Medicis Pharmaceutical Corp. (MRX) shares are down 4.9% to $38.10 after reports that a woman was found dead at Chief Executive Jonah Shacknai’s California home. Officials from the Scottsdale, Ariz., specialty pharmaceutical company weren’t immediately available for comment. According to numerous media reports, the woman--identified as Shacknai’s girlfriend--was found in the courtyard of Shacknai’s Coronado, Calif., mansion on Wednesday. The Arizona Republic newspaper reported that the incident occurred after Shacknai’s 6-year old son was hospitalized earlier this week after a fall at the house. The newspaper said local police described the woman’s death as occurring under “suspicious circumstances.”
