Don Knight, file | The Herald Bulletin ANDERSON — Almost 50% of the inmates at the Madison County Jail are either in isolation or quarantine because of the coronavirus pandemic. Of the 249 inmates at the jail Tuesday, 51 were in isolation and 73 in quarantine for 14 days, according to Sheriff Scott Mellinger. “We are at a very critical stage in terms of space,” he said. Mellinger said two trusties tested positive for the coronavirus, which means all 14 trusties are in isolation and unable to work in the kitchen or clean the jail.
