  Tier two

  • Any crimes not listed above are tier two crimes. Tier two patients are under the jurisdiction of the State Hospital Review Panel (SHRP) while receiving treatment at Oregon State Hospital. Once a tier two patient is conditionally released, PSRB assumes jurisdiction over the individual and will continue to monitor and supervise the person in the community for the remainder of his or her term of commitment.
