Rule 804. Hearsay exceptions: declarant unavailable.

(a) Definition of unavailability. Unavailability as a witness includes situations in which the declarant:

(1) is exempted by ruling of the court on the ground of privilege from testifying concerning the subject matter of the declarant's statement; or

(2) persists in refusing to testify concerning the subject matter of the declarant's statement despite an order of the court to do so; or

(3) testifies to a lack of memory of the subject matter of the declarant's statement; or

(4) is unable to be present or to testify at the hearing because of death or then existing physical or mental illness or infirmity; or

(5) is absent from the hearing and the proponent of the declarant's statement has been unable to procure the declarant's attendance by process or other reasonable means.

A declarant is not unavailable as a witness if exemption, refusal, claim of lack of memory, inability, or absence is due to the procurement or wrongdoing of the proponent of a statement for the purpose of preventing the witness from attending or testifying.

(b) Hearsay exceptions. The following are not excluded by the hearsay rule if the declarant is unavailable as a witness:

(1) Former testimony. Testimony given as a witness at another hearing of the same or a different proceeding, or in a deposition taken in compliance with law in the course of the same or another proceeding, (A) in civil actions and proceedings, at the instance of or against a party with an opportunity to develop the testimony by direct, cross, or redirect examination, with motive and interest similar to those of the party against whom now offered; and (B) in criminal actions and proceedings, if the party against whom the testimony is now offered had an opportunity and similar motive to develop the testimony by direct, cross, and redirect examination.

(2) Statement under belief of impending death. A statement made by a declarant while believing that the declarant's death was imminent, concerning the cause or circumstance of what the declarant believed to be impending death.

(3) Statement against interest. A statement which was at the time of its making so far contrary to the declarant's pecuniary or proprietary interest, or so far tended to subject the declarant to civil or criminal liability, or to render invalid a claim by the declarant against another or to make the declarant an object of hatred, ridicule, or disgrace, that a reasonable person in the declarant's position would not have made the statement unless the declarant believed it to be true. A statement tending to expose the declarant to criminal liability and offered to exculpate the accused is not admissible unless corroborating circumstances clearly indicate the trustworthiness of the statement.

(4) Statement of personal or family history.

(A) A statement concerning the declarant's own birth, adoption, marriage, divorce or dissolution of marriage, legitimacy, relationship by blood, or family history, even though the declarant had no means of acquiring the personal knowledge of the matter stated; or

(B) a statement concerning the foregoing matters, and death also, of another person, if the declarant was related to the other by blood, adoption or marriage or was so intimately associated with the other's family as to be likely to have accurate information concerning the matter declared.

(5) Other exceptions. A statement not specifically covered by any of the foregoing exceptions but having comparable circumstantial guarantees of trustworthiness.
