ORDER
PER CURIAM.Defendant Darryl Blair appeals the judgment entered after the trial court convicted him of child abuse in violation of Section 568.060, RSMo 1994, and endangering the welfare of a child in violation of Section 568.045, RSMo 1994. In his sole point on appeal, Defendant claims the trial court plainly erred in trying his case without a jury because the court did not ascertain that his waiver was knowing and voluntary.
We have reviewed the record on appeal. The transcript recites Defendant’s waiver of a jury trial and the legal file contains a written memorandum signed by Defendant indicating a voluntary and knowing waiver. Rule 27.01(b); State v. Butler, 415 S.W.2d 784, 785 (Mo.1967); State v. Turnbough, 604 S.W.2d 742, 746 (Mo.App. E.D.1980). When waiving the right to a jury trial, Defendant’s counsel indicated it was a matter of trial strategy and it was the desire to have a bench trial due to the nature of the charges. Finally, we note Defendant does not claim he did not knowingly and voluntarily waive a jury trial.
An extended opinion would serve no jurisprudential purpose. We affirm the judgment pursuant to Rule 30.25(b).
