The state of Ohio is trying to take away the registered nurse's license of Donna Moonda, whose husband was shot to death along the Ohio Turnpike last year.

She has until June 21 to request a hearing challenging the board of nursing's plan to suspend or revoke her license.

The board's case against Ms. Moonda centers on her stealing the painkiller fentanyl from UPMC Horizon in Mercer County, Pa. She pleaded no contest in 2004 to smuggling the drug out of the hospital and using it to feed her addiction. Pennsylvania suspended her nursing license last fall because of the thefts.

After police and the hospital staff caught her, Ms. Moonda, 47, went through a drug rehabilitation program in Beaver County. There she met and began a sexual relationship with Damian Bradford, 24, who is charged in the shooting death of Ms. Moonda's husband, Dr. Gulam Moonda.

A robber killed Dr. Moonda, 69, on May 13, 2005, while he was traveling with his wife and mother-in-law on the Ohio Turnpike. Donna Moonda told police she could not identify the killer, though federal prosecutors allege it was her boyfriend.

They will not discuss whether Ms. Moonda is a suspect in her husband's slaying but say their investigation is ongoing.

Ohio's nursing board began its case against Ms. Moonda after Pennsylvania suspended her license.

Ms. Moonda, of Hermitage, worked as a nurse anesthetist until hospital supervisors in Mercer County discovered that her requisitions of fentanyl were unusually high.

Police records say UPMC Horizon reviewed 60 surgical cases involving Ms. Moonda and other nurse anesthetists. Ms. Moonda's allocations of the drug "generally far exceeded that of other practitioners," according to Lawrence Fuksa, a narcotics agent for the Pennsylvania attorney general.

Ms. Moonda later admitted to the hospital staff that she was stealing fentanyl for herself.

She received three years' probation after her conviction and is in good standing with the Pennsylvania Board of Probation and Parole.
