In 2002, a dead newborn baby boy was discovered at a recycling plant in Storm Lake, Iowa. Police could neither identify him nor determine the cause of death, so they turned to local doctors and nurses to try to find his mother. When they subpoenaed the records of women who’d had pregnancy tests at the local Planned Parenthood, however, the clinic fought the order to the Iowa Supreme Court, which ultimately stayed it. “For many women, it’s the most personal test they’ve ever had done,” then–clinic manager Susan Thayer was quoted saying in USA Today. “They come in expecting the information will stay here.”
