MILLEN - Millen's skyline was an orange cloud of smoke Monday night as the old primary school burned to the ground in what officials believe to be a possible arson. The first calls from witnesses came in around 8 p.m., Mayor King Rocker said. The school was situated downtown Millen between Millen Baptist and Millen Methodist churches.Board of Education Chairman Carroll Gay said it is almost certainly a case of arson, as witnesses saw people leaving the scene 10 to 15 minutes before seeing the building blaze up in more than one location.
