If a witness is killed, or dies, before formally testifying at a criminal trial in what manner, if any, can his relevant statements be admitted or used against a defendant?

For example, if sworn testimony has been recorded can that be admitted? What about unsworn written testimony? What about hearsay?

    I'm not an expert, but I suspect that different jurisdictions have different rules to cover this sort of situation. So there are probably many possible answers. (Incidentally, killing a witness doesn't seem like a viable legal strategy.) Commented May 26, 2015 at 21:28

    @JonEricson The question is essentially that if a witness is killed, does that automatically suppress or exclude their testimony under the Hearsay rules under the Federal Rules of Evidence, or is it cover under one of the Prior Statements of a Witness exceptions? Seems perfectly answerable. Commented May 26, 2015 at 21:42

    I suspect most questions on this site will have jurisdictional differences, and may in many cases not even be settled law. Let's leave these open for now. There will be common law customs that can inform many, and those who want to provide jurisdictional nuances will only enrich the value of the site.

    @RobertCartaino: That's probably a good way to answer for criminal trials in the US. But I suspect those rules don't apply in, say, China. (See also my answer to How do we handle localization of questions/answers?.) Commented May 26, 2015 at 22:03

    @RobertCartaino You are assuming this case is one in which US law would apply, but that doesn't seem obvious to me from the question.

There are instances when the testimony may still be admitted. For example, a deposition may be admitted at trial either for impeaching or when a witness cannot attend, which involves the circumstance of death (FRCP 32(a)(4)(a)).

Additionally, regarding hearsay, there are numerous exceptions. My Evidence professor said in class "If you cannot find a way to get evidence around a hearsay objection, you are not trying hard enough." One such hearsay exception states in the committee notes:

Accordingly, the committee has amended rule 803(8) to refer to the provision of [proposed] rule 804(b)(5) [deleted], which allows the admission of such reports, records or other statements where the police officer or other law enforcement officer is unavailable because of death, then existing physical or mental illness or infirmity, or not being successfully subject to legal process.

    It should be noted that the FRCP applies to Civil Procedure, not Criminal Procedure. If you killed a witness, they could probably get you for murder or at least witness tampering, both of which would generate quantities of evidence that would be allowable for those charges.

    Rule 804 also seems to apply. So it actually sounds like in practice it is quite feasible to admit the statements of a witness who is unavailable, including due to death. Therefore, contrary to the common Hollywood plot device, a high-profile high-risk witness is, in practice, likely to have his testimony recorded at the earliest possible moment, at which point suppression would require killing not only the witness but also everyone who heard his testimony and all physical recordings of that testimony.

    @feetwet: In particular see Rule 804 (b) (6), which says that a hearsay exception applies to "A statement offered against a party that wrongfully caused — or acquiesced in wrongfully causing — the declarant’s unavailability as a witness, and did so intending that result." Killing a witness would certainly "wrongfully cause their unavailability". Commented Sep 30, 2016 at 12:03

    Rule 804 does not really contradict the Hollywood plot device. If the prosecution can establish that the defendant was complicit in the murder of the witness (so as to attract the operation of rule 804(b)(6)), then the original charge is probably the least of the defendant's concerns. If the prosecution cannot prove that the defendant was involved in the witness's death, then rule 804 is unlikely to render the hearsay evidence of the deceased witness admissible.

As observed in another answer, evidence that a deceased person said something is prima facie hearsay and can be admitted under the various hearsay exceptions. Many jurisdictions have statutory exceptions for witnesses who die after making a formal statement of some kind. The accused may have the opportunity to object to such evidence on the ground that he or she has been unfairly deprived of the opportunity to cross-examine the witness. However, there are also some common law exceptions.

The following exceptions are detailed in section 1 of chapter 17 of Cross on Evidence: 'The Rule against Hearsay: Principal Exceptions at Common Law: Statements of Deceased Persons.' This is an Australian textbook, but the principles apply in any jurisdiction where the common law has not been supplanted by statute or local case law. (Because the source is Australian, it is worth adding the caveat that the common law has been replaced in most Australian jurisdictions by the Uniform Evidence Acts.)

  • Dying declarations: evidence that a deceased person said something under a 'settled hopeless expectation of death' is admissible in a trial for that person's murder or manslaughter. This rule is based on the scientifically dubious proposition that 'when the party is at the point of death, and when every hope of this world is gone: when every motive to falsehood is silenced, and the mind is induced by the most powerful considerations to speak the truth; a situation so solemn, and so awful, is considered by law as creating an obligation equal to that which is imposed by a positive oath administered in a Court of Justice': R v Woodcock (1789) 168 ER 352, 353. This exception has its own Wikipedia article. It is reproduced in many evidence statutes, including the (US) Federal Rules of Evidence, and remains significant today. One famous example of the use of this exception in Australia occurred in the trial of Bandali Debs and Jason Roberts for the 1998 Silk–Miller police murders. A significant piece of evidence against Roberts was the dying declaration of the murdered police officer Miller that there had been two offenders: see R v Debs & Roberts [2005] VSCA 66 [159].

