CBP officers at the San Ysidro Port of Entry discovered a woman curled inside the modified gas tank of an SUV on March 7, 2026. An officer spotted a human foot protruding from the tank during a routine inspection. The woman, a Mexican citizen, was lying in a puddle of gasoline with chemical burns on her legs and feet, breathing through a water-soaked rag pressed to her face. She told agents she had been inside for roughly 90 minutes and was going to pay $10,000 to reach the United States.
The driver was arrested and charged with human smuggling for financial gain. The woman was hospitalized as a material witness. The story made local news for a day, then disappeared. But the gas tank is not an aberration. It is a data point in a massive, cartel-controlled industry that moves thousands of people across the Baja California border every month — an industry that has grown more expensive, more dangerous, and more sophisticated as enforcement tightens on both sides.
What Human Smuggling Costs in 2026
The price to be smuggled from Tijuana into the United States has roughly doubled in the past two years. Mexican nationals now pay between $8,000 and $20,000 per crossing, depending on the method and the level of risk the smuggler absorbs. The woman in the gas tank was quoted $10,000 — a mid-range price for a vehicle concealment at a port of entry, where the chance of getting caught is higher but the physical danger is lower than a desert crossing.
Central American migrants pay more. Guatemalans, Hondurans, and Salvadorans typically pay $16,000 to $17,000 for the full journey from their home country to the U.S. interior, though prices above $30,000 are not uncommon for routes that include air travel segments or forged documents. Chinese nationals face the highest prices — as much as $45,000 to $50,000 per person — reflecting the longer logistics chain and the higher perceived ability to pay.
U.S. intelligence officials have reported that smuggling fees now average around $20,000 per person across all nationalities, up from roughly $7,000 just a year earlier. The reasons for the increase are straightforward: enhanced border technology, more Border Patrol agents, the near-elimination of humanitarian parole and CBP One appointments under the current administration, and the aggressive deportation campaign that makes a failed crossing far more consequential than it was two years ago. Smugglers charge more because the job is harder. Migrants pay because the alternatives — staying in cartel-controlled Mexican border cities or returning to the conditions they fled — are worse.
How People Are Hidden
The gas tank is one of dozens of concealment methods that CBP officers encounter at ports of entry along the California-Baja California border. While drug smugglers have long used modified fuel tanks, engine compartments, and dashboard cavities to move product, using these spaces for people is more recent and more dangerous. A human body needs air, and gasoline fumes in an enclosed metal space can cause loss of consciousness in minutes.
But vehicle concealment is far from the only method. In July 2025, the San Diego Union-Tribune reported a new trend: ambulances being used to smuggle people through the San Ysidro crossing. Migrants were placed on stretchers, covered with blankets, and driven through the port of entry as if they were patients being transferred. In Zapata County, Texas, Border Patrol agents found 55 people hidden in a sealed compartment inside a produce trailer, with no ventilation and temperatures exceeding 100 degrees.
Stash houses on both sides of the border hold 40 to 50 people in single-family homes for days at a time while smugglers coordinate the next leg. These houses are now found in ordinary residential neighborhoods — not remote areas — making them harder for law enforcement to identify. Migrants in stash houses are often held against their will until the full fee is paid, and reports of assault and extortion inside these houses are common.
The Tunnel Network
Beneath the border between Tijuana and San Diego lies one of the most active smuggling tunnel zones in the world. Since the mid-1990s, approximately 95 tunnels have been discovered and decommissioned in the San Diego sector alone. In April 2025, Border Patrol’s Tunnel Interdiction Group found an unfinished tunnel stretching nearly 3,000 feet from a house in the Nueva Tijuana neighborhood to beneath the Otay Mesa Port of Entry. It was 42 inches high, 28 inches wide, ran 50 feet underground at its deepest point, and was equipped with electrical wiring, lighting, ventilation, and a rail system for moving cargo. Mexican authorities found that the entrance had been concealed under freshly laid floor tile.
Most tunnels are built primarily for drug trafficking, but human smuggling has been documented through the tunnel network as well. The tunnels represent an enormous capital investment — construction costs run into the hundreds of thousands of dollars — and they are controlled exclusively by the cartels. Independent operators do not build tunnels. The Sinaloa Cartel controls the majority of the California-Baja California smuggling corridor, and no one moves anything through a tunnel without cartel authorization.
BDN covered the Otay Mesa tunnel discovery in detail. That story is here.
The Maritime Route: Pangas Off the Coast
The most dangerous smuggling method in the Baja corridor is the maritime route. Panga boats — small, open-hulled fishing vessels with outboard motors — launch from beaches near Rosarito, Ensenada, and points south, then run north along the Pacific coast toward San Diego County beaches. The trips happen at night, without running lights, in boats that were never designed to carry 15 to 25 passengers in open ocean swells.
