for the Court:
¶ 1. Amy Danielle Wilkerson appeals the Jackson County Circuit Court’s dismissal of her motion for post-conviction relief (PCR). On appeal, she argues (1) her guilty plea was involuntary, and (2) her trial counsel was ineffective. Wilkerson’s first argument is procedurally barred because she failed to raise the voluntariness of her plea in her PCR motion. But this procedural bar aside, we find Wilkerson was properly advised of the consequences of her plea, and no error by her counsel rendered her plea involuntary. Finding no error, we affirm.
FACTS
¶ 2. During the early morning hours of July 18, 2005, the parents of eight-week-old Tristen Chin followed their normal routine. Tristen’s mother awoke and played with him before going to work. His father then dropped Tristen off at Wilkerson’s home for Wilkerson to babysit him that day. Tristen was in perfect health when his father left him under Wilkerson’s care.
¶ 3. About five hours later, 911 received a call reporting that Tristen was not breathing. Responding paramedics arrived to find Wilkerson attempting to perform CPR on the infant. Tristen was taken to the hospital and died a short time later.
¶4. Wilkerson gave several conflicting accounts of the events surrounding Tris-ten’s death. At the hospital, Wilkerson told Tristen’s mother that Tristen had been injured while riding in the car. Wilkerson later told police detectives that Tris-ten’s injury occurred when he fell from the couch and hit his head. Wilkerson eventually confessed that her “couch story” was false and that she had shaken Tristen to death.
¶ 5. A Jackson County grand jury indicted Wilkerson for capital murder.
¶ 6. Exactly three years later, Wilkerson filed a PCR motion arguing her trial attorneys were ineffective. The circuit court found it plain from reviewing Wilkerson’s motion that she was not entitled to relief. See Miss.Code Ann. § 99-39-11(2) (Supp. 2011). The circuit court summarily dismissed her PCR motion without holding an evidentiary hearing. Wilkerson now appeals.
STANDARD OF REVIEW
¶ 7. In considering the dismissal of a PCR motion, we review the trial court’s findings of fact for clear error and its determinations of' law de novo. Williams v. State,
DISCUSSION
I. Voluntariness of Plea
¶ 8. Wilkerson argues her guilty plea was involuntary because: (1) the circuit court failed to explain to her the minimum and maximum sentences she faced; (2) she was not given an opportunity to explain during her plea colloquy her “own version of the alleged [baby] shaking”; and (3) she only had thirty minutes to contemplate her plea.
A. Procedural Bar
¶ 9. Wilkerson failed to raise any of the issues relating to the voluntariness of her plea in her PCR motion, which is a procedural bar. See Foster v. State,
B. Legal Standard
¶ 10. A guilty plea is binding if entered voluntarily, knowingly, and intelligently. Alexander v. State,
¶ 11. In assessing the voluntariness of a plea, the thoroughness of the trial court’s interrogation during the plea colloquy “is the most significant evidence of all.” Gardner v. State,
C.Minimum and Maximum Sentences
¶ 12. Wilkerson claims “the record is totally silent as to any explanation given to [her] about the possible mínimums and máximums in her plea.” Yet in her plea petition, she hand wrote that “Life” was the maximum sentence for murder. And at her guilty-plea hearing, Wilkerson acknowledged she understood “the only punishment for [depraved-heart murder] is life in the penitentiary.” The trial judge also emphasized to her that she “would not be eligible for parole considerations until the age of 65.” He explained, “Your age now is 31, so you are looking at some 34 years in the penitentiary [at] a minimum.” When asked if she understood the terms of her sentence, Wilkerson replied, ‘Wes, sir.”
¶ 13. We find the trial judge thoroughly explained to Wilkerson the consequences of her plea. And Wilkerson’s statements under oath evince she understood the minimum and maximum penalties she faced. The bare assertions she now makes cannot overcome the presumption of truth attached to her sworn in-court statements. See Hill v. State,
D.Factual Basis
¶ 14. Wilkerson also seems to challenge the factual basis for her plea. But she makes no argument that the State’s factual basis contained any inaccuracies. She instead argues that for her plea to be valid, the circuit court had to
¶ 15. Before accepting a guilty plea, the circuit court must determine there is a factual basis supporting the plea. Pegues v. State,
¶ 16. Wilkerson pled guilty to depraved-heart murder. Mississippi Code Annotated section 97-3-19(l)(b) defines depraved-heart murder as the unlawful killing of a human being “done in the commission of an act eminently dangerous to others and evincing a depraved heart, regardless of human life, although without any premeditated design to effect the death of any particular individual[.]”
