Warren v. State, 314 Ga. 598

Warren and co-defendant Dakota White were indicted for murder, aggravated assault, concealing a death, and tampering with evidence; White was convicted earlier and his convictions affirmed.
White testified that he and Warren lured Samuel Poss to White’s house, strangled him, and Warren stabbed Poss multiple times; forensic pathology showed sharp-force injuries plus strangulation caused death.
Two knives were recovered: the brown-handle knife had White’s DNA on the handle (not Poss or Warren); the blue-handle knife had a mixed profile that could not exclude Warren or Poss and excluded White.
Warren wrote a jail letter largely consistent with White’s account but sought to minimize his role; at trial Warren testified and denied stabbing Poss, asserting fear and alternative culpability by White.
During closing the prosecutor said proof beyond a reasonable doubt is not a "mathematical certainty" and is not "95 percent, 85 percent"; defense counsel did not object. Warren was convicted and sentenced to life without parole.
On motion for new trial Warren raised ineffective-assistance claims: (1) counsel failed to object to the percentage remark; (2) counsel inadequately advised him about the decision to testify. The trial court denied relief and the Supreme Court of Georgia affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether counsel was ineffective for not objecting to prosecutor saying "not 95%, 85%" when defining beyond a reasonable doubt	Warren: counsel should have objected; comment misstated law and could mislead jury	State: remark was at most inadvisable; trial instructions cured any error and evidence was strong	No ineffective assistance — even if deficient, no prejudice given strong evidence and accurate jury instructions (Draughn distinction)
Whether counsel was ineffective for failing to adequately advise Warren about his right to testify	Warren: counsel needed to give clear advice and recommend against testifying if counsel believed testimony would be detrimental	State: counsel discussed pros/cons multiple times and left the tactical decision to Warren, as is customary	No ineffective assistance — advising pros/cons and leaving the decision to the defendant falls within reasonable professional norms
Whether cumulative error requires reversal	Warren: combined effect of both alleged deficiencies prejudiced the outcome	State: only two claims were raised and neither proved deficient or prejudicial individually	No cumulative prejudice — multiple errors analysis applies only when multiple errors are shown, which Warren did not establish
