A federal judge John F. Keenan declared a mistrial in a case investigating whether Merck & Co.'s osteoporosis drug called Fosamax causes severe dental and jaw problems. Why? Well, the AP reports, "Deliberations deteriorated to the point that lawyers waiting in the courtroom could hear screaming coming from the jury room and one female juror said another juror threw a chair at her." The trial had been going on for a month in Manhattan and the higher-ups of the drug industry as well as liability lawyers have been keeping a watchful eye on the trial, as it's the first of nearly 900 state and federal cases against the company.
