Updated at 6 p.m. ET Tuesday: The youngest victim had a twin at the school. The oldest was the school psychologist. Another was the child of a jazz saxophonist. Among the 28 who died in the shooting in Newtown, Conn., were six teachers -- all women -- and 20 children, ages 6 and 7.

The two others who died were the gunman and his mother.   

Of the children, eight were boys and 12 were girls.

ADULTS

Dawn Hochsprung, 47, Sandy Hook Elementary principal
When shots rang out Friday at Sandy Hook Elementary School in Connecticut, Hochsprung ran from a room where she was meeting with a parent and other staff members, school occupational therapist Diane Day told the Wall Street Journal.

She never returned.

Hochsprung, 47, has been described as fun and lighthearted, someone who maintained an active Twitter feed that noted successes and various events at school.

“Sandy Hook hosted district admins for instructional rounds today,” she tweeted on Nov. 29. “Amazing visit showcased deep learning!” 

Last week, she tweeted an image of fourth-grade students rehearsing for their winter concert. Days before that, an image of kindergartners exchanging play money at their makeshift grocery store.

“She was not the kind of principal I remembered as a kid,” Diane Licata, the mother of a first- and second-grader at Sandy Hook, told The New York Times. “She really reached out to the students and made them feel comfortable with her.”

She received her bachelor's degree in special education from Central Connecticut State University and her master's degree in education from Southern Connecticut State University. She was currently enrolled at Russell Sage College in Troy, N.Y., pursuing her Ph.D.

Hoschsprung was married with a high-school age son, according to the Wall Street Journal.

She viewed her school as a model for safety and learning, telling The Newtown Bee in 2010: “I don’t think you could find a more positive place to bring students to every day.”

Officials said she died while lunging along with the school psychologist at the gunman in an attempt to overpower him, The Associated Press reported.

Mary Sherlach, 56, school psychologist
Mary Sherlach had worked at Sandy Hook Elementary since 1994 and was known as a fixture at the school, according to the Connecticut Post.

Mary Sherlach, 56

She was the wife of Bill Sherlach, a financial consultant, and mother to two adult daughters, Maura and Katie. The Sherlaches were looking forward to retirement, which they had planned to spend on Owasco Lake, one of New York's Finger Lakes, Newtown Patch reported.

Eric Schwartz, Sherlach’s son-in-law, told the Connecticut Post that he and his wife immediately drove to Connecticut when they heard on the news that the school psychologist had been killed. 

Officials said Sherlach died while running with the principal toward the shooter. 

Schwartz described his mother-in-law as sharp, opinionated and an avid Miami Dolphins fan. She had planned to leave work early on Friday, he said, but never had the chance. 

As the news trickled out about the shooting, Schwartz told Patch: “It was a really helpless feeling. For about an hour, you try to say, ‘They got it wrong, they got it wrong.’”

"Mary felt like she was doing God's work, working with the children," he told NBCConnecticut.com.

Victoria Soto, 27, first-grade teacher
As the shooter entered Room 10, a first-grade classroom, teacher Vicki Leigh Soto tried to shield her students, her cousin Jim Wiltsie told the Wall Street Journal.

Victoria Soto, 27.

"That is how she was found. Huddled with her children," Wiltsie said.

Soto had taught for five years and was known by students as silly and loving. “She put those children first. That’s all she ever talked about,” a friend, Andrea Crowell, told The Associated Press. “She wanted to do her best for them, to teach them something new every day.”

On her teacher's bio, Soto wrote: "In my free time I love to spend time with black lab Roxie. I love spending time with my brother, sisters and cousins. I love to spend time reading books on the beach soaking up the sun.  I also love flamingos and the New York Yankees."  

Anne Marie Murphy, 52, special education teacher
Murphy, the sixth of seven children, was described by her 86-year-old father, Hugh McGowan, as “witty” and “hardworking,” according to New York Newsday.

