Sandra Joyner, 45, thought a little cosmetic surgery was just the thing to help refresh her looks. What she didn’t know was that her plastic surgeon’s nurse anesthetist was a former high school classmate looking for revenge.

Joyner died five years ago when she went into respiratory arrest in the recovery room at her plastic surgeon’s office. She was taken to a hospital where, several days later, she was removed from life support.

In 2003, after an investigation, the medical board called Sally Jordan Hill “grossly negligent” for injecting Joyner with a powerful painkiller without doctor’s orders and waiting too long before alerting anyone that Joyner was having problems. It was a medical error.

Last month, that error was amended to murder when Hill, 50, was charged with first-degree murder for poisoning Joyner with fentanyl and turning off the alarm that would have alerted other personnel to Joyner’s condition. Hill believed Joyner had stolen her high school boyfriend when they both attended the same school in the early 1970s.
