NEWTOWN, Conn. -- Opening a long and almost unbearable procession of grief, Newtown began laying its dead to rest Monday, holding funerals for two 6-year-old boys -- one a football fan who was buried in a New York Giants jersey and one whose twin sister survived the school shooting rampage.
Two funeral homes filled with mourners for Noah Pozner and Jack Pinto, the first of the 20 children killed in last week's massacre to receive funerals. The gunman also killed six adults at Sandy Hook Elementary, and his mother in her home, before committing suicide.
A rabbi presided at Noah's service, and in keeping with Jewish tradition, the boy was laid to rest in a simple brown wooden casket with a Star of David on it.
"If Noah had not been taken from us, he would have become a great man. He would been a wonderful husband and a loving father," Noah's uncle, Alexis Haller, told mourners, according to remarks he provided to The Associated Press. Both services were closed to the news media.
Noah's twin, Arielle, who was assigned to a different classroom, survived the killing frenzy by 20-year-old Adam Lanza, an attack so horrifying that authorities could not say three days later whether the school would ever reopen.
Newtown will face many more funerals over the next few days, just as other towns are getting ready for the holidays.
"I feel like we have to get back to normal, but I don't know if there is normal anymore," said Kim Camputo, mother of two children, 5 and 10, who attend a different school.
Beyond Newtown, parents nervously sent their children back to class in a country deeply shaken by the attack, and in a measure of how the tragedy has put people on edge, schools were locked down in at least four places.
As investigators worked to figure out what drove Lanza to lash out with such fury -- and why he singled out the school -- federal agents said he had fired guns at shooting ranges over the past several years but there was no evidence he did so recently as practice for the rampage.
At Jack's Christian service, hymns rang out from inside the funeral home, where the boy lay in an open casket in the Giants' star wide receiver Victor Cruz's No. 80 jersey. Jack was among the youngest members of a youth wrestling association in Newtown, and dozens of little boys turned up at the service in gray Newtown Wrestling T-shirts.
Ten-year-old Luke Wellman remembered a boy who loved football and wrestling and worshipped Cruz, who played in Sunday's game with "Jack Pinto ‘My Hero"' written on one of his cleats.
Luke said: "I'm here to support my teammate and friend."
A mourner, Gwendolyn Glover, said the service carried a message of comfort and protection, particularly for other children. "The message was: You're secure now. The worst is over," she said.
At Noah's funeral, the boy was described a smart, funny and mischievous child who loved animals, Mario Brothers video games and tacos.
"I will miss your forceful and purposeful little steps stomping through our house. I will miss your perpetual smile, the twinkle in your dark blue eyes, framed by eyelashes that would be the envy of any lady in this room," his mother, Veronique Pozner, told mourners, according to Haller.
"Most of all, I will miss your visions of your future. You wanted to be a doctor, a soldier, a taco factory manager. It was your favorite food, and no doubt you wanted to ensure that the world kept producing tacos," she said, evoking laughter.
She closed by saying: "Momma loves you, little man."
Around the country, school systems asked police departments to increase patrols Monday and sent messages to parents outlining safety procedures. Teachers steeled themselves for their students' questions and fears.
Anxiety ran high enough in Ridgefield, about 20 miles from Newtown, that officials ordered a lockdown at schools after a person deemed suspicious was seen at a train station. Two schools were locked down in South Burlington, Vt., because of an unspecified threat.
Three schools in the Tampa, Fla., area did the same after a bullet was found on the floor of a school bus, and a New Hampshire high school went into emergency mode after an administrator heard a loud bang. A police search found nothing suspicious.
