North Chicago Man Pleads Guilty to Federal Fentanyl Distribution Charges Following Undercover Investigation
A North Chicago man has pled guilty to federal fentanyl distribution charges following a lengthy undercover investigation conducted by the Lake County Sheriff’s Office Special Investigations Group (SIG).
In 2024, SIG — a High Intensity Drug Trafficking Area (HIDTA)–funded task force — launched an investigation into suspected fentanyl trafficking in Lake County. The investigation was conducted in collaboration with the Bureau of Alcohol, To***co, Fi****ms and Explosives, Chicago Field Division. Detectives received information indicating that Alfredo E. Rollins, 47, of North Chicago, was selling he**in laced with fentanyl within Lake County.
During the investigation, SIG detectives conducted multiple undercover purchases from Rollins. In total, detectives purchased more than 115 grams of a powder substance containing fentanyl and nearly 2,000 pills containing fentanyl.
Following the undercover purchases, Rollins was arrested by SIG detectives while inside his vehicle in North Chicago. At the time of his arrest, detectives discovered more than 65 baggies of cannabis packaged for distribution. A subsequent search of Rollins’ residence led to the seizure of more than two pounds of cannabis.
A federal arrest warrant was later issued, and Rollins was taken into federal custody in June of 2025. On December 16, 2025, Rollins pled guilty to the distribution of more than 40 grams of fentanyl and was sentenced to five years in federal prison.
Lake County Sheriff John D. Idleburg praised the efforts of SIG and its partner agencies, stating that the task force continues to target and arrest dangerous drug traffickers responsible for distributing deadly substances throughout the region. Sheriff Idleburg emphasized that SIG’s work plays a critical role in preventing overdose deaths, disrupting firearm and drug trafficking, and combating human trafficking.
Christopher C. Amon, Special Agent in Charge of the ATF Chicago Field Division, also highlighted the dangers posed by fentanyl, noting that each trafficker removed from the community significantly reduces the threat to public safety. He reaffirmed ATF’s commitment to continued partnerships with Lake County SIG and federal law enforcement agencies.
Rollins remains in federal custody.
