(Portland, OR)  --  Multnomah County Chair Deborah Kafoury says she's launched an administrative investigation into accusations that Sheriff Dan Staton has created a work environment hostile to employees.  Kafoury made the announcement yesterday, a day after the union representing patrol deputies gave Staton a "no confidence" vote.  Matt Ferguson, president of the Multnomah County Deputy Sheriff's Association, says Staton uses fear and favoritism to lead the sheriff's office "ruthlessly and unpredictably."
