On March 26, 2025, what began as a simple traffic stop on a highway in Cañon City, Colorado, turned into a significant federal case with possible national security implications. Deputies with the Fremont County Sheriff’s Office pulled over a white GMC passenger van after noticing that the driver failed to dim the high beams and did not use a turn signal when turning into a gas station. The officers had no idea what they were about to discover.
Inside the van were two Mexican nationals, 41-year-old Caesar Ramon Martinez Solis and 24-year-old Humberto Ivan Amador Gavira. Both men presented nonimmigrant visas as identification, which explicitly prohibited them from possessing firearms or ammunition in the United States. When deputies asked to search the van, the driver gave them permission.
In the cargo compartment, deputies found what the U.S. Attorney’s Office later described as a shocking haul: 150 boxes of .308 caliber ammunition and 30 boxes of 7.62 caliber rounds. Each box contained 1,000 rounds, bringing the total to an astonishing 180,000 rounds of large-caliber ammunition.
According to the federal arrest affidavit, neither of the two men had permits for transporting such materials, nor did their visa status allow them to possess ammunition under any circumstances.
The Men Behind the Wheel
Martinez Solis told investigators that he and Amador Gavira, his brother-in-law, entered the United States from Mexico just one day before they were arrested. They first arrived in Denver, where they purchased the van, and then traveled to Salt Lake City, Utah, where they bought the ammunition. The ammunition was being transported back to Colorado. Martinez Solis claimed he believed the rounds were intended for Pueblo, Colorado, though he could not explain why.
According to the affidavit, “[Martinez Solis] further explained that he did not know the intent with the ammunition but that he believed it was destined for Pueblo.”
The men were formally charged with Unlawful Possession of Ammunition by an Alien Admitted Under a Nonimmigrant Visa. Solis was also cited for multiple traffic violations including operating an uninsured vehicle, failing to properly transport hazardous materials, and not using proper lighting on the vehicle. Both were turned over to Immigration and Customs Enforcement and are now being held in ICE custody.
Operation Take Back America
This case was immediately brought under the umbrella of Operation Take Back America, a Justice Department initiative aimed at targeting illegal immigration, transnational criminal organizations, and cartels. In a press release, federal prosecutors said the program is designed to “marshal the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations, and protect our communities from the perpetrators of violent crime.”
Though the two men have not been linked to any terrorist organization or cartel in the public record, the scale of the ammunition being transported and the fact that they were prohibited from possessing it has raised major concerns. Federal officials are still investigating the final destination and intended use of the ammunition.
A Broader Threat: The Lawlessness at the Border
This case adds fuel to growing concerns that lawlessness at the southern border could open pathways for more serious threats. When individuals are able to enter the United States and begin transporting thousands of pounds of ammunition with little to no oversight, it raises questions about what else might be moving across state lines unnoticed.
The situation becomes more alarming when placed against the backdrop of growing foreign espionage and infiltration efforts. Former FBI Director Christopher Wray warned before leaving office that the scale of Chinese espionage was overwhelming American defenses. He stated that “China’s hacking program is larger than that of every other major nation, combined.” Intelligence experts have estimated that as many as 600,000 individuals are involved in China’s global intelligence operations, which include not only government operatives but also civilians, academics, and cyber hackers.
In recent years, Chinese efforts have targeted everything from U.S. infrastructure to law enforcement wiretaps. This has led to widespread concern that the groundwork is being laid for potential sabotage or even preemptive strikes on U.S. systems in the event of a future conflict, particularly over Taiwan.
Ammunition and Espionage: Are They Connected?
While there is no direct evidence linking this case to China or its espionage network, the growing fear is that networks of illegal activity in the U.S. could eventually intersect with foreign actors. Intelligence officials have long warned that criminal groups involved in weapons or drug trafficking could be leveraged by foreign adversaries. Trafficking operations already exist. The only question is who might use them next.
Martinez Solis and Amador Gavira claimed that they purchased the ammunition legally from a Utah store and were merely delivering it to a third party in Colorado. But with 180,000 rounds of military-style ammunition, the scale and potential danger of such a delivery cannot be ignored. There are few legitimate civilian uses for such a massive quantity of large-caliber rounds.
If criminal groups or foreign powers wanted to seed violence, destabilize public order, or arm militant cells inside the U.S., this is exactly the kind of unnoticed operation that could serve their goals.
Federal authorities have so far treated this case as a violation of immigration and weapons laws. But in the broader context of rising foreign threats and increasingly porous borders, it could serve as a wake-up call. As the Department of Justice presses forward with Operation Take Back America, the public and policymakers alike should pay close attention.
When two foreign nationals can enter the country, purchase a van, buy a shipment of high-powered ammunition, and cross multiple state lines in less than 48 hours before being caught by sheer coincidence during a routine traffic stop, it reveals cracks in the system that are too dangerous to ignore.
ACZ Editor: These were assault rifle rounds, not handgun rounds. While we don’t know much about their motivations, but this certainly seems like they are arming an organized group. And I can’t think of anything good that can come of it.
