Newborn got a new mayor Monday, but the city might need another one sooner than expected. Mark Vandervoet was sworn in as acting mayor of Newborn Monday to replace Roger Sheridan, who died in December, but Vandervoet informed the council he had reached an agreement to sell his Newborn house earlier Monday. Vandervoet said he didn’t have plans to sell his home at this time, but a buyer reached out to the Vandervoets and matched the asking price.
