A psychologist who illegally prescribed oxycodone to one of his patients is being sued by her family following her death by an overdose of the painkiller, according to the Sun-Sentinel. The psychologist, who was not legally allowed to write prescriptions, used prescription pads stolen from physicians. The Sun-Sentinel reports that the clinic where the psychologist worked is also a defendant in the lawsuit, which seeks unspecified damages. The psychologist, who was dating the 20-year-old woman, has been charged with manslaughter.
