A judge clears the way for New Jersey's worst serial killer to donate a kidney.
If Charles Cullen and his doctors meet certain conditions, he may undergo an operation to remove one of his kidneys.
The Associated Press reports the organ would then go to the relative of a friend.
Cullen admitted to killing 29 patients in nursing homes and hospitals throughout Pennsylvania and New Jersey.
Prosecutors agreed to spare him from the death penalty if he identified patients who had been given lethal drug overdoses.
The judge ordered that the operation must be paid for by the recipient's insurance company. The state's medical examiners must also certify the doctors prior to the procedure.
