Twenty-three suspects, seven search warrants, 15 arrest warrants and an investigation that ran for 10 months. That’s the scale of the case the Williamson County Sheriff’s Office in southern Illinois revealed this weekend. Before dawn on Friday, the office’s tactical team raided homes in Herrin and the nearby village of Energy. The Williamson County Sheriff’s Office identified 23 people, including a 16-year-old, in a drug and firearms trafficking raid on Friday morning, November 6. Investigators say the case involved methamphetamine, other drugs and guns allegedly sold by people who were not legally allowed to have them.

The Southern Illinoisan was first to report the investigation. Regional TV stations, which also covered the sheriff’s office announcement, added more details.

Inside the Herrin and Energy Raids: 7 Warrants Served Before Dawn

The operation started early. Starting at 4:30 a.m., the sheriff’s office deployed its Special Response Team to execute seven search warrants along with 15 arrest warrants stemming from the investigation. Officials executed search warrants at six locations in Herrin, Illinois, and one in Energy, Ill.

According to the sheriff’s office, the raids were the end of a long undercover effort. During the investigation, deputies conducted surveillance and made dozens of controlled purchases of methamphetamine, other drugs and firearms. Investigators reported finding evidence of illegal drug sales and firearms trafficking involving convicted felons, the WCSO said.

Officials have said little about what deputies seized. Deputies recovered methamphetamine, other controlled substances and weapons but did not release quantities or say how many firearms were seized. No street value has been released.

Sheriff Jeff Diederich described the case as an effort to go after supply networks, not just individual users. Diederich said the investigation was aimed at the groups responsible for supplying illegal drugs throughout the area. In a statement he said that people involved in drug trafficking in the county “will be aggressively investigated, pursued and held accountable under the law”.

The Charges: Meth Delivery, Gun Sales and a Felon-in-Possession Count

Not all 23 people are in the same legal position. Diederich said the following 23 individuals have been arrested, charged, cited and/or identified for enforcement action. Some people appear on the list more than once. Those listed more than once were identified multiple times over the 10-month investigation period, Diedrich told The Southern.

The charges published in local coverage include:

• Firearms offenses: unlawful sale or delivery of firearms, a Class 4 felony, and possession of weapon as a convicted felon, a Class 3 felony
• Methamphetamine delivery: mostly charged as Class 2 felonies. At least one person faces a Class 1 delivery count.
• Possession: one person is accused of five separate meth delivery counts, plus possession of methamphetamine, a Class 1 felony; possession of drug paraphernalia, a Class A misdemeanor
• A juvenile: the 16-year-old faces a Class 2 meth delivery charge. DrugBusts.org does not name minors.

Everyone named in the case is presumed innocent. The charges are accusations, not findings of guilt.

What Illinois Law Says About Meth Delivery Penalties

Illinois handles methamphetamine under its own law, the Methamphetamine Control and Community Protection Act, separate from its general controlled substances statute. Under 720 ILCS 646/55, the felony class depends on the amount of meth. A person who allegedly delivers less than 5 grams of methamphetamine or a substance containing methamphetamine is guilty of a Class 2 felony. Delivering 5 or more grams but less than 15 grams of methamphetamine or a substance containing methamphetamine is a Class 1 felony.

Under Illinois sentencing ranges, a Class 2 meth delivery case carries 3-7 years in prison, and a Class 1 case 4-15 years in prison. Penalties rise sharply with weight. Delivering 15 to under 100 grams is a Class X felony, 6–30 years in prison, and up to $100,000 in fines or the drug’s value, whichever is more. At the top, 900 grams or more brings imprisonment of not less than 15 years and not more than 60 years.

Charging the meth counts mostly as Class 2 felonies suggests that most of the alleged sales were small, street-level amounts rather than bulk loads. For more on how prosecutors draw that line, see our explainer on what turns a drug arrest into a felony. Because these are state charges, they will be heard in Illinois court, not federal court. Here’s why federal and state drug cases play out differently.

Williamson County’s Long Fight With Methamphetamine

This sweep is the biggest of many meth cases the sheriff’s office has brought in and around Herrin over the past two years:

• In a 2024 case in Whiteash, deputies reported seizing 5.84 pounds (2651.1 grams) of Methamphetamine, a handgun and $30,582 US Currency. The sheriff’s office said that case was also part of a 10-month investigation which involves multiple states.
• In early December 2025, deputies searched a home on West Madison Street in Herrin that officials described as the focus of an active and extensive methamphetamine distribution operation.
• In August 2026, two Herrin warrants came on back-to-back days. For one of them, officials said information gathered during the investigation indicated the suspected drug activity could be connected to a broader distribution network.

Federal prosecutors have also brought cases here. In an earlier case from the U.S. Attorney’s Office for the Southern District of Illinois, eleven individuals are facing federal charges for distributing meth in Jackson, Massac, Perry, Saline and Williamson counties.

Where the Meth Comes From

National data shows why meth is still a priority for local police. The DEA’s 2025 National Drug Threat Assessment reports that the Sinaloa Cartel produces multi-ton quantities of exceptionally high-purity and -potency methamphetamine. It adds that seized meth has reached average purity levels reaching nearly 97 percent in 2025. The DEA also warns about mixed drugs. Recent data from the National Forensic Laboratory Information System (NFLIS) indicated one in four submissions of cocaine and one in eight submissions of methamphetamine also included fentanyl. Our guide to how fentanyl compares with heroin and carfentanil explains why that matters.

Illinois Overdose Deaths: The Statewide Picture

Overdose deaths in Illinois have fallen sharply, in line with national trends. The Illinois Department of Public Health’s December 2025 semiannual report counted 2,419 Illinois residents who died from drug overdoses in 2024. The department noted that the Illinois-specific fatality data for 2024 are preliminary. Numbers may change as cases are reviewed. Opioids still cause most of these deaths. IDPH reported that in 2024, there were 1,838 fatalities due to opioid overdose in Illinois. This represents a 35.6% decrease from 2023.

CDC figures, which are counted differently, are slightly higher. According to a USAFacts summary of CDC data, there were 2,531 overdose deaths in 2024 in Illinois. Rates also vary widely across the state. In 2024, the death rate for overdoses in Illinois ranged from 7.0 per 100,000 in Rock Island County to 47.8 per 100,000 in Vermilion County.

What Happens Next in the Williamson County Case

The sheriff’s office says the raid led to criminal prosecution efforts against all 23 people. Because the list mixes arrests, charges, citations and people only “identified for enforcement action,” some suspects may not yet be in custody. Others may get a court summons instead of being arrested. No court dates or detention rulings have been announced.

The adult cases will go through the Williamson County circuit court under state law. Defendants will have first appearances, prosecutors may formally file or change charges, and the cases may end in plea talks or trial. The 16-year-old’s case will go through the juvenile system, which keeps court records confidential.

The sheriff’s office signaled that more enforcement is coming. Diederich said the department intends to continue pursuing those suspected of drug trafficking and other serious offenses. DrugBusts.org will update this report as charges are filed and the cases move through court.