  • Declarations in the course of duty: evidence that a deceased witness recorded or reported something that it was his or her duty to report is admissible, provided the record or report was roughly contemporaneous and the witness had no motive to misrepresent the facts. In R v McGuire (1985) 81 Cr App R 323, the appellant had been convicted of arson after a trial in which the judge had admitted evidence of a scientific officer's report on the fire. The officer died before the trial. The Court of Appeal confirmed that the trial judge had been correct to admit the report so far as it dealt with the facts, and correct to exclude it so far as it offered an expert opinion – though another expert could have given an opinion on the basis of the facts in the report.

  • Declarations against interest: evidence that a deceased witness said or wrote something which they knew to be against their own pecuniary or proprietary interest is admissible. This exception is of limited use in a criminal trial, since it doesn't extend to admissions against penal interest, but it is still applicable. For example, in R v Rogers [1995] 1 Cr App R 374, the exception was accepted to be applicable in principle in a criminal trial for possession of heroin, but the Court of Appeal found that the trial judge correctly excluded evidence that a deceased person had admitted that the heroin belonged to him and other people were 'after him for the money for the heroin.'

  • Declarations as to public or general rights: an oral or written declaration by a deceased person concerning the existence of such a right is admissible provided it was made before a dispute had arisen. This rather obscure exception is rarely used in criminal cases. It was commonly used in disputes over land before the establishment of land registration systems. However, I was able to find one criminal case concerning a prosecution for obstructing a highway in Middlesex by building houses and buildings on it. In R v Berger [1894] 1 QB 823, a divisional court of the Queen's Bench Division granted a new trial on the basis that the trial judge had been wrong to admit a 'map attached to an inclosure award made in 1814' as evidence that the land in question was part of the highway.

Cross on Evidence identifies three other exceptions which are generally relevant only to succession cases: declarations as to pedigree (ie. ancestry), post-testamentary declarations of testators concerning the contents of their wills, and extra-testamentary statements of testators as to disinheritance. I have ignored these exceptions, since succession cases fall into a special category where the intentions of a deceased person tend to be the central issue.

The rationale of the exceptions described above is that for one reason or another, the statement was made in circumstances that (supposedly) make it inherently reliable. They are not intended to discourage accused persons from murdering witnesses. Many commentators have observed that admitting hearsay evidence only when it falls into an arbitrary and closed set of categories of supposedly reliable hearsay utterances is confusing and illogical, hence the prevalence of evidence statutes in the modern era. For example, the authors of Morgan and Maguire, 'Looking Backward and Forward at Evidence' (1937) 50(6) Harvard Law Review 909, 921 said:

In short, a picture of the hearsay rule with its exceptions would resemble an old-fashioned crazy quilt made of patches cut from a group of paintings by cubists, futurists and surrealists.

  • While the motivation underlying the "dying declaration" exception may be debatable, I'm not sure how you'd go about proving it or disproving it "scientifically". At least, not in a way that an IRB would allow. Commented Nov 30, 2017 at 16:20

    If the defendant was the cause of the death of the hearsay declarant, the defense might also be estopped from asserting a hearsay objection in that circumstance even if it was not within any of the express hearsay exceptions. Also in many jurisdiction (such as the U.K.) there is a hearsay blanket exception for all circumstances when the declarant is unavailable. And, the hearsay rule does not exist in civil law countries.

I will address the issue if the witness is "killed or dies" and presume this relates to a criminal case. I will not simply cut and paste from internet resources, but will provide some material I have used in drafting motions for counsel in criminal cases.

The right to confront one's accusers is a concept that dates back to Roman times. See Coy v. Iowa, 487 U.S. 1012, 1015 , 108 S.Ct. 2798 , 101 L.Ed.2d 857 (1988). In Crawford v. Washington, 541 U.S. 36 (2004). The Court radically revamped the analysis that applies to confrontation clause objections. Crawford overruled the reliability test for confrontation clause objections and set in place a new, stricter standard for admission of hearsay statements under the confrontation clause. Crawford held that testimonial statements by declarants who do not appear at trial may not be admitted unless the declarant is unavailable and the defendant had a prior opportunity to cross-examine the declarant.

However, in Crawford, 541 U.S. at 59 n.9, the Court found “The [Confrontation] Clause . . . does not bar the use of testimonial statements for purposes other than establishing the truth of the matter asserted.”

If you have access to Westlaw, for great motions, see 4 Cal. Crim. Practice: Motions, Jury Instr. & Sent. § 48:9 (4th ed.)

As to the second part of your question briefly, unless the witness can be cross-examined, then the statements cannot be admitted. However, if the defendant is responsible for killing the witness (and the state can prove it), he has more problems than he could ever wish for and cannot benefit from killing the witness. To address this issue requires a lot of time, so may address it later.
