NEWTOWN, Conn. — A grief-stricken Newtown today began laying to rest the littlest victims of the school massacre, starting with two 6-year-old boys — one of them a big New York Giants fan, the other described as a whip-smart youngster whose twin sister survived the rampage.

Family, friends and townspeople streamed to two funeral homes to say goodbye to Jack Pinto, who might be buried in wide receiver Victor Cruz’s jersey, and Noah Pozner, who liked to figure out how things worked mechanically.

In front of the funeral home where relatives mourned Noah, well-wishers placed two teddy bears, a bouquet of white flowers and a single red rose at the base of an old maple tree. At Jack’s service, hymns rang out from inside the funeral home.

“He was just a really lively, smart kid,” said Noah’s uncle Alexis Haller, of Woodinville, Wash. “He would have become a great man, I think. He would have grown up to be a great dad.”

Noah’s twin sister, Arielle, who was assigned to a different classroom, survived the killing frenzy by 20-year-old Adam Lanza that left 20 children and six adults dead last week at Sandy Hook Elementary School in an attack so horrifying that authorities could not when or even if the school would reopen.
