With the same desks, artwork, and backpacks from Sandy Hook Elementary School, classes resumed for the students at a nearby elementary school, three weeks after a gunman killed 20 students and six children. Workers spent much of the past three weeks transforming the former Chalk Hill middle school—which had closed due to declining enrollment—into an elementary school, and parents and students were allowed to come tour the school on Wednesday. But despite the best effort to keep things the same, there were some major differences: police cars were parked at the local high school, and retired principal Donna Page returned to replace Dawn Hobsprung, who was killed when she tried to stop Adam Lanza from the rampage.
