Las Vegas Woman Charged in Fentanyl, Firearms Conspiracy

A Las Vegas woman made her initial appearance in federal court on Wednesday for conspiracy to distribute fentanyl, a Schedule II controlled substance, and possession of two firearms in furtherance of a drug trafficking crime as a result of a Las Vegas Homeland Security Task Force investigation.

“Fentanyl is a deadly poison that is devastating our communities,” said First Assistant U.S. Attorney Sigal Chattah for the District of Nevada. “We will continue to use every federal resource to target, disrupt, and prosecute the networks flooding our streets with these lethal drugs and illegal weapons.”

“Fentanyl traffickers who use the mail to move deadly drugs into our communities should know there is no safe route and no hiding place,” said Deputy Special Agent in Charge Jonathan Sherwin for Homeland Security Investigations (HSI) Las Vegas. “Through the Las Vegas Homeland Security Task Force, HSI, the U.S. Postal Inspection Service, the Henderson Police Department and our partners will continue to intercept fentanyl, seize the firearms and cash that fuel these crimes and hold accountable those who endanger the public for profit.”

“The City of Henderson takes a strong stance against fentanyl and illegal drug activity,” said Henderson Police Chief Reggie Rader. “We do not tolerate these actions here or in the surrounding area, and we are proud to work alongside our local and federal law enforcement partners to help keep our residents and neighbors safe.”

According to allegations in the complaint, on September 21, inspectors with the U.S. Postal Inspection Service conducted a controlled delivery of approximately one kilogram of fentanyl to the residence of Olga Josefina Mexia. Upon delivery of the package, Henderson SWAT entered into the residence. During a search of the residence, law enforcement found bulk cash, fentanyl powder in bulk and individually packaged, and two firearms.

Mexia is charged with one count of conspiracy to distribute a controlled substance and one count of possession of a firearm in furtherance of a drug trafficking crime. A preliminary hearing is scheduled for October 7, before U.S. Magistrate Judge Brenda Weksler for the District of Nevada.

This case was investigated by HSI, the U.S. Postal Inspection Service, and the Henderson Police Department. The case is being prosecuted by Assistant U.S. Attorney Joshua Brister for the District of Nevada.

This case is part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion. The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of U.S. law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States. The Las Vegas HSTF comprises agents and officers with the FBI, HSI, DEA, ATF, IRS-CI, the Las Vegas Metropolitan Police Department, the U.S. Marshals Service, and Nevada Gaming Control Board with the prosecution being led by the U.S. Attorney’s Office for the District of Nevada.

A complaint is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
