On Friday, the sheriff’s office announced that 26 inmates with less than 60 days left to serve were being released from county jails. The court issued the order to reduce the county jail population and minimize prisoner and staff exposure to the coronavirus, sheriff’s office spokeswoman Nancy Crowley said.

The sheriff’s office said it is operating under a COVID-19 response and action plan for its jails to prevent the spread of the novel virus. Some actions include monitoring, rapidly identifying and separating any person who is showing symptoms of coronavirus.
