I think the point of this character as many others in this novel was to cast a whole small-town community. After all, you could just as easily asked what is the point of characters like Shirley,the Boddin parents, Harriet and Lester Durham and numerous others. I believe it was done for style and atmosphere and Mr. King said once that he did it in two occasions - Salem's Lot and The Stand (two of my favorites actually). You can find a complete list of this book characters at
