There may be new information on the 1982 Tylenol-related deaths that led to the introduction of the now-standard tamperproof packaging. Federal agents searched the home of James W. Lewis, who is linked to the fatal poisonings and the FBI in Chicago said authorities are reviewing evidence in the deaths, citing “advances in forensic technology.” Lewis served more than 12 years in prison for sending an extortion note to Johnson & Johnson demanding $1 million to "stop the killing." He also served two years out of a 10-year sentence for tax fraud and was later charged with rape and kidnapping. No one has been charged yet in the current investigation.
