Wilson was tried on 25 September 1862 before
Mr Justice Byles, again defended by Montagu Williams. During the trial, it was alleged that seven people with whom Wilson had lived as a nurse had died after rewriting their Wills to leave her some money, but this evidence was not admitted. Almost all had suffered from
gout. Evidence of colchicine poisoning was given by toxicologist
Alfred Swaine Taylor, the defence being that the poison could not be reliably detected after so long. In summing up, the judge said to the jury: "Gentlemen, if such a state of things as this were allowed to exist no living person could sit down to a meal in safety". Wilson was found guilty and sentenced to
hang. A crowd of 20,000 turned out to see her execution at
Newgate Gaol on 20 October 1862. After the trial, Byles asked Williams to come to his chambers, where he told him: "I sent for you to tell you that you did that case remarkably well, but it was no good; the facts were too strong. I prosecuted Rush for the murder of Mr Jermy, I defended
Daniel Good, and I defended several other notable criminals when I was on the Norfolk Circuit, but if it will be of any satisfaction to you, I may tell you that in my opinion you have to-day defended the greatest criminal that ever lived." ==Public reaction to crimes==
