Arthur James Martin v. State of Florida, 151 So. 3d 1184

On October 28, 2009, Arthur James Martin drove (with codefendant Franklin Batie waiting in a car armed with a .45 and extended magazine) to an apartment complex, approached an SUV, and fired multiple rounds at driver Javon Daniels; Daniels died at the scene after sustaining a dozen gunshot wounds and defensive injuries.
Multiple eyewitnesses — including Batie and six others — identified Martin as the shooter; one eyewitness testified Martin tried to buy her silence after the killing.
Martin was convicted of first-degree murder in Duval County; the jury recommended death 9–3 and the trial court imposed death after finding three aggravators: prior violent felony, heinous/atrocious/cruel (HAC), and cold, calculated, and premeditated (CCP).
Penalty-phase mitigation included testimony from family and a defense psychologist who administered the WAIS-IV and scored Martin at 54 (low cognitive functioning); the court found low cognitive functioning and various other nonstatutory mitigators but assigned them limited weight.
Martin appealed, raising challenges to the trial court’s factual findings and weight assigned to mitigation (intellectual functioning; substance abuse), the HAC and CCP findings, and a Ring-based constitutional challenge to Florida’s death penalty scheme; the court affirmed conviction and sentence.

Issue	Martin's Argument	State's Argument	Held
Trial court misweighed low IQ/mental‑retardation evidence	WAIS‑IV score of 54 warrants greater mitigating weight and the court made erroneous factual findings about IQ testing	Court considered the IQ evidence and properly weighed it with other records; any misstatement was harmless	Affirmed — court’s factual findings supported by competent, substantial evidence; assigned weight not an abuse of discretion
Failure to consider substance‑abuse as mitigation	Court should have found and weighed Martin’s history of drug/alcohol abuse	Defense failed to propose substance‑abuse as a nonstatutory mitigator below, so court had no obligation to address it	Affirmed — defendant must present proposed nonstatutory mitigators to preserve appellate review
HAC (heinous, atrocious, cruel) finding	Multiple shots do not necessarily show torture or extraordinary cruelty	Victim was conscious, sustained defensive wounds, tracked around vehicle and shot repeatedly — supports HAC	Affirmed — competent substantial evidence supports HAC finding
CCP (cold, calculated, premeditated) finding	Killing was impulsive and a hastily‑obtained weapon was used; Martin had intellectual deficits	Martin retrieved gun, fired multiple rounds, tracked victim around vehicle and continued firing — shows reflection, planning, heightened premeditation	Affirmed (majority); concurrence disagreed — but majority found CCP supported by record
