A North Chicago man has been sentenced to federal prison after pleading guilty to fentanyl distribution during an undercover investigation by the Lake County Sheriff’s Office.

On December 16, Alfredo E. Rollins, 47, pled guilty to distributing over 40 grams of fentanyl and was sentenced to five years in prison.

The investigation started in 2024, when detectives from the Lake County Sheriff’s Office Special Investigations Group (SIG) obtained information that Rollins was selling heroin laced with fentanyl in Lake County. The task force cooperated with the Bureau of Alcohol, Tobacco, Firearms, and Explosives’ Chicago Field Division.

During the investigation, undercover officers purchased over 115 grams of fentanyl powder and approximately 2,000 fentanyl-laced pills from Rollins, according to officials. Rollins was detained in North Chicago following the undercover purchases.

Rollins was arrested with more than 65 baggies of marijuana prepared for distribution inside his vehicle, according to authorities. A later search of his home turned up more than two pounds of marijuana, according to authorities.

Rollins was hauled into federal custody in June after an arrest warrant was filed.

What they’re saying: “Yet again, our Special Investigations Group investigated and arrested a dangerous offender who was selling a deadly drug in Lake County,” Lake County Sheriff John D. Idleburg said in a statement. “I cannot stress enough that SIG, comprised of federal and local law enforcement, investigates and arrests some of the worst drug traffickers in the region.”
