(Oregon City, OR) -- A Gladstone man who threatened to kill his former boss and other co-workers has been sentenced to 15 days in jail and 18 months' probation. Joshua Coughlin pleaded guilty to Disorderly Conduct. The Clackamas County District Attorney says Coughlin was fired from his job as a forklift operator last summer after he missed two days of work related to alcohol use. When a supervisor contacted Coughlin, he became erratic and aggressive. He later threatened to harm or kill certain employees. The company closed for two days due to the threats. In addition to jail time, he must perform 40 hours of community service.
