Ted Kaczynski: The Unabomber’s Bombings, Manifesto, and Capture

Ted Kaczynski, known as the Unabomber, was a reclusive former mathematics professor who carried out a seventeen-year mail-bombing campaign that killed three people and injured more than twenty others before his younger brother recognized his writing in a published manifesto and turned him in. He pleaded guilty in 1998 to avoid the death penalty, received four consecutive life sentences plus thirty years, and died by suicide in a federal prison medical center in June 2023 at the age of eighty-one.¹

From Harvard to a Montana Cabin

Theodore John Kaczynski was born on May 22, 1942, in Evergreen Park, Illinois. He enrolled at Harvard University at sixteen and finished his undergraduate degree in 1962. He went on to earn a PhD in mathematics from the University of Michigan in 1967 and took an assistant professorship at the University of California, Berkeley, the same year. He resigned from Berkeley in 1969 without explanation.²

In 1971, Kaczynski and his brother David bought a piece of land near Lincoln, Montana. Ted built a ten-by-twelve-foot cabin there and lived in near-total isolation for most of the next twenty-four years. That cabin is where the bombs were built, and where federal agents eventually came for him.

The Bombing Campaign

The first device detonated on May 25, 1978, at a university in Chicago, injuring a campus security officer named Terry Marker.³ Over the next seventeen years, Kaczynski mailed or hand-delivered sixteen bombs, almost all targeting people connected to universities or airlines. The attacks grew more lethal over time.

Three people were killed:

Hugh Scrutton, a computer store owner, in Sacramento, California, on December 11, 1985.
Thomas J. Mosser, a public relations executive, at his home in New Jersey on December 10, 1994.
Gilbert Brent Murray, president of the California Forestry Association, at his office on April 24, 1995.³

The survivors suffered permanent injuries. John Hauser, a graduate student at UC Berkeley, lost four fingers and sustained a severed artery in 1985. Geneticist Charles Epstein lost three fingers and partial hearing in 1993. Yale computer science professor David Gelernter lost his right hand and sustained eye damage from a bomb that same year. Gary Wright suffered severe nerve damage to his left arm in a 1987 Salt Lake City attack. In 1979, twelve passengers on an American Airlines flight from Chicago to Washington suffered smoke inhalation when a bomb in the cargo hold partially detonated.⁴

Why He Was So Hard to Catch

The FBI opened a task force in 1979, joined by the Bureau of Alcohol, Tobacco and Firearms and the U.S. Postal Inspection Service. The investigation was codenamed UNABOM, short for “UNiversity and Airline BOMbing.” At its peak the task force had more than 150 full-time investigators, analysts, and support staff.⁵

Kaczynski was unusually difficult to identify. He built his devices from scrap, leaving almost no forensic trail, and chose his victims through library research rather than any personal connection. The FBI’s profile placed him near Chicago, Salt Lake City, and the San Francisco area, but investigators spent years looking for someone roughly a decade older than Kaczynski actually was, and they did not suspect a Harvard graduate and former Berkeley professor.⁶ A 1987 eyewitness sighting outside a computer store in Salt Lake City produced one of the most widely circulated FBI composite sketches in history. It did not lead to him.

The Manifesto That Exposed Him

In June 1995, the anonymous bomber sent a 35,000-word essay titled “Industrial Society and Its Future” to The Washington Post and The New York Times, threatening further attacks unless it was printed in full within ninety days.⁷ FBI Director Louis Freeh and Attorney General Janet Reno recommended publication, hoping someone would recognize the author. The Washington Post ran the manifesto as an eight-page insert in September 1995, with The New York Times covering half the printing cost. The two papers said the decision was made in the belief it could save lives.

