Sgt. Darrell O’Neill, 58, a 30-year veteran of the force, had been placed on paid administrative leave following his arrest by Everett police on June 25. He was held for conspiracy to promote prostitution and official misconduct.
O’Neill was accused of tipping off bikini baristas who may have been engaged in prostitution to undercover police operations.
Any criminal charges as a result of that investigation will be filed by the Snohomish County prosecutor’s office, the sheriff’s office said, adding that it was ending its internal investigation of O’Neill with his resignation.
The sheriff’s office spokeswoman said O’Neill will keep his pension by resigning.
