Coroners' inquest procedures were delineated by statute and included describing in detail in the coroner's rolls every wound of a dead body, how many may be culpable, and people claiming to have found treasure who might be suspects. The precedent for punishment for treason was established by the conviction of a knight, David ab Gruffydd, who had turned traitor to the Welsh enemy, after fighting with Edward and being rewarded with land, during the conquest of Wales. He had plotted to kill the King. He was found guilty of treason by Parliament and condemned to be dragged at the heels of horses for being a traitor to his knightly vows, hanged by the neck for his murders, cut down before consciousness left him to have his entrails cut out for committing his crimes during the holy week of Easter, and his head cut off and his body divided into four parts for plotting against the King's life. The head was placed on the Tower of London and his body sections were placed in public view at various other locations in England. This came to be known as "hanging, drawing, and quartering". Prior to this the penalty had been imprisonment, usually followed by ransom. Trial by combat is now limited to certain claims of enfeoffment of large land holding and is barred for land held in socage, burgage, or by marriage. Assize is the usual manner of trial, but compurgation remains in the borough court long after it becomes obsolete in the royal courts. It came to be that defendants no longer request assizes but are automatically put to them.
