The following is a summary of the facts: On the night of the 6th of April, 1830, the town of Salem was visited by a desperado who entered the house of Joseph White, a wealthy and respectable citizen, and murdered him in his bed. The citizens formed a vigilance committee and worked without avail until there came a rumor that a prisoner in the New Bedford jail knew something of the affair. He was accordingly brought up before the grand jury, and on his testimony Richard Crowningshield, of Danvers, was indicted. A few weeks later Captain Joseph Knapp, a shipmaster of good character, received a strange note from Belfast, Maine, which was signed by Charles Grant, Jr. This note threatened exposure unless money was forwarded. Knapp could not understand it. He showed it to his sons, Francis and Joseph, Jr., who resided in Wenham. The wife of the latter was a niece of the late Mr. White, and was his housekeeper prior to the murder. When Joseph saw the letter he said it contained trash, and told his father to hand it to the vigilance committee. When they received the letter they sent to Belfast to find the writer. This proved to be one Palmer, who had been in state prison and who was intimate with Crowningshield. He said he saw, on the 2nd of April, Frank Knapp and a man, Allen, in company with Crowningshield, and that he heard the latter say that Frank Knapp wished them to kill Mr. White, and that Joseph Knapp would pay them one thousand dollars. After the murder the Knapps reported that, on the 27th of April, they had been attacked by robbers on their way from Salem to Wenham. The purpose of this will be seen in what follows. On the testimony of Palmer the Knapps were held for investigation, and on the third day Joseph made a full confession of the murder and of the fabrication of the robbery story. He had found that Mr. White intended to leave his (Knapp's) wife but fifteen thousand dollars by will, and he thought that if he died intestate she would come in for one-half of the estate, as the sole representative of Mr. White's sister. Under this impression he determined to destroy the will. Frank agreed to hire the assassin, and he (Joseph) was to pay one thousand dollars for the deed. Crowningshield was hired; he entered the house by a window and committed the murder. So cool was he that, as he said, he paused to feel the pulse of the old man to be sure he was dead. Frank was waiting the issue, while Joseph, who had got the will, was in Wenham at his home. When Crowningshield heard that the Knapps were in custody, and that Joseph had confessed, he committed suicide in his cell.