In fiscal year 2025, the U.S. Coast Guard recorded 490 maritime smuggling events along the California coast, resulting in 1,526 apprehensions. That represents a slight increase in people caught despite fewer total events compared to the prior year, suggesting the boats are being loaded with more passengers per trip.
The consequences are fatal. In May 2025, a panga capsized off the San Diego coast, killing three people with seven more missing and presumed dead. Five people were charged in connection with the smuggling operation. In November 2025, another panga launched from Rosarito with a full load of migrants. The engine failed in open water. The captain argued with crew about whether to turn back to Mexico. The boat capsized. Four passengers drowned. The alleged captain was charged months later.
In a single weekend in February 2026, the Coast Guard intercepted six vessels carrying a total of 82 migrants — five of them within a 90-minute span south of San Clemente Island. The pace of maritime interceptions suggests that the sea route is growing in popularity precisely because the land border has become harder to cross.
Who Controls the Crossings
Every major smuggling route along the U.S.-Mexico border is controlled by a cartel. No one crosses without paying, and no coyote — the term for the individual smuggler who physically guides migrants — operates without cartel permission. Senior Border Patrol agents have described this control as unprecedented in scope.
Along the California-Baja California border, the Sinaloa Cartel dominates. Its territory extends from the Pacific coast through the mountains east of Tecate and into the desert crossings near Mexicali. The cartel does not typically run the smuggling operations directly. Instead, it franchises the routes: independent coyotes pay a per-head fee — sometimes called a piso or crossing tax — to the cartel for the right to move people through their territory. If the coyote does not pay, the consequences are severe.
This structure means that even when a driver is arrested with a woman in his gas tank at San Ysidro, the cartel that authorized the crossing faces no consequences. The driver is replaceable. The woman will be deported. The cartel keeps whatever portion of the $10,000 it was owed, and the route stays open for the next customer.
Why People Still Cross
Border crossings without authorization hit a 55-year low in 2025, averaging just over 7,000 per month compared to 88,000 monthly in the same period the year before. The current administration’s elimination of humanitarian reception programs, the expansion of ICE detention to a record 66,000 detainees, and the climate of fear associated with the mass deportation campaign have all contributed to the decline.
But people are still crossing. Apprehensions increased 83 percent between July and September 2025, particularly in Arizona. And the Baja corridor remains active because geography favors it: Tijuana is a 20-minute drive from downtown San Diego, the busiest land border crossing in the Western Hemisphere processes over 50 million crossings per year, and the Pacific coastline offers an alternative when the ports of entry are locked down.
The migrants who still attempt the crossing in 2026 tend to fall into specific categories. Some are fleeing cartel violence in their home states and see no safe option in Mexico. Some have family members already established in the U.S. and are willing to pay any price to reunite. Some are economic migrants who calculate that even with the risk of deportation, the earning potential in the United States justifies a $10,000 to $20,000 investment. And some are victims of misinformation — told by smugglers that certain routes are guaranteed or that asylum is still available at the border when it largely is not.
The Human Cost
In 2024, the bodies of 108 presumed migrants were found near the border in New Mexico alone, most within 10 miles of El Paso. Arizona’s Sonoran Desert yielded 114 bodies in the same period. Nearly half of those who died in New Mexico were women, with the largest group being women between 20 and 29 years old. The leading cause of death was exposure — heat stroke, dehydration, and hyperthermia in summer; hypothermia in winter desert nights.
These numbers do not include those who die at sea, those who die in stash houses, or those whose remains are never found in the vast desert stretches between Mexicali and Arizona. The International Organization for Migration has called the U.S.-Mexico border the deadliest land migration route in the world.
The woman in the gas tank at San Ysidro survived. She was treated for chemical burns and released from the hospital. She is cooperating as a material witness in the case against the driver. She will almost certainly be deported. Whether she will try again — and at what price — is a question that the statistics cannot answer but the economics of the smuggling industry strongly suggest.
What This Means for Baja Residents and Visitors
For Americans living in or traveling through Baja California, the smuggling industry is largely invisible. The tunnels are underground. The pangas launch at 2 a.m. The stash houses look like every other house on the block. But the industry shapes the security environment in ways that affect everyone. Cartel control of border territory means that certain areas — particularly the Tijuana River channel, parts of eastern Tijuana near the border fence, and isolated stretches of coast between Rosarito and Ensenada — carry risks that have nothing to do with ordinary street crime.
The U.S. State Department maintains a Level 2 travel advisory for Baja California and a more permissive assessment for Baja California Sur. BDN’s breakdown of the current advisory is here. For a region-by-region safety assessment, see our 2026 Baja California safety guide.
The border wait times, the military presence at checkpoints, the Coast Guard helicopters over the coastline — all of it is connected to the same industry that put a woman inside a gas tank for 90 minutes on a Friday afternoon in March. Understanding how that industry works is the first step toward understanding the border itself.