Her mother, Alice McGowan, 86, described her as “a good soul.” She told Newsday that when she got the news, she grabbed her rosary and cried.

Authorities told the couple their daughter helped shield some of her students from the rain of bullets. 

“A first responder said she was a hero,” Murphy's father said. 

"You don't expect your daughter to be murdered. That's sort of a shocker. It happens on TV. It happens elsewhere," he added.

Woody Thompson, a neighbor of the Murphy family in Connecticut, said she and her husband were level-headed parents who allowed their four children to play one sport per season.

“They didn’t buy into some of the craziness and the hype of big-time organized youth sports,” Thompson told NBC News.  

Lauren Gabrielle Rousseau, 30, permanent substitute teacher
Rousseau was having "the best year of her life," her mother, Teresa Rousseau said, according to The Danbury News-Times, where she is a copyeditor.

Lauren Rousseau

Lauren had a boyfriend, Tony Lusardi III, the News-Times reported. After years of substitute teaching, she landed a permanent substitute teaching position at Sandy Hook. 

She grew up in Danbury and lived with her mother and her mother’s partner.

On Friday night, Rousseau had planned to see a movie, "The Hobbit," according to the News-Times. In preparation, she had made cupcakes with pictures of the actors in the movie topping each one. 

“Lauren wanted to be a teacher from before she even went to kindergarten,” her mother said. “We will miss her terribly and will take comfort knowing that she had achieved that dream.” 

Nancy Lanza, 52, mother of gunman
Investigators believe that Adam Lanza shot his mother at her home near Sandy Hook Elementary before driving to the school and killing 26 others, then himself.

Nancy Lanza was social and generous, friends and neighbors told The New York Times. A friend told NBC News that she was a gun enthusiast.

“She had a pretty extensive gun collection,” Dan Holmes said. “She was a collector, she was pretty proud of that. She always mentioned that she really loved the act of shooting.”

He said that she took her sons to the shooting range to practice their marksmanship.

In 2008, her husband Peter John Lanza filed for divorce, court records show. He lives in Stamford, Conn., and is a tax director at General Electric. 

Rachel D'Avino was 29.

Rachel was born in Waterbury, Conn., to parents Mary D’Avinio of Bethlehem, Conn., and Ralph D’Avino of Waterbury, Conn. She was a 2001 graduate of Nonnewaug High School and received her bachelor’s degree from the University of Hartford and her master’s degree from Post University. She was working toward her doctorate degree from the University of St. Joseph in Hartford, Conn.

A behavioral therapist who worked with special-needs kids, Rachel was one of two teacher’s aides who died at Sandy Hook. She joined the staff at Sandy Hook only about a week before the shooting, the Stamford Advocate reported.

She loved animals, cooking, baking, photography and karate, her family said, adding that she was an adoring big sister who cherished her two younger siblings like they were her own children.

“Her presence and tremendous smile brightened any room she entered,” Rachel’s obituary said. “Her maternal nature, understanding and sense of patience with the learning disabled were truly gifts she possessed. Ultimately, it is these gifts that would have given Rachel a level of understanding and forgiveness during this time of crisis that many others wouldn’t have.”

Rachel’s aunt, Christine Carmody, who lives in Florida, said that D’Avino’s boyfriend had asked her parents for her hand in marriage and planned to propose on Christmas Eve this year, Carmody told her pastor before flying to Connecticut, MyFoxTampaBay.com reported.

He was on the Newtown soccer team and the Newtown Torpedoes swim team.

Jimmy Green named a song from his 2009 disc for his daughter, Ana Grace, the Ottawa Citizen noted. The family had recently moved to Newtown, Conn., from Winnipeg, Canada, where Greene was a faculty member at the University of Manitoba’s school of music.

"In her short life, Ana strengthened us with her loving, generous joyful spirit," the family said in a statement. "She often left sweet notes that read, 'I love you Mom and Dad,' under our bedroom pillow -- not on special occasions, but, rather, on ordinary days."

