731 S.E.2d 761 | Ga. | 2012
This is the second appearance of this case before this Court. In December 2005, Appellant Jamerson Mangrum was found guilty of numerous crimes related to the death of 15-year-old Katie Hamlin in July 2002, including three counts of felony murder, two counts of aggravated child molestation, and one count each of rape, abandoning a dead body, concealing a death, and tampering with evidence. After his motion for new trial was denied, Appellant obtained new counsel and appealed to this Court, alleging numerous grounds for reversal. In Mangrum v. State, 285 Ga. 676 (681 SE2d 130) (2009), we rejected all of his arguments except for his claim of ineffective assistance of trial counsel, which we remanded to the trial court for a hearing. See id. at 683.
To prevail on a claim of ineffective assistance of counsel, Appellant
must show that his trial counsel provided deficient performance and that, but for that unprofessional performance, there is a reasonable probability that the outcome of the proceeding would have been different. See Strickland v. Washington, 466 U. S. 668, 687, 694 (104 SC 2052, 80 LE2d 674) (1984). In examining an ineffectiveness claim, a court need not “address both components of the inquiry if the defendant makes an insufficient showing on one. In particular, a court need not determine whether counsel’s performance was deficient before examining the prejudice suffered by the defendant as a result of the alleged deficiencies.” Id. at 697.
Watkins v. State, 289 Ga. 359, 362 (711 SE2d 655) (2011) (citation omitted).
Appellant contends that his trial counsel was deficient in failing to procure and offer medical evidence concerning the supposed causal link between the victim’s mental condition and medications and her death. To show prejudice from this alleged deficiency, however,
Judgment affirmed.
The State had provided Berry with a list of the prescribed medications, although a toxicology report showed that the victim was not taking Risperdal when she died.
On the day of the hearing, Appellant filed a motion to permit the supplementation of evidence and a motion for scientific testing, but the trial court also denied those motions in the April 18 order. Appellant has not appealed that ruling.
