L. C. Robertson was found guilty by a jury of manslaughter and sentenced to imprisonment for a term of ten years. We affirm.
The sufficiency of the evidence to sustain the conviction is not challenged. A jury reasonably could find that on December 7, 1969, appellant inflicted fatal wounds upon his wife by use of a butcher knife.
Appellant’s first point is that the trial court erred in permitting the testimony of Demmetrist Perryman, the son of the deceased, because “there was no showing on voir dire that [he] understood the nature of the oath administered in courts of law and the true nature of the results of not telling the truth under oath.”
At a hearing out of the presence and hearing of the jury, Demmetrist testified that he was nine years of age and in the fourth grade at school. He stated that he remembered what occurred when his mother was killed, that he would tell the truth, and when one did not tell the truth it would be a lie. He also testified that if one told a lie he would “get put in jail,” that he believed in God, and that if he told a lie God would punish him.
The determination of the competency of a witness is a matter within the sound discretion of the trial court, State v. Jones,
We have read the testimony of Demmetrist given at the preliminary hearing and at trial. It was straightforward and the answers were responsive. In view of our review of his testimony and the answers given by Demmetrist as to his belief in God and the punishment to be expected for telling a lie, we conclude that the trial court did not err to the prejudice of appellant in permitting him to be sworn and testify as a witness for the State.
Appellant’s second and last point is that the trial court erred in denying his motion for a new trial because “Demmetrist Per-ryman * * * was being ‘coached’ during his testimony.”
At a hearing on the motion for new trial, Irma Jean Robertson, appellant’s daughter, testified that “Demmetrist was asked if he ever saw his mother with a knife after his daddy and [his grandmother] shook her head this way, and Dem-metrist said no.” She also stated the grandmother shook her head several times, but on cross-examination she stated that the above question was the only one she remembered where the grandmother shook her head. The trial judge commented that he was “always watching the people” in the courtroom, and that “some people subconsciously move their heads one way or another as to which way they want a question answered or not.” He further commented that he remembered the grandmother and where she was sitting, and that he “did not observe any of this going on.” Neither the grandmother nor Demmetrist testified at the hearing on the motion for new trial.
Appellant relies primarily on State v. Barker,
The granting of a mistrial because of the conduct of a witness or spectator during the course of a trial is within the sound discretion of the trial court, State v. Anderson, Mo.,
The judgment is affirmed.
PER CURIAM:
The foregoing opinion by STOCK ARD, C., is adopted as the opinion of the Court.
All of the Judges concur.
