An autopsy found a level of morphine in the baby's body that a pathologist testified could have been lethal for an adult.
With no needle marks on the child's body, authorities decided the drugs must have gotten into the infant through her mother's milk, prosecutor Barry Barnette said.
A review of her medical records showed Greene carefully hid her pregnancy from her primary doctor.
After a home pregnancy test showed she was pregnant, she told her primary doctor she needed to go to a gynecologist for a birth control.
She then got prenatal care from that doctor while not telling her all the painkillers she was taking.
She also skipped appointments with her primary physician when it was obvious she was pregnant and sent her husband to pick up her painkiller prescriptions, Barnette said.
“She was a nurse. She knew how to work the system,” Barnette said. “She caused the loss of that child.”
Greene spent more than 10 years racked with chronic pain after a car wreck before her unexpected pregnancy with her husband in 2010, attorney Rauch Wise said.
