Chicago Tylenol murders

The Chicago Tylenol murders occurred when seven people died after taking pain-relief medicine capsules that had been poisoned. The poisonings, code-named TYMURS by the Federal Bureau of Investigation, took place in late 1982 in the Chicago area of the United States.
These poisonings involved Extra-Strength Tylenol capsules, manufactured by McNeil Consumer Healthcare, which had been laced with potassium cyanide. The incidents led to reforms in the packaging of over-the-counter substances and to federal anti-tampering laws. The case remains unsolved and no suspects have been charged. A $100,000 reward, offered by Johnson & Johnson, McNeil's parent company, for the capture and conviction of the "Tylenol Killer", has never been claimed.

The incidents

On the morning of September 29, 1982, twelve-year-old Mary Kellerman of Elk Grove Village, Illinois, died after taking a capsule of Extra-Strength Tylenol. Adam Janus of Arlington Heights, Illinois, died in the hospital shortly thereafter. Adam's brother Stanley of Lisle, Illinois, and sister-in-law Theresa died after gathering to mourn his death, having taken pills from the same bottle. Soon afterward, Mary McFarland of Elmhurst, Illinois, Paula Prince of Chicago, and Mary Reiner of Winfield, also died in similar incidents. Investigators soon discovered the Tylenol link. Urgent warnings were broadcast, and police drove through Chicago neighborhoods issuing warnings over loudspeakers.
As the tampered-with bottles came from different factories, and the seven deaths had all occurred in the Chicago area, the possibility of sabotage during production was ruled out. Instead, the culprit was believed to have entered various supermarkets and drug stores over a period of weeks, removed packages of Tylenol from the shelves, adulterated their contents with solid cyanide compound at another location, and then replaced the bottles. In addition to the five bottles which led to the victims' deaths, three other tampered with bottles were discovered.
Johnson & Johnson distributed warnings to hospitals and distributors and halted Tylenol production and advertising. On October 5, 1982, it issued a nationwide recall of Tylenol products; an estimated 31 million bottles were in circulation, with a retail value of over US$100 million. The company also advertised in the national media for individuals not to consume any products that contained acetaminophen. When it was determined that only capsules were tampered with, they offered to exchange all Tylenol capsules already purchased by the public with solid tablets.

Suspects

During the initial investigations, a man named James W. Lewis sent a letter to Johnson & Johnson demanding $1 million to stop the cyanide-induced murders. Police were unable to link him with the crimes, as he and his wife were living in New York City at the time. He was convicted of extortion, served thirteen years of a twenty-year sentence, and was released in 1995 on parole. WCVB Channel 5 of Boston reported that court documents, released in early 2009, "show Department of Justice investigators concluded suspect James W. Lewis, who now lives in Cambridge, Massachusetts, was responsible for the poisonings, despite the fact that they did not have enough evidence to charge him." Lewis continues to deny responsibility for the poisonings.
A second man, Roger Arnold, was investigated and cleared of the killings. He had a nervous breakdown due to the media attention, which he blamed on Marty Sinclair, a bar owner. In the summer of 1983, Arnold shot and killed John Stanisha, whom he mistook for Sinclair. Stanisha was an innocent man who did not know Arnold. Arnold was convicted in January 1984 and served fifteen years of a thirty-year sentence for second-degree murder. He died in June 2008.
Laurie Dann, who poisoned and shot victims in a May 1988 rampage in and around Winnetka, Illinois, was briefly considered as a suspect, but no direct connection was found.
On May 19, 2011, the FBI requested DNA samples from Ted Kaczynski, known as the "Unabomber", as part of its investigation into the killings.

Aftermath

The media gave Johnson & Johnson much positive coverage for its handling of the crisis; for example, an article in The Washington Post said, "Johnson & Johnson has effectively demonstrated how a major business ought to handle a disaster." The article further stated that "this is no Three Mile Island accident in which the company's response did more damage than the original incident," and applauded the company for being honest with the public. In addition to issuing the recall, the company established relations with the Chicago Police Department, the FBI, and the Food and Drug Administration. This way it could have a part in searching for the person who laced the capsules and they could help prevent further tamperings. While at the time of the scare the company's market share collapsed from thirty-five percent to eight percent, it rebounded in less than a year, a move credited to the company's prompt and aggressive reaction. In November, it reintroduced capsules but in a new, triple-sealed package, coupled with heavy price promotions and within several years, Tylenol had become the most popular over-the-counter analgesic in the U.S.
A number of copycat attacks involving Tylenol and other products ensued during the following years. One of these incidents occurred in the Chicago area; unlike Tylenol, it actually forced the end of the product affected by the hoax, Encaprin, from Procter & Gamble. The incident inspired the pharmaceutical, food, and consumer product industries to develop tamper-resistant packaging, such as induction seals and improved quality control methods. Moreover, product tampering was made a federal crime.
Additionally, the tragedy prompted the pharmaceutical industry to move away from capsules, which were easy to contaminate as a foreign substance could be placed inside without obvious signs of tampering. Within the year, the FDA introduced more stringent regulations to avoid product tampering. This led to the eventual replacement of the capsule with the solid "caplet", a tablet made in the shape of a capsule, as a drug delivery form and with the addition of tamper-evident safety-seals to bottles of many sorts.

Ongoing investigations

In early January 2009, Illinois authorities renewed the investigation. Federal agents searched the home of Lewis in Cambridge, Massachusetts, and seized a number of items. In Chicago, an FBI spokesman declined to comment but said "we'll have something to release later possibly." Law enforcement officials have received a number of tips related to the case coinciding with its anniversary. In a written statement, the FBI explained,

This review was prompted, in part, by the recent 25th anniversary of this crime and the resulting publicity. Further, given the many recent advances in forensic technology, it was only natural that a second look be taken at the case and recovered evidence.

In January 2010, both Lewis and his wife submitted DNA samples and fingerprints to authorities. Lewis stated "if the FBI plays it fair, I have nothing to worry about."
On May 19, 2011, the FBI requested DNA samples from 'Unabomber' Ted Kaczynski in connection to the Tylenol murders. Kaczynski denied having ever possessed potassium cyanide. The investigation is still under way. The first four Unabomber crimes happened in Chicago and its suburbs from 1978 to 1980, and Kaczynski's parents had a suburban Chicago home in Lombard, Illinois in 1982, where he stayed occasionally.
