Siren sound

Is it possible the siren sound came from a supercharger? Shelby and Ford have a close relationship going back years. Shelby offers a supercharged version of the SVT Raptor ( with 575hp. There are also various other aftermarket superchargers available. Depending on the drive system a supercharger can make a distinctive whirring sound that rises and falls in frequency with the engine RPM.
