The outside of the Kentucky Children's Hospital is all colorful paintings and smiling photos, but inside there's a dark secret. Connor Wilson was the first to die, on August 30, at six months old. His parents, while heartbroken, didn't think anything was amiss until another baby in the same ward, Rayshawn Lewis-Smith, died. Then they found out Waylon Rainey, also on the cardiac surgery floor, coded and was on life support and a fourth baby, Jaxon Russell needed a second surgery at another hospital to fix a heart surgery he'd had a Kentucky Children's. All of these events happened within eight weeks, after which the hospital closed its cardiac surgery program and placed its chief surgeon on leave. When the parents asked the hospital questions, the hospital wouldn't answer them. When a local reporter started asking questions, the hospital sued her. When the state Attorney General asked these same basic questions - how many pediatric heart surgeries they did, their mortality rates - the hospital refused to hand over the data. When the AG ruled they were in violation of state law by not releasing their data, the hospital appealed the ruling. Now the hospital says they plan to re-open their pediatric cardiac surgery program, and these parents are up in arms. How could the hospital possibly open back up with this kind of track record, without even releasing the most basic safety data, which many other hospitals release all the time? And why haven't state or federal regulators rushed in to stop the program from re-opening - they haven't even opened an investigation. Elizabeth Cohen investigates.
