Hill was an certified nurse anesthetist who treated Joyner when she underwent a mini-face-lift by Dr. Peter Tucker at the Center for Cosmetic and Plastic Surgery in Charlotte. Joyner's death after being monitored by Hill in a recovery room originally had been ruled an accident. Hill has said she gave Joyner fentanyl, a painkiller that authorities said caused the patient to go into respiratory arrest.

But Hill and Tucker were named in a malpractice lawsuit filed by the Joyner family that was settled in 2003. The N.C. Medical Board, which investigated Joyner's death, said Hill didn't alert the doctor to Joyner's condition and performed medical acts without a licensed physician's supervision.

Sources said Joyner and Hill knew each other while in high school in the 1970s but did not get along. On Sunday, though, several former Olympic students who were at the southwest Charlotte high school at the same time as Hill and Joyner said they didn't know the two knew each other.

Byrum met Joyner through her then-boyfriend and current husband, Robby Byrum. The group stayed friendly over the years, including while enrolled at Western Carolina University.

"She was real bubbly and likeable," said Joye Byrum, who was a cheerleader with Joyner. Joyner also could be very headstrong and strong-willed, she said.

At Hill's two-story home in the Wedgewood subdivision in western Union County, a flag with the words "Welcome Ewe" and an image of a sheep hung near the garage Sunday afternoon, and a dark gray Chrysler Grand Caravan was parked in the driveway.

A neighbor said that Hill has lived in the house for more than a decade and that he was surprised at the murder charge. Because Hill lives alone, the neighbor said, he is feeding her cats while she's in jail.

Neither Don Newman, the principal of Olympic High School when the women attended, nor Charlotte-Mecklenburg School Board Chairman Joe White, the athletic director at that time, recalled Joyner or Hill.

An Olympic yearbook showed that Joyner was on the cheerleading squad for three years, serving as head cheerleader while a sophomore and a junior. She also was a member of the student council, the interclub council and the pep club. The yearbook did not appear to show Hill as a member of any clubs.

While at Olympic, Sandra Baker began dating a wrestler, John Joyner. His mother, Georgia Joyner, recalled Sunday how when she and her family heard of his new girlfriend, they hurried to his yearbook to look her up.
