Witness testimony corroboration permits proof of prior statements concerning the same fact when made contemporaneously or during competent investigation.

Corroboration of witness testimony permits proof of a witness's former statement concerning the same fact when made at or about the time of the occurrence, or before an authority legally competent to investigate that fact. The earlier statement may be proved in evidence to support the witness's later testimony, and its corroborative use requires both statements to relate to the same fact.
