Police know there's a serial rapist in a particular area. He's left no DNA and victims never saw his face. Police learn that a unknown female victim from that area was examined by a sexual assault forensic examiner and a rape kit was secured. However the victim chose the option of not immediately reporting the rape so the kit is held until the victim signs the release (if she does) what can police do to find the victim considering HIPAA and state laws protecting her identity?
It is important to note that the Health Insurance Portability and Accountability Act (HIPAA) is a federal law that protects the privacy of an individual's medical information. It does not prevent the police from obtaining evidence in a criminal investigation, but it does place certain restrictions on how that information can be used and disclosed.
In the scenario you have described, it is possible that the police could request a court order or subpoena to obtain the rape kit and any other relevant medical information related to the victim's examination. This would typically require the police to show that they have probable cause to believe that the evidence is relevant to the investigation and that they have exhausted all other reasonable means of obtaining it.
It is also possible that state laws or local policies may place additional restrictions on the police's ability to obtain this information.
