The punishment for this crime by the common law is a forfeiture of all property and honors and attainder of blood; also the death penalty.21

Blackstone: The offender shall be drawn to the gallows, and not be carried or walk, though usually (by connivance at length ripened by humanity into law), a sledge or hurdle is allowed to preserve the offender from the extreme torment of being dragged on the ground or pavement. He shall be hanged by the neck, and then cut down alive; his entrails shall be taken out and burned while he is yet alive; his head shall be cut off and his body divided into four parts. His head and quarters shall be at the disposal of the king.22
