The long-unsolved Tylenol killings will no longer be led by the FBI, a disappointment for those holding out for a justice, the Chicago Tribune reports.

The news comes near the 31st anniversary of the seven deaths of Chicago residents who ingested cyanide-laced Tylenol capsules in 1982.

The discovery of cyanide sent a shock wave across the country, leading to reforms in packaging for over-the-counter drugs.

The investigation is now under the leadership of the Arlington Heights Police Department.

“We’re still working the case,”  Cmdr. Mike Hernandez told the Tribune.
