Investigators say the woman was walking alone in an alley Tuesday afternoon when she was confronted by a man resembling the sketch. He implied that he had a gun in his pocket and tried to get her to a more secluded area.
They struggled and the woman ran away. She was hit twice in the face.
The suspect was unshaven and had a spider web tattoo on the left side of his neck.
Anyone with information should call Crystal Lake police.
