In February and March of 2005, Ezial Avery was in jail awaiting trial on charges that he kidnapped and sexually assaulted his wife. At that time, Avery was subject to a court order which prohibited him from contacting his wife. In spite of the court order, Avery telephoned his wife from the jail on numerous occasions and tried to persuade her to not testify against him in front of the grand jury.
The Department of Corrections routinely records inmates' telephone calls. When the police learned that Avery had been contacting his wife, they obtained a warrant that authorized them to obtain and listen to the recordings of the telephone calls Avery had made to his wife. Based on these telephone calls, a grand jury indicted Avery on one count of first-degree tampering with a witness (for inducing or attempting to induce a witness to testify falsely or offer misleading testimony). Twelve counts of unlawful contact in the first degree (for contacting V.Q. in violation of the court order) were added by information.
Avery moved to suppress the telephone recordings.

Wolverton granted Avery's motion to suppress. The State petitioned for review. We granted the State's petition, and we now reverse the superior court's ruling.

As we have already noted, the Department of Corrections routinely records inmates' telephone calls (except those to an attorney or the Ombudsman). Signs posted above the prisoner telephones warn that " telephone calls may be monitored and recorded." In addition, each prisoner phone call is preceded ...
