272 P.3d 10
Kan.2012Background
- Carapezza and Hughes were convicted of felony murder and related offenses in Kansas, with appellate remands for new trials.
- The district court suppressed evidence that was tied to the defendants’ immunized inquisitions, ruling it derived from immunized testimony.
- The State appealed interlocutorily, challenging the district court’s burden, and contending no improper use of immunized statements occurred.
- A Kastigar hearing was conducted to determine whether any proposed evidence in the retrial was independently sourced.
- The district court excluded the testimony of several witnesses and permitted 38 others, finding independent sources for their testimony was lacking for the excluded ones.
- The Kansas Supreme Court affirmed, holding the State failed to prove all evidence used in retrials could be independently sourced from collateral materials.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Burden of proof for derivative use | State contends Kastigar preponderance applies to indirect use. | Carapezza/Hughes contend Kansas requires clear and convincing proof for derivative use. | State burden met only with independent sources; court affirms district court’s approach. |
| Prosecutor/officer participation after exposure | Exposure to immunized statements does not taint ongoing prosecution. | Prosecutors/officers cannot rely on immunized statements in trial strategy. | Prosecutors and investigators exposed to immunized statements must refrain from derivative use; district court's restrictions affirmed. |
| Derivation of evidence for lay witnesses | Some lay witnesses could be used if not tainted by immunized testimony. | That taint was pervasive; no independent source established. | District court’s negative Kastigar findings regarding lay witnesses affirmed; no new contrary finding. |
