So far as Morgan’s manuscript is concerned, it seems that a portion of it was already in the hands of Miller, and another portion secreted inside of a bed at the time he was arrested, so that not long after his disappearance what purports to be his book was published.

Nearly two years later, in August, 1828, three men were tried for conspiracy to kidnap and carry away Morgan.  At that time it was believed by many that Morgan was either simply detained abroad or in hiding, although it was strenuously insisted by others that he had been killed.  All that was ever known of his movements after he left the jail at Canandaigua on the night of September 11 was developed in the testimony taken at this trial.

One witness who saw the carriage drive past the jail testified that a man was put in by four others, who got in after him and the carriage drove away; the witness was near the men when they got into the carriage, and as it turned west he heard one of them cry to the driver, “Why don’t you drive faster? why don’t you drive faster?”

The driver testified that some time prior to the date in question a man came to him and arranged for him to take a party to Rochester on or about the 12th.  On the night in question he took his yellow carriage and gray horses about nine o’clock and drove just beyond the Canandaigua jail on the Palmyra road.  A party of five got into the carriage, but he heard no noise and saw no resistance, nor did he know any of the men.  He was told to go on beyond Rochester, and he took the Lewiston road.  On arriving at Hanford’s one of the party got out; he then drove about one hundred yards beyond the house, stopping near a piece of woods, where the others who were in the carriage got out, and he turned around and drove back.

Another man who lived at Lewiston and worked as a stage-driver said that he was called between ten and twelve o’clock at night and told to drive a certain carriage into a back street alongside of another carriage which he found standing there without any horse attached to it; some men were standing near it.  He drove alongside the carriage, and one or two men got out of it and got into his hack.  He saw no violence, but on stopping at a point about six miles farther on some of the men got out, and while they were conversing, some one in the carriage asked for water in a whining voice, to which one of the men replied, “You shall have some in a moment.”  No water was handed to the person in the carriage, but the men got in, and he drove them on to a point about half a mile from Fort Niagara, where they told him to stop; there were no houses there; the party, four in number, got out and proceeded side by side towards the fort; he drove back with his carriage.
