Parishioners flooded St. Rose of Lima Church for services, interrupted briefly when someone phoned in a threat.
Over the weekend, the survivors and their families battled grief to share the stories of compassion and heroism of loved ones lost.
Victoria Soto, the 27-year-old teacher and daughter of a state worker, reportedly hid her students in a closet to save them. Emilie Parker, a charming 6-year-old, drew pictures and cards to comfort people who were sad. School Principal Dawn Hochsprung, 47, lunged at the shooter after he blasted a hole in a window to get in.
Many turned to the grim task of planning funerals.
The family of Noah Pozner, a 6-year-old victim, said services are scheduled for Monday.
Amid the mourning Sunday, an army of electricians, plumbers, painters and other volunteers descended on a shuttered middle school in the neighboring town of Monroe. They planned to reopen Chalk Hill school for Sandy Hook students starting on Wednesday, said Monroe Police Lieutenant Brian McCauley.
“They’re trying to restore as much of a sense of normalcy as possible. And normalcy comes with going to a safe and secure building,” McCauley said.
McCauley spoke Sunday as he watched scores of volunteers scrub floors, wipe windows and search for tables and chairs to accommodate small children. Police cordoned off the school, at the end of a long driveway, and will continue to guard it once school starts.
“We’re a small, New England town,” he said. “We work with our neighbors. Everybody pulls together.”
Connecticut Education Commissioner Stefan Pryor told the Associated Press on Sunday that it was ‘‘too soon to know’’ if the Sandy Hook school building will ever reopen.
In Massachusetts, some public schools will hold a moment of silence Monday as students return to class. Principals at Newton South High and Newton North High e-mailed announcements to the school communities over the weekend, assuring parents and students that security procedures were in place and offering tips on how to handle questions about the tragedy.
Boston and other school systems planned to increase police presence this week to reassure students and parents.
