Parker v. State, 309 Ga. 736

Background

In September 2017 Vraimone Parker fatally shot Kwame Chubbs and grazed Chubbs’s girlfriend, Eva Robinson; Parker was arrested nearby with a pistol later matched to the wounds.
A Fulton County grand jury indicted Parker on malice murder, multiple felony-murder counts, aggravated assault, and firearm-possession counts; an August 2018 jury convicted him of all charges and he received life without parole plus consecutive terms for aggravated assault and a firearm-related prior-conviction enhancement.
Parker raised a not-guilty-by-reason-of-insanity defense; the trial heard three expert opinions: the defense expert (schizoaffective disorder, chronic psychosis), the State expert (psychosis attributable to substance abuse), and the court-appointed expert (cannabis-induced psychotic disorder).
At trial a detective made a brief remark that Parker “didn’t speak,” and the court-appointed expert briefly stated Parker “knew what he was doing,” producing motions for mistrial; the court denied mistrials and gave curative instructions.
The trial court excluded testimony about a second meeting between the defense expert and Parker as a discovery sanction because the meeting wasn’t disclosed in the expert report; the court allowed the jury to learn only that a second meeting had occurred and elicited a bench proffer about its substance.
Parker also challenged trial counsel’s handling of prior-conviction evidence (arguing counsel should have stipulated to felon status or redacted irrelevant allegations) and claimed ineffective assistance; the court rejected prejudice arguments.

Issues

Issue	Parker's Argument	State's Argument	Held
Whether mistrial was required after a detective’s remark that Parker “didn’t speak”	The remark was an improper comment on Parker’s silence and warranted a mistrial	The comment was non-responsive, made in passing, and curative instruction cured any harm	Denied; trial court did not abuse discretion — juries presumed to follow curative instructions
Whether mistrial was required after the court-appointed expert said Parker “knew what he was doing”	The expert testified on the ultimate issue (criminal responsibility) and the unsolicited remark required a mistrial	Testimony was cut off, unsolicited, and the court gave a specific curative instruction; jury can consider expert diagnoses but ultimate issue is for jury	Denied; no abuse of discretion given prompt curtailment and curative instruction
Whether exclusion (discovery sanction) of testimony about defense expert’s second meeting with Parker was reversible error	Excluding that testimony undermined Flores’s opinion and misled jury about the basis for her opinion	Flores failed to disclose the meeting in her report; exclusion authorized under OCGA §17‑16‑6 and the court received a bench proffer that the second meeting did not change opinion	Denied; no harmful error — jury knew two meetings occurred and defendant failed to proffer specific additional testimony showing prejudice
Whether trial counsel was ineffective for not stipulating or redacting prior‑conviction evidence	Counsel should have stipulated to felon status or redacted inflammatory allegations to avoid prejudice to insanity defense	Prior‑conviction evidence was unlikely to inflame jury given the overwhelming evidence of shooting and because prior convictions were relevant to firearm‑possession counts	Denied; even if performance was deficient, Parker showed no reasonable probability of a different outcome under Strickland; cumulative prejudice claim fails
