In People v. Mangiefico (1972) 25 Cal.App.3d 1041, the court stated, "In determining whether a private investigator should be required to give the Miranda warning the inquiry is directed to whether the investigator is acting as an agent of law enforcement officials or is primarily engaged in enforcing the law. If he is, then Miranda comes into play. We have already concluded that Berdan was not an agent of the local law enforcement officers and that he was not primarily engaged in law enforcement."
