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 September and early October 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.
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 after. Adam's brother Stanley of Lisle, Illinois, and wife 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, Johnson & Johnson offered to exchange all Tylenol capsules already purchased by the public with solid tablets.
During the initial investigations, a man named James William 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 13 years of a 20-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 Lewis was responsible for the poisonings, despite the fact that they did not have enough evidence to charge him." Lewis has denied responsibility for the poisonings for several years.
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 15 years of a 30-year sentence for second-degree murder. He died in June 2008.
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 (see Stella Nickell for information on the 1986 Excedrin tampering murders) ensued during the following years. One of these incidents occurred in the Chicago area and, although a hoax, it actually forced the end of the product affected, Encaprin, fromProcter & 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.
