it was the usher ghost that growled at the police officer on the camera
He was Richard Duffin a usher at the Capitol Theater. He died when a fire started in the theater. He ran back in but could not get out as the theater collapsed on to him. Now he is a shadow of his former self: playing music, opening doors and leaving the smell of smoke. This spirit may have died in pain, agony and angry for the lack of help.
