, a Mexican national, was sentenced in federal court to 36 months in custody for conspiring to distribute methamphetamine.
Pursuant to the Department’s Operation Take Back America priorities, 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.
