OPINION OF THE COURT
Appellant, Carl Lee, was charged with murder in connection with the gangwar shooting death of Kieth Lawrence, a thirteen year old boy. Pleading not guilty, appellant proceeded to trial in the court of common pleas. While voir dire examination was being conducted and after several jurors had been selected, appellant informed his counsel of his desire to withdraw his plea of not guilty if a plea bargain with the Commonwealth could be arranged. Negotiations for such an agreement were successful. Appellant agreed to plead guilty to murder generally in exchange for the District Attorney’s certification to the court that the degree of guilt rose no higher than murder in the second degree and his recommendation of a sentence of imprisonment for not less than six and one-half nor more than twenty years. The parties then revealed the terms of the plea agreement to the trial court which, after an extensive colloquy with appellant and counsel, accepted the plea of guilty. Upon receiving the Commonwealth’s evidence, the court con- *327 eluded that appellant was guilty of murder in the second degree, and accepted the Commonwealth’s recommendation with respect to sentencing.
In this direct appeal from the judgment of sentence, appellant’s sole argument is that the colloquy conducted by the court was insufficient to enable appellant intelligently and voluntarily to enter a plea of guilty. * We find this argument to be without merit and, therefore, affirm.
The exhaustive colloquy in the instant case, which consumed fifty-two pages of typed transcript, conformed in every respect to the guidelines which have been established to insure that a defendant who pleads guilty does so voluntarily and intelligently with full knowledge of the nature of a plea of guilty and the consequences which flow therefrom. See
Boykin v. Alabama,
It is clear that appellant chose to plead guilty in order to benefit from the plea bargain which he, himself, had requested his counsel to arrange. This fact, in itself, is a strong indicator that the plea was voluntarily made. See
Commonwealth v. Alvarado,
We, therefore, find that appellant has failed to sustain his burden of demonstrating that his plea of guilty was not knowingly, intelligently, and voluntarily entered.
Commonwealth v. Ward,
Judgment of sentence affirmed.
Notes
This appeal was not preceded by the filing of a petition for withdrawal of the guilty plea nor by post-trial motions. We reiterate that, in cases such as the one at bar where the only challenge to the proceedings in the trial court is directed to the validity of the guilty plea itself, the proper procedure is first to file with that court a petition to withdraw the plea.
