(CNN)A 36-year-old nurse has been arrested on suspicion of impregnating a woman in a vegetative state who unexpectedly gave birth last month at a Phoenix health care facility, police said Wednesday. A court order compelled Sutherland to provide a DNA sample to investigators on Tuesday, and crime lab technicians determined his DNA “matched the baby,” Phoenix police Sgt. Tommy Thompson said. Sutherland was arrested on Tuesday. A judge set a cash bond at $500,000 and scheduled Sutherland’s next court appearance for January 30. The nurse is being held in the Maricopa County Jail.
