SPOKANE, Wash. -

The corrections officer who fired his service weapon while attempting to prevent a prisoner from escaping custody at Deaconess Hospital has been identified by Spokane County Detention Services.

Sandy Rief has served as a corrections officer for the last five years. During that time he has received two letters of appreciation, both in 2012, for his actions in helping two different individuals who were suicidal.

Prior to becoming a corrections officer, Rief served in the Air Force for 20 years.

Rief discharged his weapon while attempting to apprehend Cameron Trevino, a prisoner who escaped custody while receiving medical treatment at the hospital. Rief only fired his weapon once, no one was hit, and Trevino was taken back into custody.

Rief is currently on paid administrative leave, which is standard in the wake of any officer-involved shooting. The Spokane Investigative Regional Response Team's investigation into the incident is ongoing.
