But, fortunately, there is one fact disclosed in their testimony that settles the question. Balch says, that on the evening, whenever it was, he saw the prisoner; the prisoner told him he was going out of town on horseback, for a distance of about twenty minutes' drive, and that he was going to get a horse at Osborn's. This was about seven o'clock. At about nine, Balch says he saw the prisoner again, and was then told by him that he had had his ride, and had returned. Now it appears by Osborn's books, that the prisoner had a saddle-horse from his stable, not on Tuesday evening, the night of the murder, but on the Saturday evening previous. This fixes the time about which these young men testify, and is a complete answer and refutation of the attempted alibi on Tuesday evening.
I come now to speak of the testimony adduced by the defendant to explain where he was after ten o'clock on the night of the murder. This comes chiefly from members of the family; from his father and brothers.
It is agreed that the affidavit of the prisoner should be received as evidence of what his brother, Samuel H. Knapp, would testify if present. Samuel H. Knapp says, that, about ten minutes past ten o'clock, his brother, Frank Knapp, on his way to bed, opened his chamber door, made some remarks, closed the door, and went to his chamber; and that he did not hear him leave it afterwards. How is this witness able to fix the time at ten minutes past ten? There is no circumstance mentioned by which he fixes it. He had been in bed, probably asleep, and was aroused from his sleep by the opening of the door. Was he in a situation to speak of time with precision? Could he know, under such circumstances, whether it was ten minutes past ten, or ten minutes before eleven, when his brother spoke to him? What would be the natural result in such a case? But we are not left to conjecture this result. We have positive testimony on this point. Mr. Webb tells you that Samuel told him, on the 8th of June, "that he did not know what time his brother Frank came home, and that he was not at home when he went to bed." You will consider this testimony of Mr. Webb as indorsed upon this affidavit; and with this indorsement upon it, you will give it its due weight. This statement was made to him after Frank was arrested.
I come to the testimony of the father. I find myself incapable of speaking of him or his testimony with severity. Unfortunate old man! Another Lear, in the conduct of his children; another Lear, I apprehend, in the effect of his distress upon his mind and understanding. He is brought here to testify, under circumstances that disarm severity, and call loudly for sympathy. Though it is impossible not to see that his story cannot be credited, yet I am unable to speak of him otherwise than in sorrow and grief. Unhappy father! he strives to remember, perhaps persuades himself that he does remember, that on the evening of the murder he was himself at home at ten o'clock. He thinks, or seems to think, that his son came in at about five minutes past ten. He fancies that he remembers his conversation; he thinks he spoke of bolting the door; he thinks he asked the time of night; he seems to remember his then going to his bed. Alas! these are but the swimming fancies of an agitated and distressed mind. Alas! they are but the dreams of hope, its uncertain lights, flickering on the thick darkness of parental distress. Alas! the miserable father knows nothing, in reality, of all these things.
Mr. Shepard says that the first conversation he had with Mr. Knapp was soon after the murder, and before the arrest of his sons. Mr. Knapp says it was after the arrest of his sons. His own fears led him to say to Mr. Shepard, that his "son Frank was at home that night; and so Phippen told him," or "as Phippen told him." Mr. Shepard says that he was struck with the remark at the time; that it made an unfavorable impression on his mind; he does not tell you what that impression was, but when you connect it with the previous inquiry he had made, whether Frank had continued to associate with the Crowninshields, and recollect that the Crowninshields were then known to be suspected of this crime, can you doubt what this impression was? can you doubt as to the fears he then had?
This poor old man tells you, that he was greatly perplexed at the time; that he found himself in embarrassed circumstances; that on this very night he was engaged in making an assignment of his property to his friend, Mr. Shepard. If ever charity should furnish a mantle for error, it should be here. Imagination cannot picture a more deplorable, distressed condition.
The same general remarks may be applied to his conversation with Mr. Treadwell, as have been made upon that with Mr. Shepard. He told him, that he believed Frank was at home about the usual time. In his conversations with either of these persons, he did not pretend to know, of his own knowledge, the time that he came home. He now tells you positively that he recollects the time, and that he so told Mr. Shepard. He is directly contradicted by both these witnesses, as respectable men as Salem affords.
This idea of an alibi is of recent origin. Would Samuel Knapp have gone to sea if it were then thought of? His testimony, if true, was too important to be lost. If there be any truth in this part of the alibi, it is so near in point or time that it cannot be relied on. The mere variation of half an hour would avoid it. The mere variations of different timepieces would explain it.
Has the defendant proved where he was on that night? If you doubt about it, there is an end of it. The burden is upon him to satisfy you beyond all reasonable doubt. Osborn's books, in connection with what the young men state, are conclusive, I think, on this point. He has not, then, accounted for himself; he has attempted it, and has failed. I pray you to remember, Gentlemen, that this is a case in which the prisoner would, more than any other, be rationally able to account for himself on the night of the murder, if he could do so. He was in the conspiracy, he knew the murder was then to be committed, and if he himself was to have no hand in its actual execution, he would of course, as a matter of safety and precaution, be somewhere else, and be able to prove afterwards that he had been somewhere else. Having this motive to prove himself elsewhere, and the power to do it if he were elsewhere, his failing in such proof must necessarily leave a very strong inference against him.
But, Gentlemen, let us now consider what is the evidence produced on the part of the government to prove that John Francis Knapp, the prisoner at the bar, was in Brown Street on the night of the murder. This is a point of vital importance in this cause. Unless this be made out, beyond reasonable doubt, the law of presence does not apply to the case. The government undertake to prove that he was present aiding in the murder, by proving that he was in Brown Street for this purpose. Now, what are the undoubted facts? They are, that two persons were seen in that street, several times during that evening, under suspicious circumstances; under such circumstances as induced those who saw them to watch their movements. Of this there can be no doubt. Mirick saw a man standing at the post opposite his store from fifteen minutes before nine until twenty minutes after, dressed in a full frock-coat, glazed cap, and so forth, in size and general appearance answering to the prisoner at the bar. This person was waiting there; and whenever any one approached him, he moved to and from the corner, as though he would avoid being suspected or recognized. Afterwards, two persons were seen by Webster, walking in Howard Street, with a slow, deliberate movement that attracted his attention. This was about half-past nine. One of these he took to be the prisoner at the bar, the other he did not know.
