PHOENIX –  A nurse facing criminal charges in the rape of an incapacitated woman who later gave birth at a long-term care facility in Phoenix pleaded not guilty Tuesday during a brief court appearance.

The only comments by Nathan Dorceus Sutherland came when he identified himself to the court and stated his birth date. Afterward, Sutherland’s attorney declare a intense defense, but declined to answer questions from reporters.

Authorities say Sutherland, 36, was working at a licensed practical nurse at Hacienda Healthcare in Phoenix when he raped the 29-year-old victim, who has been in long-term care since age 3 after suffering a near-drowning.

She gave birth to a boy at the facility on Dec. 29. Employees said they had no idea she was pregnant.

The surprise birth setoff reviews by state agencies, highlighted safety concerns for patients who are severely disabled or incapacitated and prompted the resignations of Hacienda’s chief executive and one of the victim’s doctors.

Investigators say Sutherland’s DNA matched a sample from the woman’s newborn boy, who is being cared for by her family.

Sutherland, who was hold and carrying a legal pad during the arraignment hearing, pleaded not guilty to charges of sexual abuse and abuse of a vulnerable adult. He remains jailed on a $500,000 bond.
