In February 1778, Ross accompanied Spooner on an extended trip to Princeton, bringing along a bottle of nitric acid given to him by Bathsheba with the aim of poisoning Spooner. Ross backed out of the plan and returned directly to his Linebrook home. While Ross and Spooner were in Princeton, Bathsheba invited two runaway British soldiers—escaped prisoners of war Pvt. Williams Brooks and Sgt. James Buchanan—to stay at the Spooner home and discussed ideas for killing her husband with them. When Spooner returned, she recruited them to assist her. She also wrote to Ross to inform him of these developments, and he returned to Brookfield on February 28. When Spooner returned home from a local tavern the following evening, Brooks committed the murder and Buchanan and Ross helped hide the body in the Spooners' well. Bathsheba distributed paper money from her husband's lockbox and articles of his clothing to the three men, who then took one of the Spooner horses to Worcester, fourteen miles away. Brooks and Buchanan spent the remainder of the night drinking, and the next morning Brooks showed off Spooner's silver shoe buckles engraved with his initials. Once the murder was discovered, the three men were arrested in Worcester within 24 hours. When Ross was discovered hiding in the attic of a tavern, he asked for a confessor. The trio implicated Bathsheba and three of her household servants in the crime. Brooks was charged with the assault on Spooner; Buchanan and Ross with aiding and abetting in the murder; and Bathsheba with inciting, abetting and procuring the manner and form of the murder. All were arraigned and pleaded not guilty. Trial and execution The Spooner murder case was the first capital case in the U.S. history. Robert Treat Paine, later the first Attorney General of Massachusetts, prosecuted the case. At the trial on April 24, 1778, the household servants testified for the prosecution. Levi Lincoln, later U.S. Attorney General under President Thomas Jefferson, defended the accused. Brooks and Buchanan had no defense to offer, having signed lengthy confessions. Though Ross had signed a similar confession, Lincoln argued that he had no intention of harming the deceased, was not aware of the plan until a few hours before the murder, had not assisted in the murder and pretended to support it to maintain his affair with Bathsheba. He argued that Bathsheba had a "disordered mind," that her actions
