The care facility in Arizona where an incapacitated woman was raped and later gave birth will soon be closed, the nursing home’s operator announced on Thursday.

In a statement, the operator, Hacienda HealthCare, said it was working to determine exactly how it would move its patients from the Phoenix facility elsewhere and did not specify a location. It pledged to do “everything in our power” to ensure that the transition would be smooth.

A spokesman for the company said 37 patients would be affected.

“The Hacienda Healthcare board of directors, after a great deal of careful consideration, has come to understand that it is simply not sustainable to continue to operate our Intermediate Care Facility for the Intellectually Disabled,” the company’s statement said, adding that the board had voted on Feb. 1 to close the nursing center.

State agencies were notified of the board vote the same day.

Some state officials, though, reacted Thursday with surprise. They said that when they met with Hacienda officials on Monday, the company acknowledged the board’s vote, but did not provide notice to terminate its contract or provide a transition plan as required by its contract with the state. As recently as Thursday, state officials added, discussions about how to maintain patient care at the center were continuing.
