--> }} The Chicago Tylenol murders were a series of poisoning deaths resulting from drug tampering in the Chicago metropolitan area in 1982. The victims had all taken Tylenol-branded acetaminophen capsules that had been laced with potassium cyanide. James William Lewis was convicted of extortion for sending a letter taking credit for the deaths and demanding $1 million to stop them, and he was also the primary suspect in the killings despite living in New York City at the time. The incidents led to reforms in the packaging of over-the-counter substances and to federal anti-tampering laws. ==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 later that day. Shortly thereafter Adam's brother Stanley and sister-in-law Theresa, of Lisle, Illinois, died after gathering to mourn his death, having taken pills from the same bottle.〔http://www.pbs.org/newshour/updates/tylenol-murders-1982/〕 In the coming days Mary McFarland of Elmhurst, Illinois, Paula Prince of Chicago, and Mary Reiner of Winfield also died in similar incidents.〔Douglas, 106.〕〔 〕 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 acquired bottles of Tylenol from various supermarkets and drug stores over a period of several weeks, added the cyanide to the capsules, then returned to the stores to place the bottles back on the shelves. In addition to the five bottles that 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.〔Emsley, John. ''Molecules of Murder: Criminal Molecular and Classic Cases.'' Cambridge:Royal Society of Chemistry, 2008, p. 174.〕 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 for solid tablets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chicago Tylenol murders」の詳細全文を読む スポンサード リンク
