We have to believe that after the description given by the three teenagers of a white male adult, within seconds the dispatcher had incorrectly relayed a new description of a black male. It has been said that maybe the dispatcher misheard the teenagers or they were speaking quickly or frantically, but this is unlikely. When a dispatcher has a frantic or erratic call, they are often told to tell the person on the phone to take a deep breath and slow down or if they didn't hear the person properly, to ask them to repeat the information. But somewhere here, the error still occurred from this anonymous dispatcher. But that is not all.
The teenagers rang in and described the suspect as a "white male, 5'8" in height, rimmed glasses, dark clothing, heavy build, reddish-blond hair and a crew cut." See here and view police report: http://www.zodiackiller.com/Stine.html. Well the next logical step is for the dispatcher to pass this description in its entirety onto the police. It would make no sense to ignore the whole description and just pass on the part about a black male. So if we take the claims at face value, the dispatcher incorrectly changed white male to black male. The description the dispatcher sent out should therefore have read "black male, 5'8" in height, rimmed glasses, dark clothing, heavy build, reddish-blond hair and a crew cut." and supposedly this made sense and was never questioned immediately. The late 1960's sported many hair cuts, but a black male with a reddish-blond crew cut sounds out of the ordinary, unless we are to believe only the color part of the description was relayed.
Now let us accept the widely held view that the description the police received was that of a "black male, 5'8" in height, rimmed glasses, dark clothing, heavy build, reddish-blond hair and a crew cut." As Donald Fouke passes the suspect on Jackson Street he notices it's a white male, but hang on, the entire rest of the description fits, down to the crew cut, glasses, clothing, weight and height, only the color of his skin is wrong. Surely this man was still worthy of questioning and I believe that's exactly what happened, he was questioned, except the premise that he was a black man, who never really existed in the first place.
