SAN DIEGO – Federal prosecutors in the Southern District of California filed 135 border-related cases this week, 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 May 28, Leonardo Arturo Sandez Leal, a United States citizen, was arrested and charged with Importation of a Controlled Substance. According to a complaint, Customs and Border Protection officers at the Otay Mesa Port of Entry discovered 110 packages of methamphetamine weighing 125 pounds, and 10 packages of cocaine weighing 27 pounds, concealed in the rear quarter panels, floor, seats and center console of the vehicle the defendant was driving.
- On May 23, Jorge Luis Perez-Florez and Rumualdo Morales-Perez, both Mexican nationals, were arrested and charged with Attempted Bringing in Aliens for Financial Gain. According to a complaint, the defendants were intercepted by the U.S. Coast Guard off Point Loma with multiple undocumented Mexican nationals aboard their boat. Morales-Perez was previously deported to Mexico on March 20, 2025, through Laredo, Texas.
- On May 29, Noel Lopez Uribe, a Mexican national, was arrested and charged with Deported Alien Found in the U.S. According to a complaint, a Border Patrol agent discovered the defendant hiding near some brush in Otay Mesa. Lopez Uribe was most recently removed from the U.S. in April 2025.
Also recently, 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 a few of those cases:
- On May 30, Raul Diaz, a citizen of Colombia, was sentenced in federal court to six months in custody for attempting to re-enter the U.S. illegally. He was previously convicted in November 2014 of embezzling nearly $114,000 of public money.
- On May 30, 2025, Temo Duble-Chaparro, a Mexican national with no permission to enter the United States, was sentenced to 18 months in custody for illegal reentry of a removed alien, to be followed by a four month consecutive sentence for violating the conditions of his supervised release. This was the defendant’s fourth federal immigration conviction in as many years. He previously had been convicted of alien smuggling and illegal reentry.
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.
