Police in Phoenix are investigating a possible sexual assault after a cognitively-impaired woman gave birth to a baby at a care facility on Saturday.

The woman has been a patient at the Hacienda HealthCare Skilled Nursing Facility for over 20 years, her lawyer says. Her baby is healthy.

A source told Arizona's Family that workers didn't know she was pregnant until she went into labor.

Police in Phoenix are investigating a possible sexual assault after a cognitively-impaired woman gave birth at a healthcare facility on Saturday.

The unnamed woman has been a patient at the Hacienda HealthCare Skilled Nursing Facility for over 20 years, her lawyer told INSIDER, after seizures as a child left her with significant intellectual disabilities.

A source familiar with what happened, who asked to remain anonymous, told Arizona's Family that staffers at the facility had no idea the woman was pregnant until she went into labor on Saturday.

"From what I've been told, she was moaning," the source said. "And they didn't know what was wrong with her."

The source said a nurse at the facility delivered the baby, who is "alive" and "healthy."

Law enforcement immediately got involved to determine how the pregnancy could have happened.

The source said the patient required around-the-clock care and that many people would have had access to her room. Since the birth, the facility has instituted a new rule, requiring male staffers to be escorted by a female staffer whenever they go into a room with a female patient, according to Arizona's Family.

INSIDER found that the nursing facility had been previously cited by state health authorities for another complaint of inappropriate behavior. A nursing assistant and resident complained to inspectors that nurses would enter shower rooms while residents were bathing naked, which made some feel uncomfortable.

A spokesperson for Hacienda HealthCare, which cares for about 2,500 people in Arizona, released a statement to Arizona's Family saying that they could not comment on patients or the investigation but that "our patients' and clients' health and safety is our #1 priority."

Arizona's Family reported that the Arizona Department of Economic Security also released a statement, saying they had "immediately dispatched a team to conduct health and safety checks" on all of the residents, and Phoenix Police Sgt. Tommy Thompson confirmed that the matter was under investigation.

Editor's Note: This story has been updated to clarify the woman is more cognizant than was initially reported. The family's attorney told INSIDER on January 22 that she is cognitively impaired and has significant intellectual disabilities, but she can make some movements and facial gestures.
