State v. Capone, 426 P.3d 469

Background

In April 2010 Rachael Anderson disappeared after visiting her estranged husband, Charles Capone; her white Yukon later was found with her purse inside. No body was recovered.
David Stone, a cellmate, testified he saw Capone strangling Anderson, left to get a tarp, and returned to find her dead; Stone testified he and Capone wrapped the body and dumped it from a bridge. Stone later pleaded guilty to related charges and agreed to testify against Capone.
Capone made inculpatory statements to two other cellmates (Brent Glass and Joshua Voss) while jailed on an unrelated federal firearms charge, including remarks that Anderson was "pushing up daisies."
Capone was tried and convicted of first-degree murder, failure to notify coroner or law enforcement of death, and conspiracy to commit that failure; Stone was conceded to be an accomplice for the non-homicide counts but not for the murder count.
Post-verdict, Capone sought a new trial based on a statement by Stone to another cellmate (Tyler Byer) that Anderson was not in the river; the district court denied the motion.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Stone was an accomplice to the murder	State: Stone was a bystander, not an accomplice to murder	Capone: Stone aided by fetching a tarp while Anderson was alive, making him an accomplice	Court: Stone was not an accomplice to the murder (no evidence he aided, abetted, or shared intent)
Sufficiency of corroboration for accomplice testimony (failure-to-notify and conspiracy counts)	State: Evidence (tarp purchase, Capone’s statements, actions) sufficiently corroborates Stone	Capone: Record contains contradictions and insufficient independent corroboration	Court: Corroboration sufficient to connect Capone to those crimes; convictions upheld
Failure to give accomplice corroboration jury instruction	Capone: Omission was error (not objected to at trial)	State: Any error harmless because corroboration existed	Court: Failure to give instruction harmless error given existing corroboration
Admissibility of 404(b) evidence (prior strangulation attempt and firearms disqualification)	State: Evidence relevant to motive and other non-propensity purposes	Capone: Evidence inadmissible propensity evidence and/or outside scope of motion in limine rulings	Court: Admission of prior strangulation was error but harmless; objection to firearms evidence was not preserved for appeal
Exclusion of Glass and Voss’s burglary convictions for impeachment	Capone: Convictions were relevant to credibility under I.R.E. 609	State: Not relevant to credibility; motion in limine sustained	Court: Exclusion was error (burglary can bear on credibility) but harmless in context of other evidence
Motion for new trial based on Stone’s later statement (Byer)	Capone: Byer’s testimony that Stone said the body was not in the river is newly discovered and material	State: Statement is hearsay/impeachment-only; would not probably produce acquittal	Court: Denial affirmed — evidence was impeachment/hearsay, not likely to produce acquittal, and not admissible as party-opponent admission
