Meantime, other facts came to light in connection with the mystery. The ill-fated sloop had run into the schooner “John B. Mathew,” Captain Nickerson, early on Wednesday morning, at which time only one man was seen on board, and this man was subsequently observed to lower the boat from the stern, and leave the sloop. This collision took place just off Staten Island, and was so severe as to render the “John B. Mathew” unfit for sea. Hence, she returned to the city for repairs. On the same afternoon that the officers started after Johnson, officers Burdett and James, accompanied by our reporter, set out in search of the yawl belonging to the sloop, which was said to be adrift off Staten Island. This they succeeded in finding, and bringing to the city, after a tedious passage on a rough sea with a cold wind. The boat contained two oars, a right boot, a tiller, and part of an old broom. George Neidlinger, the hostler at Fort Richmond, south of which the boat was found, said that shortly before six o’clock the previous morning, he had seen a man land from the boat, whom he described in such a manner as to show that Johnson might be the individual. It was next ascertained that a man answering the same description had made himself conspicuous at the Vanderbilt landing, where he had indulged freely in oysters, hot gins, and eggs. He was seen on the seven o’clock boat coming up to New York, by a deck hand, who had, by his own solicitation, counted a portion of his money, which he carried in two small bags, like shot-bags. Here the matter rested for a short time, while the people were waiting for news from the officers at Providence. It was during this interval that our artist succeeded in procuring the sketches herewith presented. Meantime the sloop lying at the Fulton Market Slip was attended, day after day, by multitudes of the curious and the excited. The story of blood was the topic of conversation, and the spirit of revenge found a limited relief in verbal expressions of bitter desire for the punishment of the perpetrator, if he should be arrested. Mr. Selah Howell, of Islip, L. I., part owner of the sloop, was on hand. He suspected William Johnson, the man who took supper with Captain Burr and himself in the cabin, on the evening before the sloop left the city. The theory that the murder had been committed by one of the crew favored this suspicion, and the idea floated from ear to ear until it became a settled conclusion in every mind. Mr. Howell viewed the boat, and identified it as belonging to the sloop. The carman, who conveyed Johnson’s baggage to the Fall River steamboat, also described the man who had employed him, and the woman who was with him.
