Gregory David Larkin v. State of Florida, 147 So. 3d 452

Background

Gregory David Larkin was tried, convicted, and sentenced to death for the April 2009 first-degree murders of his parents; he represented himself at trial after multiple Faretta colloquies and standby counsel was appointed.
Victims were found April 18, 2009; medical and forensic evidence (injuries consistent with blunt-force trauma, blood spatter, DNA on clothing, DNA on wine glass and baseball bat, and other scene evidence) supported time-of-death estimates and single-assailant theory.
Larkin traveled to Mexico April 12, returned April 18, was found at an airport hotel; his parents’ car was located at the airport; police recovered the victims’ jewelry in his backpack; grand theft charge dropped but evidence used at trial.
Forensic testing tied victims’ blood to clothing found near Larkin’s belongings and showed wearer DNA matching Larkin on shorts/sock; DNA also linked Larkin to a used wine glass; no usable fingerprints were found on the bat.
After guilt-phase convictions, defense counsel moved for a competency evaluation; one expert (Dr. Meadows) opined Larkin was delusional and incompetent, while two subsequent experts found him competent; the trial court allowed Larkin to continue representing himself and found him competent.
Jury unanimously recommended death for both counts; trial court found two aggravators (prior violent felony based on the other contemporaneous murder and HAC) and limited mitigation, and imposed death sentences for each murder.

Issues

Issue	Plaintiff's Argument (Larkin)	Defendant's Argument (State)	Held
1) Competency/self-representation at competency hearing	Trial court should have appointed counsel for competency proceedings; Larkin was incompetent and could not validly represent himself at that stage	The competency concern lacked specific factual support; Larkin’s courtroom performance showed competence; subsequent experts supported competency	Court: No abuse of discretion; no reasonable doubt of incompetence; Larkin competent and permitted to self-represent during competency proceedings
2) Ring v. Arizona challenge to Florida death-penalty statute	Ring invalidates Florida’s capital sentencing procedures because judge found aggravators	The jury unanimously recommended death and a prior violent felony aggravator (prior convictions exception) supports the sentences	Court: Ring claim rejected; unanimous jury recommendation and prior violent felony aggravator foreclose Ring relief
3) Sufficiency of the evidence for first-degree murder convictions	Evidence is circumstantial and lacks eyewitness, fingerprints on weapon, or clear motive—insufficient	Forensic, timeline, travel, possession of victims’ property, and scene evidence allow a rational juror to convict beyond a reasonable doubt	Court: Competent, substantial evidence supports convictions
4) Proportionality of death sentences	Death disproportionate given limited mitigation	Aggravators (HAC and prior violent felony) are among the most serious; mitigation minimal; jury unanimous	Court: Death sentences are proportionate and affirmed
