BEND, OR -- Deschutes County Sheriff Shane Nelson announced Friday he has placed a supervisor on paid administrative leave pending an investigation into how department funds were used.

A county auditor recommended additional internal analysis into the money used for investigative purposes, during the transition between retiring Sheriff Larry Blanton and incoming Sheriff Nelson.

Nelson says the internal audit, which is ongoing, found issues relating to the funds. Preliminary findings prompted a broader look and the DCSO supervisor was placed on leave in order to preserve the integrity of the investigation. 

The Sheriff's Office is working with Bend Police, Oregon State Police, the Deschutes County District Attorney, the U.S. Attorney's Office and the FBI. Deschutes County D.A. John Hummel released a statement saying, "Deschutes County residents should be confident that when a misdeed occurs in local government, local officials will root it out and right the wrong."
