A few days passed away, when, one morning about three o'clock, as some members of the city patrol were passing through Church Street, they discovered a man, apparently n a dying state, lying in the street. He was conveyed to the guard house, or patrol station, where he died in the course of half an hour, without being able to articulate a syllable. Several wounds in different parts of his body, made by a small penknife, which was subsequently found, were undoubtedly the cause of his death. The unfortunate man thus murdered was the captain of the slaver, who had sought to entrap me by his honeyed words. A pool of blood was on the spot on which he was first discovered, and his steps could be traced by the blood on the pavements for several rods. The marks of blood were found only in the middle of the street; and none of the persons residing in that part of the city heard any disturbance, brawl, or cries for assistance in the course of the night. The mysterious tragedy caused a great excitement. The police were unceasing in their efforts to discover the circumstances connected with this assassination, but in vain. The veil which concealed it was not lifted, and no clew was ever given by which even conjecture could develop the mystery. It was supposed by some that the unfortunate man fell a victim to the rage of a jealous husband whose honor he had outraged, or of a lover whose affections he had supplanted. Others thought the fatal injuries he received were the result of a drunken quarrel, commenced in a gaming house; while many believed that private revenge inflicted the stabs, which, from their number and direction, appeared to have been given under the influence of ungovernable fury. Some thought the wounds were inflicted by a vigorous man, others, that a woman had imbrued her hands in his blood.
