SummaryNo one disputes that Joseph Wesbecker, in a mad rampage, killed eight of his co-workers. The disagreement came over the cause of his rage. In this landmark case, the plaintiffs charged that Wesbecker's use of Prozac, a relatively new anti-depressant drug, was to blame and sued its manufacturer. The finding of the jury would have an enormous impact on this widely prescribed medication that some claimed could cause suicidal and violent outbursts.
