State v. O'Neal, 392 S.W.3d 556

O’Neal was convicted in the Randolph County Circuit Court of first-degree murder, first-degree assault, and two armed criminal action counts for the Dawn Kelly shooting in Howard County on February 10, 2007.
O’Neal challenged admission of statements from his third interrogation, claiming he had invoked his right to remain silent before that interrogation.
There were three Miranda-rights interrogations on February 10; the third interrogation produced a changed account and was admitted at trial along with the prior two interviews.
A pre-trial suppression motion to exclude the third-interrogation statements was denied; the bench trial followed with the challenged statements admitted and the guilty verdicts returned.
O’Neal’s appellate arguments focused on whether his invocation of the right to remain silent was honored and whether the preservation of objections to suppression was proper; the court conducted a plenary review of the suppression issue and ultimately affirmed the conviction.
The court held that the admission of the third-interrogation statements was harmless beyond a reasonable doubt given the weight of unchallenged evidence of guilt.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Did third interrogation violate Fifth Amendment rights by an invocation of silence?	O’Neal argued he unequivocally invoked silence before the third interrogation.	State argued interrogation followed a scrupulous honoring of silence and a fresh Miranda warning.	No reversible error; interrogation upheld as scrupulously honoring silence.
Was the suppression issue properly preserved for review?	Objections were preserved via mutual understanding that suppression arguments remained on record.	State contends waiver or plain-error review should apply due to trial objections.	Preserved for plenary review; not limited to plain error.
If error occurred, was the admission of the third interrogation’s statements harmless beyond a reasonable doubt?	Admission of statements could have biased the verdict against O’Neal.	Overwhelming evidence of guilt renders the error harmless.	Harmless beyond a reasonable doubt; affirmance of conviction.
