Gregory Davis, 17, is in jail, charged with raping the women who lived in the Chatham Creek Rest Home and Retirement Center. The woman died 10 days later.
Police said Davis admits he raped the woman.
Wake County inspectors issued a report after visiting the rest home four times. The report listed several safety violations: lighting was not working, a door lock was broken, and the woman was isolated. The report said the rest home failed to protect the victim from abuse, calling her "easy prey."
One inspector told WRAL that the state Department of Facilities and Services called the report "weak" and asked the county to withdraw it. A spokeswoman for the state denied the claims, saying her department had several questions about the report and gave the county options to address them.
The spokeswoman said the report pointed out deficiencies at the rest home, but the deficiencies did not lead to the rape.
The county said it stands by its report. The inspector said the county will not rework the report, hoping to change the state's opinion.
The victim's son told WRAL he wants to speak to county officials before he comments about the report.
Cary investigators are waiting on autopsy results to see if the rape caused the victim's death. That could determine whether Gregory Davis will be charged with murder.
