Ezekiel Williams, Jr. entered a negotiated plea of guilty to one count of felony theft by shoplifting OCGA § 16-8-14 b 3. He now appeals from the trial court’s order denying his motion to withdraw guilty plea, arguing manifest injustice arising out of claims of ineffective assistance of counsel. Discerning no error, we affirm. Once a sentence has been entered, a guilty plea may be withdrawn “only to correct a manifest injustice.” Footnote and punctuation omitted. Skinner v. State , 297 Ga. App. 828, 828-829 678 SE2d 526 2009. Where, as here, the defendant bases his motion to withdraw on an ineffective assistance of counsel claim, he bears the burden of showing that his attorney’s performance was deficient and that, but for counsel’s errors, a reasonable probability exists that he would have insisted on a trial. Harden v. Johnson , 280 Ga. 464 629 SE2d 259 2006. A court need not address both the deficient performance and prejudice prongs of this test if the showing on one prong is insufficient. In reviewing a lower court’s determination of a claim of ineffective assistance of counsel, we give deference to the trial court’s factual findings, which are upheld on appeal unless clearly erroneous; however, we review the lower court’s legal conclusions de novo. Footnotes and punctuation omitted. Navarrette v. State , 298 Ga. App. 637 680 SE2d 649 2009. The record shows that on May 14, 2009, Williams pled guilty to felony shoplifting, as above, at a negotiated plea hearing upon evidence which showed that while in a Best Buy store in November 2008, he concealed two X-Box play stations, valued at more than $300, in a box which was labeled as containing other items. Upon checking out, the store’s alarm went off. Police were called to the scene on the foregoing facts, and Williams’ arrest followed. On appeal, Williams appears to challenge the effectiveness of trial counsel see MacDonald v. McDonald , 156 Ga. App. 565, 566 1 275 SE2d 142 1980 enumeration of errors failing to clearly set out the errors “sought to be reviewed” shall be considered on appeal, because counsel failed to cause the State to dismiss the indictment, failed to seek suppression of the State’s evidence for lack of an arrest warrant, and coerced him into pleading guilty by “threatening him with his past” in advising him that being tried as a recidivist would expose him to a greater sentence.
a Williams asserts that trial counsel should have obtained the dismissal of the charges against him, presumably by successfully pursuing a motion to dismiss the same. While Williams contends that counsel was ineffective on this ground, he sets forth no legal basis in support thereof. Neither does he argue how he was harmed thereby. “A mere conclusory allegation, without more, is insufficient to establish ineffective assistance of counsel.” Mora v. State , 295 Ga. App. 641, 647 3 a 673 SE2d 23 2009.
