The Basalt Police Department was stretched thin over the past 10 days filling all patrol shifts after 75 percent of its officers were in quarantine for possible exposure to COVID-19. Only one officer has tested positive for the virus but others had to take precautions because of possible exposure, Police Chief Greg Knot said Monday. “We had one officer test positive for COVID,” he said. “Four other officers were deemed to be in close contact with him at work.” The problem arose Friday, Jan. 8, when there was crossover time between officers finishing the weekday shift and those reporting for weekend shifts. The officers were in the police station in Basalt at the same time for about one hour. An officer became ill the next day and tested positive for COVID-19.
