Citrus County Deputy Glenn Ryan, 28, who was charged with drunken driving over the weekend in Seminole County, has resigned. Ryan had been placed on administrative leave with pay after his arrest Sunday, pending an investigation. The Sheriff's Office said the investigation continues because, if the charge is sustained, findings must be submitted to the Florida Department of Law Enforcement Criminal Justice Standards and Training Commission. Ryan, an officer for four years, was found sleeping in his car in the middle of the road Sunday outside Casselberry. Ryan refused a breath test after his arrest.
