831 F.3d 345
5th Cir.2016Background
- In 1986 Segundo raped and murdered an 11-year-old; his DNA matched in 2005. He was convicted and sentenced to death; Texas courts affirmed.
- At trial defense experts tested Segundo’s IQ (around 75) and concluded he was not intellectually disabled; state habeas experts reached similar conclusions after an evidentiary hearing.
- Segundo raised an Atkins claim (intellectual disability bars execution) in state habeas but did not frame an ineffective-assistance-of-trial-counsel (IATC) claim there; the Texas Court of Criminal Appeals denied relief.
- In federal habeas proceedings Segundo sought to invoke Martinez v. Ryan / Trevino to excuse his state-court default, alleging trial counsel failed to investigate adaptive‑behavior deficits and thus was ineffective; he submitted a new expert affidavit (Dr. Greenspan).
- The district court denied an evidentiary hearing, found Segundo’s IATC claim not substantial under Martinez/Strickland, and denied a COA; the Fifth Circuit likewise denied a COA, holding Martinez does not automatically entitle petitioners to federal fact‑finding and that reasonable counsel relied on experts and investigators.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether Martinez/Trevino allow federal evidentiary hearing to develop IATC claim | Segundo: Martinez/Trevino excuse procedural default and require fact‑finding to show cause and prejudice | State: Martinez permits merits review only; no automatic right to federal evidentiary hearing | Court: Martinez does not mandate an evidentiary hearing; district court did not abuse discretion in denying one |
| Whether trial counsel was ineffective for failing to investigate adaptive‑behavior/social history | Segundo: Counsel failed to provide experts with social history, so experts missed evidence of intellectual disability | State: Counsel retained mitigation investigator, fact investigator, and two mental‑health experts who evaluated records and family; no expert said they lacked info | Court: Counsel performed reasonable investigation and properly relied on expert evaluations; no deficient performance shown |
| Whether Segundo showed prejudice under Strickland (reasonable probability of different outcome) | Segundo: With fuller investigation and alternative expert analysis, a diagnosis of intellectual disability was likely and would have affected sentencing | State: Existing expert evaluations and state‑court factfinding show no intellectual disability; later expert disagreement insufficient | Court: No substantial likelihood of a different result; prejudice not shown |
| Whether Martinez excuse applies so federal merits review is available | Segundo: Martinez applies because state habeas counsel failed to present IATC claim | State: Even if Martinez framework considered, the underlying IATC claim is meritless so Martinez inapplicable | Court: Martinez inapplicable because IATC claim is not substantial; COA denied |