¶ 17. During Wilkerson’s plea colloquy, she agreed to the factual basis recited by the State. In so doing, she acknowledged she had provided several conflicting accounts of the child victim’s (Tristen’s) injury. These included that Tristen was hurt while riding in the car and that he had fallen off of the couch. She ultimately admitted to law enforcement she had shaken Tristen and her “couch story” was not true. She further acknowledged Tristen had died as a result of her shaking him. When specifically asked by the circuit judge whether she had shaken Tristen, Wilkerson responded, “Yes, sir.” We also note that in her plea petition she admitted, “I shook the child.”
¶ 18. A factual basis may be established by an admission of the defendant. Jones v. State,
E. Time to Contemplate Plea
¶ 19. Wilkerson claims her plea was involuntary because she only had thirty minutes to decide whether to plead guilty. Yet neither affidavit attached to her PCR motion supports this claim. Thus, we find Wilkerson falls far short of meeting her burden on this issue.
II. Effectiveness of Trial Counsel
¶ 20. Wilkerson suggests her trial attorneys were ineffective. She argues they were deficient by failing to (1) sufficiently investigate her case, (2) communicate with her about the State’s evidence, and (3) offer mitigation testimony on her behalf.
¶ 21. To prevail on her claim of ineffective assistance of counsel, Wilkerson must show: (1) her counsel’s performance was deficient, and (2) the deficiency was prejudicial. Strickland v. Washington,
¶ 22. To establish prejudice, Wilkerson must show a “reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Id. at 694,
¶ 23. “[Wlhere a defendant voluntarily pleads guilty to an offense, he waives all non-jurisdictional rights incident to trial[.]” Hill,
B.Pretrial Preparation
¶ 24. Wilkerson suggests her attorneys’ alleged lack of pretrial preparation rendered her plea involuntary. But she does not explain how information yielded by additional investigation would have aided in her defense or resulted in her deciding to exercise her right to a jury trial. See Burrough,
C.Communication
¶ 25. Wilkerson next contends her attorneys were ineffective for not adequately communicating with her. She alleges her attorneys left her “in the dark” about the State’s evidence in the case. Again she fails to plead her allegation with the required specificity. See Jenkins,
D.Mitigation Testimony
¶ 26. Finally, Wilkerson suggests her counsel was ineffective because “[t]here was absolutely no mitigation testimony proffered [on her] behalf.” Because Wilkerson’s argument does not relate to
CONCLUSION
¶ 27. We find from reviewing Wilkerson’s guilty-plea transcript, her PCR motion and the accompanying affidavits that the trial judge advised her of the consequences of her guilty plea, and she voluntarily pled guilty. Wilkerson has not shown that any alleged error by her trial counsel rendered her plea involuntary or that her attorneys were constitutionally ineffective. We affirm the circuit court’s summary dismissal of her PCR motion.
¶ 28. THE JUDGMENT OF THE JACKSON COUNTY CIRCUIT COURT DISMISSING THE MOTION FOR POST-CONVICTION RELIEF IS AFFIRMED. ALL COSTS OF THIS APPEAL ARE ASSESSED TO THE APPELLANT.
Notes
. See Miss.Code Ann. § 97 — 3—19(2)(f) (Rev. 2006).
. See Miss.Code Ann. § 97 — 3—19(1 )(b) (Rev. 2006).
. She claims: “The colloquy was precise and textbook, and all points were covered but one. The one missing was [Wilkerson's] own version of the alleged shaking of [the child victim].”
. This is so even though Wilkerson raises the issue in her brief under the heading dealing with the voluntariness of her plea. We find her argument does not relate to whether she was' advised of the nature of the charge and consequences of her plea.
