In State v. Mecier, 138 Vt. 149, 152, 412 A.2d 291, 294 (1980), the Court upheld the authentication of tapes made by a sheriff of telephone conversations with the defendant while he was barricaded in his house after shooting his wife and daughter. At trial, the sheriff testified that he was familiar with the defendant's voice and that the tapes were continuous despite several gaps within. The Court held that under these circumstances the tapes were identified with "reasonable certainty." Id. at 153, 412 A.2d at 294.
