Vain would be all attempts to convey the horror which thrilled the gathering spectators of this piteous tragedy. It was known to the crowd that one person had, by some accident, escaped the general massacre: but she was now speechless, and probably delirious; so that, in compassion for her pitiable situation, one female neighbor had carried her away, and put her to bed. Hence it had happened, for a longer space of time than could else have been possible, that no person present was sufficiently acquainted with the Marrs to be aware of the little infant; for the bold pawnbroker had gone off to make a communication to the coroner; and another neighbor to lodge some evidence which he thought urgent at a neighboring police-office. Suddenly some person appeared amongst the crowd who was aware that the murdered parents had a young infant; this would be found either below-stairs, or in one of the bedrooms above. Immediately a stream of people poured down into the kitchen, where at once they saw the cradle--but with the bedclothes in a state of indescribable confusion. On disentangling these, pools of blood became visible; and the next ominous sign was, that the hood of the cradle had been smashed to pieces. It became evident that the wretch had found himself doubly embarrassed-- first, by the arched hood at the head of the cradle, which, accordingly, he had beat into a ruin with his mallet, and secondly, by the gathering of the blankets and pillows about the baby's head. The free play of his blows had thus been baffled. And he had therefore finished the scene by applying his razor to the throat of the little innocent; after which, with no apparent purpose, as though he had become confused by the spectacle of his own atrocities, he had busied himself in piling the clothes elaborately over the child's corpse. This incident undeniably gave the character of a vindictive proceeding to the whole affair, and so far confirmed the current rumor that the quarrel between Williams and Marr had originated in rivalship. One writer, indeed, alleged that the murderer might have found it necessary for his own safety to extinguish the crying of the child; but it was justly replied, that a child only eight months old could not have cried under any sense of the tragedy proceeding, but simply in its ordinary way for the absence of its mother; and such a cry, even if audible at all out of the house, must have been precisely what the neighbors were hearing constantly, so that it could have drawn no special attention, nor suggested any reasonable alarm to the murderer. No one incident, indeed, throughout the whole tissue of atrocities, so much envenomed the popular fury against the unknown ruffian, as this useless butchery of the infant.
