DENVER – The U.S. Attorney’s Office for the District of Colorado announces that defendants Caesar Ramon Martinez Solis, 41, and Humberto Ivan Amador Gavira, 24, both of Mexico, were charged with Unlawful Possession of Ammunition by Alien Admitted Under a Nonimmigrant Visa.

According to the criminal complaint, on March 26, 2025, Detectives with the Fremont County Sheriff’s Office (FSCO) conducted a traffic stop of a vehicle occupied by defendants in Canon City.  Defendant Martinez Solis consented to a search of the vehicle. During the search, the Detectives found what they estimated to be approximately 150 boxes of .308 ammunition, and approximately 30 boxes of 7.62 ammunition.  Each box was labeled as containing 1,000 rounds. 

The investigation is being handled by the Denver Field Office of Homeland Security Investigations and the Fremont County Sheriff’s Office, with assistance from the Denver Field Office of the Bureau of Alcohol, Tobacco, Firearms, and Explosives.  The prosecution is being handled by the Violent Crime and Immigration Enforcement Section of the United States Attorney’s Office.

This case is part of Operation Take Back America, a nationwide initiative that marshals 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 (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).

The charges in the complaint are allegations and the defendants are presumed innocent unless and until proven guilty beyond a reasonable doubt.
