Women sentenced for methamphetamine trafficking in the Billings area

BILLINGS – Two women who trafficked methamphetamine were sentenced this week, U.S. Attorney Kurt Alme said.

Jenny Olivia Denny, 43, of Dodson, pleaded guilty in August 2025 to one count of possession with intent to distribute methamphetamine. She was sentenced to 48 months in prison, to be followed by 5 years of supervised release.

Mona Bonita Gonzalez, 44, of Billings, pleaded guilty in September 2025 to one count of possession with intent to distribute methamphetamine. She was sentenced to 60 months in prison, to be followed by 5 years of supervised release.

U.S. District Judge Susan P. Watters presided.

The government alleged in court documents that beginning in approximately 2023, law enforcement began investigating a drug trafficking ring based out of Mexico that was sourcing illegal narcotics to Wyoming, South Dakota, and Montana, including Billings.

On August 2, 2023, law enforcement officers served a search warrant at a Billings hotel room rented by Gonzalez. Law enforcement seized approximately 2.77 pounds of methamphetamine. Law enforcement determined in addition to the 2.77 pounds found, there were additional amounts of methamphetamine given to individuals in Billings for redistribution, including two pounds to Jenny Denny.

On August 3, 2023, agents served a search warrant at a home where Denny and two other women lived. Agents seized eight ounces of meth and $2,660 in cash.

Both defendants' phones were analyzed by law enforcement. Messages between Denny and a co-conspirator/supplier of meth, who is located in Mexico, were reviewed. In one message Denny’s supplier asked her if she was ready for another pound yet, and Denny responded that she was still waiting on money. Other messages indicate Denny was distributing meth in the Billings area. Gonzalez’s two phones showed messages between Gonzales and a co-conspirator/supplier of meth who is located in Mexico where Gonzales asked about more drugs and the supplier indicated the drugs were on the way.

The U.S. Attorney’s Office prosecuted the case. The DEA and the Eastern Montana High Intensity Drug Trafficking Area Task Force conducted the investigation.

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.
