297 Ga. 191
Ga.2015Background
- In 2005 Gregory Walker was convicted of malice murder; jury sentenced him to death; convictions and sentence were affirmed on direct appeal. Walker later filed habeas in 2008. After hearings the habeas court vacated the death sentence but left convictions intact; the Warden appealed.
- At the underlying crime scene Walker and accomplices kidnapped and executed Janeika Murphy; facts of the homicide were not disputed in the habeas proceedings.
- During the capital sentencing phase trial, defense counsel hired a mitigation specialist (William Scott) with little vetting, delegated mitigation work to him, and relied on a psychiatric expert (Dr. Earnest Miller). Scott produced minimal work product, did not obtain many records, and gave a weak, poorly received trial testimony.
- Dr. Miller identified several potential mitigation themes (dysfunctional family, exposure to domestic violence, father's murder, substance-abuse risk, personality disorder) but the defense failed to develop or present documentary and family-witness proof supporting those themes.
- At the habeas hearing substantial additional mitigation evidence was developed: detailed domestic violence, extreme corporal punishment, and abuse showing Walker had a markedly different childhood experience than his siblings — evidence that was available pretrial but not pursued or presented.
- The habeas court found counsel’s mitigation investigation and sentencing presentation constitutionally deficient and that the deficiencies were prejudicial; the Supreme Court of Georgia affirmed that judgment.
Issues
| Issue | Walker's Argument | Warden's Argument | Held |
|---|---|---|---|
| Whether trial counsel rendered constitutionally deficient performance by hiring an unvetted mitigation specialist, failing to supervise the investigation, and presenting a weak mitigation case | Counsel failed reasonable investigation and supervision; delegation to an unqualified specialist produced grossly inadequate preparation for sentencing | Counsel made strategic choices, retained a mitigation specialist, and conducted some investigation; reliance on specialist was reasonable | Court held counsel’s mitigation investigation and preparation were constitutionally deficient (unreasonable delegation, inadequate follow-up, poor presentation) |
| Whether presentation at sentencing (Scott and Dr. Miller testimony; failure to secure family testimony) was adequate | Presentation was sparse, inconsistent, and off-putting; counsel failed to secure pivotal family witnesses (mother) who would have provided substantial detail | Trial testimony and experts were sufficient; family reluctance limited available proof | Court held the mitigation presentation was inadequate and trial counsel failed to adequately advise and secure family witnesses; mother would have testified if properly asked |
| Whether counsel’s errors prejudiced Walker such that there is a reasonable probability of a different sentencing outcome | Omitted mitigation (detailed domestic violence, physical abuse, differential treatment vs siblings) would have meaningfully altered juror weighing of mitigation vs aggravation | Aggravating facts were strong; additional mitigation would not have created reasonable probability of life verdict | Court held cumulative prejudice from omitted mitigation created a reasonable probability the sentencing outcome would have differed (death sentence vacated) |
| Whether the habeas court improperly relied on ABA Guidelines in assessing counsel’s performance | N/A (issue raised by Warden) | Argued habeas court improperly “graded” counsel by ABA standards | Court rejected Warden’s complaint: habeas court applied objective Strickland reasonableness review (ABA guidelines were considered as part of prevailing professional norms) |
