A South Carolina woman has been charged with unlawful conduct towards a child after a diabetic teen in her care drank a milkshake and then died, officials say. 50-year-old Shirl Lee Sweeney allegedly let a 17-year-old girl in her care drink a milkshake, knowing the teen was diabetic and that the drink would have adverse consequences on her health. Following the consumption of the milkshake, the teen began vomiting, but was not taken to the hospital until the next day, when Sweeney found her on the bathroom floor.