It worked. Linda Patrik, the wife of David Kaczynski, noticed similarities between the published essay and letters David had received from his estranged older brother. David at first did not believe Ted could be the bomber, but after reading the manifesto himself, he recognized it.⁸ He gave the FBI writing samples, and linguistic analysis concluded that the manifesto and the family letters were almost certainly the work of the same person.⁵

Arrest and Evidence at the Cabin

On April 3, 1996, FBI agents arrested Kaczynski at his cabin near Lincoln, Montana. The search turned up bomb-making components, one live and mailable bomb, the original manuscript of the manifesto, and roughly 40,000 handwritten journal pages documenting bomb experiments and the crimes themselves.⁴

His attorneys, Quin Denvir and Judy Clarke, moved to suppress the evidence, arguing the search warrant was based on remarks from Kaczynski’s mother Wanda and brother David that had been misrepresented or taken out of context. On June 27, 1997, U.S. District Judge Garland E. Burrell Jr. denied the motion, finding the warrant affidavit gave a substantial basis to believe evidence of a crime would be at the cabin.⁹

The FBI later paid David Kaczynski the $1 million reward for identifying his brother. David, then a social worker in Schenectady, New York, said he would use most of it to compensate the bombing victims’ families.¹⁰

A federal grand jury in the Eastern District of California returned a ten-count indictment on June 18, 1996, charging Kaczynski in connection with four bombings. A separate New Jersey indictment covered additional attacks, bringing the total to thirteen counts.¹¹

The Fight Over a Mental Illness Defense

As trial approached, Kaczynski clashed sharply with his own lawyers. Denvir and Clarke wanted to argue he suffered from schizophrenia. Kaczynski refused to be portrayed as mentally ill. On December 22, 1997, the two sides agreed that the defense would not present expert mental health testimony during the guilt phase but could use mental health evidence for mitigation at sentencing.¹²

The agreement broke down within weeks. On January 5, 1998, Kaczynski learned his lawyers still intended to introduce non-expert evidence of his mental state during the guilt phase, including photographs of his cabin meant to illustrate his psychological condition. Three days later he asked to represent himself.¹³

Reports of a possible suicide attempt followed, and Judge Burrell ordered a competency evaluation. Forensic psychiatrist Dr. Sally Johnson interviewed Kaczynski for about nineteen hours over roughly a week. She concluded he was competent to stand trial and able to assist his attorneys despite a psychiatric diagnosis. Her full report, later unsealed, diagnosed him with paranoid schizophrenia along with a premorbid paranoid personality disorder with avoidant and antisocial features, citing delusional beliefs about being controlled by modern technology.¹⁴

On January 22, 1998, Judge Burrell denied the self-representation request as untimely, finding the jury had already been empaneled and that the motion was a tactical attempt to delay the trial.¹²

Guilty Plea and Sentencing

Immediately after Judge Burrell denied his request to serve as his own lawyer, Kaczynski entered an unconditional guilty plea to all counts in both the California and New Jersey indictments. The government withdrew its notices of intent to seek the death penalty. Kaczynski waived his trial and appellate rights.¹²

On May 4, 1998, Judge Burrell sentenced him to four consecutive life terms without parole plus thirty years and ordered more than $15 million in restitution.¹⁵ Victim impact statements dominated the hearing. Susan Mosser, widow of Thomas Mosser, asked the judge to “make this sentence bulletproof, bombproof” and to “lock him so far down that when he does die, he’ll be closer to hell.” Charles Epstein criticized Kaczynski for pleading guilty to spare his own life. Gilbert Murray’s family stood and walked out as Kaczynski began to speak.¹⁶ Judge Burrell said Kaczynski had committed “unspeakable and monstrous crimes for which he shows utterly no remorse.”¹⁷

The Appeal

Although the plea agreement waived direct appeal, Kaczynski filed a motion under 28 U.S.C. § 2255 on April 23, 1999, to vacate his conviction. He argued that his plea was involuntary because his lawyers insisted on a mental status defense over his objection and because the court had wrongly denied his self-representation request. The district court denied the motion without a hearing. On February 12, 2001, the U.S. Court of Appeals for the Ninth Circuit affirmed, finding the plea voluntary and the self-representation denial proper as an untimely tactical maneuver.¹²

Death in Prison

Kaczynski was found unresponsive in his cell at the Federal Medical Center in Butner, North Carolina, at about 12:30 a.m. on June 10, 2023. Responders performed CPR and briefly revived him before he was taken to a hospital and pronounced dead. He was eighty-one.¹ An autopsy confirmed the cause of death as hanging. He had been diagnosed with rectal cancer in March 2021 and was reportedly depressed in the period before his death.¹⁸

He never reconciled with the brother who turned him in. After his arrest, Ted refused to put David on his visitors list and responded to a letter from him with hostility, writing: “You will go to hell because, for you, seeing yourself as you really are will truly be hell.”¹⁹
