Most (credible) people think that Lee Harvey Oswald was being run by U.S. intelligence – probably both CIA and the Office of Naval Intelligence (because the Marines are part of the Navy) as well as being an FBI informer.
Oswald tried to call Raleigh – but that phone call was not allowed to go through!! Meaning the authorities did not want Oswald to contact his intelligence handler through a cut-out.
This is an excellent presentation on that by Dr. Grover Proctor.
Oswald tried to call 919-834-7430 for John Hurt. It was a landline number that is now disconnected and was registered to Billie G. Hurt fo 513 E. Whitaker Mill Road, Raleigh, NC 27608 at last glance on the internet White Pages: https://www.whitepages.com/phone/1-919-834-7430
Lee Harvey Oswald was NOT allowed by the authorities to call John Hurt of Raleigh, NC- That is because it had something to do with Oswald’s counterintelligence work with the U.S. government.
