Merck v. State, 124 So. 3d 785

Background

Merck, Jr. was convicted of first‑degree murder for stabbing James Newton outside a Pinellas County bar in 1991, and was sentenced to death after a third penalty phase.
The Florida Supreme Court previously affirmed the conviction but reversed death sentences twice due to penalty phase errors, with Merck III affirming the third sentence in 2007.
Merck filed a postconviction motion under Rule 3.851, asserting multiple claims including ineffective assistance of counsel at guilt and penalty phases, and other trial and sentencing errors; some claims were tried with an evidentiary hearing, others were denied.
Merck also filed a habeas corpus petition challenging the death sentence and related constitutional issues; a pro se all writs petition alleging ineffective postconviction counsel was denied.
The trial court denied most postconviction claims; the circuit court’s rulings were appealed to this Court, which affirmed the denial of relief and denied the habeas petition.
The court applied Strickland v. Washington and mixed standard review, deferring to factual findings supported by evidence but reviewing legal conclusions de novo.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Guilt-phase ineffective assistance (two defenses)	Merck asserts counsel erred by presenting two defenses (identity doubt and voluntary intoxication) and failing to object to a mischaracterized defense.	Merck contends counsel’s strategy was deficient and prejudicial because it misled jurors and diluted defense.	No deficiency or prejudice; strategic dual defenses were permissible and not outside reasonable professional norms.
Penalty-phase juror challenges	Merck argues counsel erred by not striking two jurors predisposed to favor death.	Merck contends jurors displayed bias that should have led to challenges for cause or peremptory strikes.	Jurors were not biased or predisposed against Merck; no prejudice from failure to strike.
Minor participant evidence in penalty phase	Merck contends counsel failed to proffer evidence showing he was a minor participant under section 921.141(6)(d).	Merck argues the evidence would have shown lesser participation and supported mitigation.	Evidence would have raised fingering doubt and was inadmissible; no prejudice from not proffering.
Mental health mitigation testimony	Merck claims counsel was ineffective for not presenting Dr. Maher to testify on statutory mitigators.	Merck contends the absence of Dr. Maher testimony prejudiced the penalty phase because statutory mitigators could have been found.	No prejudice; other mitigation evidence and Spencer hearing findings supported rejection of mitigators, and additional testimony would have been cumulative and potentially harmful.
Statutory mental mitigators and instructions	Merck argues counsel should have requested statutory mitigators (extreme mental or emotional disturbance; impaired capacity).	Merck asserts absence of evidence supported instructing jurors on those mitigators; no deficiency to present absent evidence.	No deficiency; lack of evidence to support those mitigators and the court’s prior determinations were preserved.
