Rigsby v. State, 306 Ga. 38

Victim Betty Smith was found dead Sept. 6, 2010; shot twice and placed in a chest; her pet ferret was also killed. Evidence tied .38-caliber bullets recovered from the scene to a revolver that Johnny Rigsby was carrying when arrested on Sept. 4, 2010.
Rigsby was arrested on unrelated reckless-driving/drug matters Sept. 4 and again later that day; his fingerprint was found on a bloody kitchen knife and DNA linked scissors to Smith.
Two days after the body was found, during a booking interview where an investigator explained malice vs. felony murder after Rigsby asked, Rigsby stated, "I only killed — they said I only killed one person." The statement was recorded and played to the jury.
Trial (Aug. 2012) resulted in convictions for malice murder (life without parole), aggravated assault-family violence, aggravated cruelty to animals, and a firearms count; felony-murder was vacated by operation of law.
Post-trial issues on appeal: (1) whether the post-arrest booking statement should have been suppressed; (2) whether voluntary manslaughter instructions/ verdict form were improper or confusing; (3) whether trial counsel was ineffective for failing to timely object to the verdict form.

Issue	Rigsby’s Argument	State’s Argument	Held
Admissibility of post-arrest statement made at booking	Investigator’s explanation of charges was likely to elicit an incriminating response; not covered by booking exception; statement should be suppressed	Statement was a spontaneous, voluntary outburst, admissible despite prior invocation of counsel	Court affirmed admission: investigator stopped interrogation after counsel request; Rigsby initiated booking discussion and his remark was voluntary and spontaneous
Jury instruction and verdict form on voluntary manslaughter	Charge/instructions and verdict form were confusing and prevented full consideration; blank lesser-offense lines invalidated verdict	Jury was given the instruction and form; State argued no reversible error and instruction was not required	Court held Rigsby was not entitled to a voluntary-manslaughter instruction on the presented theories; any errors regarding the form were harmless
Ineffective assistance for failure to timely object to verdict form	Counsel’s omission prejudiced Rigsby’s ability to obtain lesser-included verdict	Failure to object was not shown to have affected outcome; no prejudice under Strickland	Court rejected ineffective-assistance claim: Rigsby cannot show deficient performance likely affected trial outcome
