CHICAGO (Reuters) - The Chicago office of the FBI is asking for DNA samples from "Unabomber" Ted Kaczynski in connection with an investigation into an unsolved 1982 crime in which seven people died after taking Tylenol capsules laced with potassium cyanide, FBI officials said on Thursday.

"As part of our re-examination of the evidence developed in connection with the 1982 Tylenol poisonings, we have attempted to secure DNA samples from numerous individuals, including Ted Kaczynski," said a statement provided by the Chicago FBI office.

"To date, Mr. Kaczynski has declined to voluntarily provide this sample.

The office said the investigation into the Tylenol murders continues. No arrests have been made and no charges have been filed.

Kaczynski is in a federal penitentiary in Florence, Colorado.
