FORT MYERS, FL – Roger B. Handberg, U.S. Attorney for the Middle District of Florida, announced today that Brown Dimas III, 27, of Lehigh Acres, Florida, has been sentenced to three years and one month in federal prison for knowingly and illegally supplying weapons to a dangerous Mexican drug cartel. The sentence, handed down by U.S. District Judge Sheri Polster Chappell, comes after Dimas pleaded guilty on August 4, 2022, to falsifying records in connection with the firearms purchases.
Dimas operated as a ‘straw purchaser’ between November 2018 and March 2019, systematically acquiring high-powered rifles from licensed gun dealers in Fort Myers and Cape Coral. Court records reveal the purchases weren’t for personal use. Instead, he acted on direct orders from the cartel, falsely certifying on ATF paperwork that he was the ultimate end user of the weapons. This deception allowed him to bypass legal safeguards designed to prevent firearms from falling into the wrong hands.
The scheme wasn’t confined to Southwest Florida. After acquiring the weapons, Dimas personally transported them to Laredo, Texas, where he handed them off to a known cartel associate. The motive? Cash kickbacks. Dimas profited from arming a criminal organization responsible for violence and instability south of the border. This case highlights the alarming ease with which criminals can exploit loopholes in the firearms system to arm themselves and their allies.
The trail of these illegally purchased weapons has been chillingly documented. Since late 2019, at least four firearms straw-purchased by Dimas have surfaced in Mexico, recovered by Mexican military personnel in or near Tamaulipas following violent clashes with suspected cartel members. These aren’t just guns lost in the system; they are weapons actively used in a brutal and ongoing conflict.
The investigation was spearheaded by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), with Assistant United States Attorney Simon R. Eth handling the prosecution. Authorities emphasize this case is part of Project Safe Neighborhoods (PSN), a comprehensive initiative aimed at reducing violent crime and gun violence by fostering collaboration between law enforcement and local communities. The Department of Justice launched a strengthened PSN strategy in May 2021, focusing on building trust, supporting community organizations, and prioritizing strategic enforcement.
While Dimas’s sentence represents a victory for law enforcement, it’s a stark reminder of the constant flow of illegal weapons across the border and the lengths to which cartels will go to obtain them. The ATF’s Tampa Field Division continues to investigate potential straw purchasers and disrupt the supply chain fueling violence in Mexico. The case serves as a warning: those who profit from arming criminals will face federal prosecution and significant prison time.
