Bonner v. State, 314 Ga. 472

Victim Christine Cook was found dead at home on Oct. 17, 2012; jewelry, a Cadillac, and a television were missing. DNA from under Cook’s fingernails and from the Cadillac’s steering wheel matched Aurie Bonner III.
Police traced Cook’s missing wedding ring to a pawnshop; a customer said Bonner sold the ring for $7. Bonner was later arrested and gave recorded, inconsistent statements admitting to stealing the ring, the TV, and the Cadillac and describing a purported accomplice called “Top Dog.”
Police could not locate anyone known as “Top Dog.” Bonner’s Miranda‑waived interview and the DNA evidence formed core prosecution proof. A jury convicted Bonner of malice murder; he received life without parole.
On motion for new trial, Bonner argued trial counsel was constitutionally ineffective for (1) failing to subpoena Georgia Power for a billed-alibi, (2) failing to cross-examine several State witnesses (including the medical examiner and Sergeant Chapman), and (3) failing to call defense witnesses.
Trial counsel testified he had an investigator search for Georgia Power records and alibi witnesses but found nothing; he did not subpoena Georgia Power and explained cross‑examination and witness decisions as tactical.
The Supreme Court of Georgia applied Strickland and state precedent, credited the trial-court findings, and affirmed the conviction, concluding Bonner failed to show deficient performance or prejudice.

Issue	Bonner's Argument	State's Argument	Held
Failure to subpoena Georgia Power for alibi evidence	Subpoenaing Georgia Power may have produced exculpatory proof Bonner was paying a bill during the murder	Counsel’s investigator searched and found no proof; failure to subpoena was not shown to be patently unreasonable or likely to produce evidence	Counsel not ineffective; Bonner offered only speculation and failed Strickland’s deficient‑performance and prejudice prongs
Failure to cross‑examine Sergeant Chapman, medical examiner, and other witnesses	Counsel should have cross‑examined these witnesses to weaken State’s case	Choice of cross‑examination scope is strategic; counsel cross‑examined witnesses when useful and avoided pointless probes	Counsel’s decisions were strategic and not so unreasonable as to be ineffective; claim fails
Failure to present defense witnesses	Counsel should have presented unspecified witnesses to support an alibi/defense	Counsel searched for alibi witnesses but found none; calling witnesses is a tactical choice and Bonner did not identify witnesses or their expected testimony	Counsel not ineffective; Bonner failed to identify witnesses or show prejudice
