Rule 807. Residual Exception
A statement not specifically covered by Rule
803 or
804 but having equivalent circumstantial guarantees of trustworthiness, is not excluded by the hearsay rule, if the court determines that
(B)
the statement is more probative on the point for which it is offered than any other evidence which the proponent can procure through reasonable efforts; and
(C)
the general purposes of these rules and the interests of justice will best be served by admission of the statement into evidence. However, a statement may not be admitted under this exception unless the proponent of it makes known to the adverse party sufficiently in advance of the trial or hearing to provide the adverse party with a fair opportunity to prepare to meet it, the proponent’s intention to offer the statement and the particulars of it, including the name and address of the declarant.
