The FBI is investigating the notorious Unabomber’s involvement in the Chicago-area Tylenol killings.

Ted Kaczynski, the man behind the mail bombings that spanned nearly two decades, is currently serving a life sentence in a Colorado prison. He claims he had no involvement in lacing Tylenol capsules with potassium cyanide, a crime that killed seven people in 1982.

In a letter filed to the U.S. District Court in Sacramento, Ted Kaczynski revealed that the FBI requested his DNA sample for their investigation of Tylenol poisonings. He disclosed this in an effort to stop a federal auction of his belongings — belongings, he believes, that may be able to prove him innocent.

CNN reports that, according to FBI spokeswoman Cynthia Yates, “Kaczynski has declined to voluntarily provide samples.” But in his letter, Kaczynski claimed otherwise and said he would provide the sample voluntarily “if the FBI would satisfy a certain condition that is not relevant here.”
