130 F.4th 493
5th Cir.2025Background
- Brittany Marlowe Holberg was sentenced to death in Texas in 1998 for the murder of A.B. Towery, Sr., following a jury trial where she claimed self-defense while the state argued she killed during a robbery.
- During pretrial detention, the prosecution repeatedly sought testimony against Holberg from jail inmates in exchange for deals; only Vickie Kirkpatrick, a paid confidential informant, provided incriminating testimony after being placed in Holberg's cell.
- Kirkpatrick's status as a paid police informant, her compensation for other cases, and the favorable treatment regarding her own pending charges were not disclosed to the defense, despite her being the state's only witness to Holberg's alleged confession and incriminating statements.
- After her conviction and death sentence, Holberg pursued state and federal habeas relief, arguing in part that the prosecution violated Brady v. Maryland by withholding impeachment evidence about Kirkpatrick's informant status.
- The federal district court denied relief, but the Fifth Circuit reversed, holding that the state’s failure to disclose Kirkpatrick’s informant role was material under Brady and undermined confidence in the conviction and death sentence.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Suppression of favorable evidence under Brady | State suppressed Kirkpatrick's role as a paid informant and her incentives to testify | Kirkpatrick was a paid informant only in unrelated matters; no formal deal and evidence was not material | State violated Brady; undisclosed impeachment evidence was material |
| Materiality of suppressed informant status to conviction | Kirkpatrick’s testimony was critical; impeachment would affect both guilt and sentencing | Overwhelming independent evidence of guilt; Kirkpatrick not a critical witness | Reasonable probability that result would differ if evidence disclosed |
| AEDPA deference to state court rejection of Brady claim | State court’s decision was unreasonable application of clearly established law | State court reasonably applied Brady; jury wouldn't have acquitted or spared Holberg regardless of impeachment | State court's denial was unreasonable under AEDPA; habeas relief warranted |
| Impact of suppressed evidence on sentencing phase | Kirkpatrick's testimony influenced finding of future dangerousness for death penalty | Punishment phase focused elsewhere; evidence of unremorse/violence came from other sources | Suppressed evidence was also material to sentencing, requiring new trial |
