A recent Associated Press investigation is raising serious questions about how federal authorities handled fentanyl investigations in New Mexico. According to a report published by PBS NewsHour, the Department of Justice’s internal watchdog has opened a review into whether Drug Enforcement Administration agents knowingly allowed fentanyl shipments to reach the streets while building larger drug trafficking cases.
For New Mexico residents, the story is important because it highlights the complicated balance between federal drug investigations and public safety, and it also shows just how aggressive federal authorities can be when investigating alleged fentanyl trafficking. If you or a loved one is facing an investigation like this, a federal crimes lawyer from Suzuki Law Offices can help.
What Happened?
The Justice Department Inspector General announced a review of DEA policies and wiretap investigations in which agents may have learned about fentanyl shipments before they occurred but chose not to immediately stop them.
This investigative tactic is sometimes described as allowing drugs to “walk.” Rather than immediately seizing the drugs, investigators may monitor a shipment in an effort to identify additional people involved in a larger trafficking organization.
The AP investigation found that DEA agents in New Mexico monitored significant fentanyl shipments between 2023 and 2025. One internal report reportedly detailed an instance in which agents allowed a shipment involving approximately 74,000 fentanyl pills to go unseized in an Albuquerque mobile home park.
The Inspector General’s review will examine whether similar tactics were used elsewhere and whether federal policies were followed.
Why Is the DEA’s Approach Being Questioned?
Drug investigations can be complicated. Federal agents may want to identify not just the person transporting drugs, but the suppliers, distributors, financial networks, and other individuals connected to a trafficking organization.
However, fentanyl presents a particularly serious public-safety concern because of how dangerous even small amounts can be.
One DEA whistleblower, Agent David Howell, criticized the practice, arguing that allowing fentanyl into communities in order to build larger cases can expose residents to unnecessary danger.
The controversy is also connected to a change in Justice Department policy. According to PBS NewsHour’s reporting, earlier federal guidance adopted in 2017 instructed agents to seize or otherwise prevent fentanyl distribution as soon as practicable. The policy was revised in 2024 to give investigators more discretion when allowing a shipment to continue could benefit a larger investigation.
What Does This Mean for People Facing Federal Drug Charges?
The investigation into DEA tactics does not mean that federal drug cases are automatically invalid or that someone charged with fentanyl trafficking will have their case dismissed.
However, federal drug investigations involve extensive procedures, including surveillance, wiretaps, confidential sources, controlled purchases, searches, seizures, and arrests. The way law enforcement obtained and used evidence can become extremely important in a criminal case.
For someone facing federal drug charges, an attorney may need to examine questions such as:
- How did investigators first learn about the alleged drug activity?
- Was a wiretap used, and if so, was it properly authorized?
- Did investigators have probable cause for a search or seizure?
- Were confidential informants involved?
- Did law enforcement monitor alleged drug transactions before taking action?
- Were search warrants properly obtained and executed?
- Did federal agents follow applicable DOJ and DEA policies?
- Was evidence obtained in violation of a defendant’s constitutional rights?
These questions can be particularly important in serious federal cases where the government has accumulated substantial evidence during a lengthy investigation.

Federal Drug Charges Can Carry Serious Consequences
Fentanyl trafficking is aggressively prosecuted at both the federal and state levels. Depending on the circumstances, a federal drug conviction can result in substantial prison time, particularly when prosecutors allege large quantities, prior convictions, or conduct resulting in serious injury or death.
Federal prosecutors also have access to significant investigative resources. A case may involve multiple law enforcement agencies, months or years of surveillance, intercepted communications, financial records, and information from cooperating witnesses.
That is why anyone under investigation or charged with a federal drug offense should take the situation seriously from the beginning.

What Should You Do If You’re Under Federal Investigation?
If federal agents have contacted you about alleged drug activity, you should speak with a criminal defense attorney before answering substantive questions or agreeing to participate in an interview.
Do not assume that you need to wait until you are formally charged before getting legal advice. An attorney can help you understand what stage the investigation is in and what steps may be appropriate.
The recent DEA controversy is a reminder that federal investigations can involve complicated investigative tactics and significant constitutional issues. Understanding how evidence was collected may ultimately be just as important as understanding what the government claims happened.

The Bottom Line
The Justice Department’s Inspector General review will determine whether DEA agents followed federal policies when they allowed fentanyl shipments to continue as part of larger investigations. For now, the review is ongoing, and it does not establish that individual DEA agents violated the law.
For anyone facing a federal drug investigation or prosecution, however, the story highlights an important point: the government’s evidence and investigative methods should be carefully examined.
If you or a family member is facing federal drug charges in Arizona, New Mexico, or elsewhere, speaking with an experienced federal criminal defense attorney as early as possible can help you understand your rights and the potential defenses available in your case.
