Twenty bright first graders with their entire lives ahead of them were gunned down on Dec. 14 at Sandy Hook Elementary School in Newtown, Conn. Along with the students, the lives of six school staffers, including a devoted teacher and a proud principal, were lost. Click through to see the victims at Sandy Hook Elementary School.
Noah Pozner and his twin sister celebrated their sixth birthdays on Nov. 20. His sister, Arielle, who was in another class, survived.
Pozner's uncle Alexis Haller told The Associated Press that he was "smart as a whip," gentle but with a rambunctious streak.
Haller told the AP that Pozner called Arielle his best friend.
"They were always playing together, they loved to do things together," Haller said. When his mother, a nurse, would tell him she loved him, he would answer, "Not as much as I love you, Mom."
Funeral services Pozner are planned for Monday.
Emilie Parker, the little girl with the blond hair and bright blue eyes, would have been one of the first to comfort her classmates at Sandy Hook Elementary School, had a gunman's bullets not claimed her life, her father said.
"My daughter Emilie would be one of the first ones to be standing and giving support to all the victims because that's the kind of kid she is," her father, Robbie Parker said as he fought back tears, telling the world about his "bright, creative and loving" daughter who was one of the 20 young victims in the Newtown, Conn., shooting.
"She always had something kind to say about anybody," her father said. "We find comfort reflecting on the incredible person Emilie was and how many lives she was able to touch."
Emilie was a budding artist who carried her markers and pencils everywhere. Her grandfather recently passed away and Emilie paid tribute to him by slipping a special card she had drawn into his casket, her father said.

Jack's funeral is scheduled to take place Monday.
Jack was a fan of New York Giants wide receiver Victor Cruz, who paid tribute to the 6-year-old during Sunday's game against the Atlanta Falcons.
Cruz honored Jack Sunday on his cleats, writing on them the words "Jack Pinto, My Hero."
"I also spoke to an older brother and he was distraught as well. I told him to stay strong and I was going to do whatever I can to honor him," Cruz said after the game. "He was fighting tears and could barely speak to me."
Cruz said he plans to give the gloves he wore during the game to the boy's family, and spend some time with them.
The family released a statement saying, Jack was an "inspiration to all those who knew him."
"Jack loved school, reading, wrestling, skiing and football. Most of all Jack loved to play with his friends and keep up with his big brother," said his family. "He had a wide smile that would simply light up the room and while we are all uncertain as to how we will ever cope without him, we choose to remember and celebrate his life. Not dwelling on the loss but instead on the gift that we were given and will forever cherish in our hearts forever."
Like most first graders, Jesse Lewis was excited for the holiday season. The 6-year-old, who was in Victoria Soto's class, couldn't wait to go to school on Friday because they were making gingerbread houses, and his father had planned to join them.
Victoria Soto, 27, one of the adult victims, loved being a teacher, her cousin, Jim Wiltsie, told ABC News' Chris Cuomo Friday. In fact, her first-grade students' safety was such a high priority that Soto reportedly lost her life protecting them.
"The family was informed that she was trying to shield, get her children into a closet and protect them from harm, and by doing that put herself between the gunman and the children," Wiltsie said. "And that's when she was tragically shot and killed.
"I'm very proud to have known Vicki," Wiltsie added. "Her life dream was to be a teacher. And her instincts kicked in when she saw there was harm coming to her students.
"It brings peace to know that Vicki was doing what she loved, protecting the children," he said. "And in our eyes, she is a hero."
"We are overwhelmed by the outpouring of love and support from so many people. Our daughter Grace was the love and light of our family. Words cannot adequately express our sense of loss."
As with so many, the ABC family has been touched directly by the tragedy in Sandy Hook.
One of the young victims, Catherine Hubbard, is the niece of an ABC News employee.
Here is a statement from the family:
"We are greatly saddened by the loss of our beautiful daughter, Catherine Violet and our thoughts and prayers are with the other families who have been affected by this tragedy.
"We appreciate the overwhelming support from our community that we have received over the past 24 hours.
"We also wish to express our gratitude for all of the emergency responders who responded to this tragic incident as well as the teachers and staff of Sandy Hook School. Our local police and fire departments and the other agencies who are working on this continuing investigation have been incredible.
"We also want to recognize outstanding work of The Connecticut State Police who have been supporting us from the very beginning of this ordeal and continue to provide unwavering support to our family.
"We have no further statement to make at this time and ask that we be afforded the opportunity to grieve with our friends and family.
"We ask that you continue to pray for us and the other families who have experienced loss in this tragedy.
"Jennifer and Matthew Hubbard"
Hochsprung became principal of Sandy Hook in recent years and by all accounts, was devoted to the students and teachers at her school.
"When we had our orientation, you could tell she loved her job," Brenda Lediski, a parent, told ABC News by phone.
Kristin Larson, a former PTA secretary, told the Boston Globe that Hochsprung was "always enthusiastic, always smiling, always game to do anything."
"When I saw her at the beginning of the school year, she was hugging everyone," Larson said.
The terrifying moment Hochsprung came into contact with the gunman were heard over the school intercom and may have saved lives.
It's not clear whether the intercom was turned on purposefully to alert the school's staff to the menace or whether the intercom was on for morning announcements.
Either way, it caught the initial moments of Adam Lanza's lethal fury and gave teachers and others life saving moments to lock their doors and try to hide their children.

"We will miss her terribly," Lauren's mother, Teresa Rousseau , told the Delaware County Times. "And will take comfort knowing that she had achieved that dream."
The 6-year-old was just learning the rosary and would lead the family in grace every night before dinner, the New Haven Register reported. Her favorite colors were pink and purple. She leaves behind a 3-year-old brother.
Her family released a statement describing Olivia as "creative" and a fan of craft projects and art class. She was a patient big sister to 3-year old Brayden and would lead Grace each evening at the dinner table, according to her father, Brian.

The family described Jessica as "a creative, beautiful little girl who loved playing with her little brothers, Travis and Shane.
"We cannot imagine our life without her. We are mourning her loss, sharing our beautiful memories we have of her, and trying to help her brother Travis understand why he can't play with his best friend," they said.
The 6-year-old, with her beaming smile, was the daughter of a jazz musician. She sang in a home video with her brother, who was also at Sandy Hook Elementary School during the massacre.
The girl's grandmother, Elba Marquez, told The Associated Press the family moved to Connecticut just two months ago, drawn from Canada, in part, by Sandy Hook's sterling reputation. The grandmother's brother, Jorge Marquez, is mayor of a Puerto Rican town.
Charlotte's parents, Joann and Joel, had lived in Newtown for four or five years, Joann's brother John Hagen, of Nisswa, Minn., told Newsday.
