¹ See Tex. R. App. P. 47.4. paragraphs contained in one of the indictments. Campbell now appeals his convictions of five years’ and fifteen years’ confinement. We will affirm. Campbell’s court-appointed appellate counsel has filed a motion to withdraw as counsel and a brief in support of that motion. In the brief, counsel avers that, in his professional opinion, the appeal is frivolous. Counsel’s brief and motion meet the requirements of Anders v. California by presenting a professional evaluation of the record demonstrating why there are no arguable grounds for relief. 386 U.S. 738, 87 S. Ct. 1396 (1967). We gave Campbell the opportunity to file a pro se brief, and he did not file one. The State also did not file a brief. As the reviewing court, we must conduct an independent evaluation of the record to determine whether counsel is correct in determining that the appeal is frivolous. See Stafford v. State, 813 S.W.2d 503, 511 (Tex. Crim. App. 1991); Mays v. State, 904 S.W.2d 920, 923 (Tex. App.—Fort Worth 1995, no pet.). Only then may we grant counsel’s motion to withdraw. See Penson v. Ohio, 488 U.S. 75, 82–83, 109 S. Ct. 346, 351 (1988). Because Campbell entered an open plea of guilty, our independent review for potential error is limited to potential jurisdictional defects, the voluntariness of Campbell’s plea, error that is not independent of and supports the judgment of guilt, and error occurring after entry of the guilty plea. See Monreal v. State, 99 S.W.3d 615, 620 (Tex. Crim. App. 2003); Young v. State, 8 S.W.3d 656, 666–67 (Tex. Crim. App. 2000).
