Multnomah County has sworn in a new sheriff to replace one forced to resign. It's the second time in 16 months that's happened.

Twenty-year sheriff's office veteran Lt. Dan Staton took the oath as sheriff on Thursday.

Bob Skipper named Staton to replace him after the 70-year-old Skipper failed to get the police certification required to keep his job.

Last year, Skipper was sworn in as interim sheriff after Bernie Giusto resigned under pressure over ethics and management problems. Skipper then won election but didn't become certified within a year as required by state law.

Staton, 50, is certified and has worked in numerous areas within the sheriff's office, from internal affairs to river patrol to training.
