正好在查显窃启方面的东西，顺手找到这个：

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.[1] 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.

82年的芝加哥，强生制造的泰诺被人下毒-氰化钾，一个12岁的孩子因此死亡。
强生为此悬赏10万美元，至今杀手未被抓获。

结果强生召回了全美所有的泰诺，损失上亿美元
