On September 29, 1770, Lilburn and Buchanan passed by the bridge of Boquhan when a mastiff or bull dog attacked them. They threw rocks at the dog. Sejeant Robertson came to the bridge to get the dog and Joseph Martine came to assist him. Lilburn and Buchanan struck Joseph Martine, who died the next day. They were arraigned for trial, and admitted attacking Martine, but the Court ruled that the two men could not be guilty of homicide because twelve hours passed between the attack and Martine's death. Had help been gotten, Martine might have lived.
