[1-3] The plaintiff in error, hereinafter called the accused, was a penitentiary convict, and murdered the guard who had him in custody. He was convicted of the offense and sentenced to be electrocuted, which is the only punishment provided by statute. The jury had no option to fix any less punishment. Code, section 5051. It was essential for the Commonwealth, in a proceeding for this offense, to prove that, at the time of the homicide, the accused was a convict; and the only error assigned is that the record does not show that he is the same Ernest Brown as the Ernest Brown who was convicted of a felony in Surry county and sentenced to a term of years in the penitentiary. The assignment of error is without merit. The accused was indicted as Ernest Brown, alias “Fern,” and the indictment charged that he had been previously convicted of a felony in the Circuit Court for the county of Surry, and sentenced to a term of five years in the penitentiary, and that, at the time of the homicide, he was undergoing his punishment as a member of the State convict road force, at the camp in Orange county. In support of the charge of such conviction, the Commonwealth introduced a certified copy of the judgment and order of condemnation of “Ernest Brown, alias ‘Fern’ ” from the Circuit Court of Surry county. The trial court certified the facts, not merely the evidence, established in the case, and, among them, “that Ernest Brown was, on the 1st day of March, 1921, in the custody of Walter E. Snow and D. N. Kyger, guards of the penitentiary of Virginia, working at a stone quarry in Orange county, *608Va.,” and tha,t the certified copy of the order of the Circuit Court of Surry county above referred to was “the paper under which the said Ernest Brown was held in the said custody and under which he was received into said camp as a convict.” This abundantly identifies the accused as the convict under the judgment aforesaid of Surry county. The murder was fully proved, and is not here denied. It is plain that the judgment complained of must be affirmed.