In a statement posted by the Citizen, Greene thanked friends for their prayers and words of support: “As we work through this nightmare, we’re reminded how much we’re loved and supported on this earth and by our Father in heaven. As much as she’s needed here and missed by her mother, brother and me, Ana beat us all to paradise. I love you sweetie girl.”

He was born in Winchester, England, to his British father, Ian Thomas, and American mother, Nicole Marie (Moretti) of Sandy Hook. The family moved to Connecticut from England two years ago.

His grandmother, Teresa Moretti of Cranston, R.I., told the Boston Herald that Dylan loved garlic bread, bouncing on his trampoline and playing Wii.

“Dylan had dimples and blue eyes,” Moretti told the Herald as she fought back tears. “He had the most mischievous little grin. To know him was to love him.”

Dylan’s parents had lived in England for 18 years before moving to a house on the same street as Nancy Lanza in January, according to the Telegraph. Dylan’s 8-year-old brother, Jake, who also attended Sandy Hook Elementary, survived the shooting.

On Friday morning, he had his favorite breakfast sandwich at a local deli – sausage, egg and cheese, NBCConnecticut reported.

Family friend Barbara McSperrin told the Wall Street Journal that Jesse was “a typical 6-year-old little boy, full of life.”

“Jesse was such an incredible light. So bright and full of love. He lived life with vigor and passion … brave and true,” Jesse’s mother wrote in an email to the paper.

Fondly called “J” by his family, James was “an energetic, loving friend to all,” his obituary said.

He liked playing baseball, basketball, swimming, arm wrestling and playing games on the iPad.

James loved hamburgers with ketchup, his dad’s egg omelets with bacon and his mom’s French toast, the obituary said.

Annette Sullivan, the owner of Zoar Ridge Stables in Sandy Hook, Conn., told the Connecticut Post that James and his older sister Anna would ride horses at her stables.

“He would ask about the saddles and the brushes,” Sullivan told the Post. “He wanted to know how to take care of the horses. He was a boy that wanted to know how everything worked.”

His parents said in the obituary that he “was a numbers guy, coming up with insights beyond his years to explain the relationship between numbers and unique ways of figuring out the answer when adding and subtracting.”

His parents said James was especially thoughtful and considerate and was “always the first to welcome guests at the back door with a hug and his contagious smile.”

Emilie Parker, 6.

“My daughter Emilie would be one of the first ones to be standing and giving her love and support to all those victims, because that’s the kind of person she is, not because of any kind of parenting my wife and I could have done but because those are the gifts that were given to her by our heavenly Father,” Parker said.  

Emilie carried around pencils and crayons, and when people were sad, she would draw them a picture or write them a note. Recently, she dropped a card into the casket of her grandfather, who also died tragically, Parker said.

“I’m so blessed to be her dad,” he said.

In a later statement, Robbie Parker wrote: "Remember these beautiful children; keep them close to our hearts. Do not let their bright shining faces become extinguished. Let us do everything in our power to ensure their light will continue to shine brighter and brighter in all we do to remember them."

He was the youngest of the victims, having turned 6 last month. He was born in Danbury, Conn., to parents Lenny and Veronique Pozner, who described their son as “the light of our family, a little soul devoid of spite and meanness.” His twin sister, Arielle, who was assigned to a different classroom at Sandy Hook, survived the shooting. He also had an 8-year-old sister at the school, according to Newsday.

Rabbi Shaul Praver tended to Veronique Pozner in her grief.

“She said that she didn’t know how she was going to go on, and we encouraged her to focus on her other four children that need her and not to try to plan out the rest of her life, just take a deep breath right now,” Praver said, according to forward.com.

Noah’s uncle, Arthur Pozner of Brooklyn, N.Y., told Newsday that Noah was very mature.

“When I was his age, I was not like him,” he said. “Very well brought up. Extremely bright. Extremely bright,” he said. “The reason they moved to that area is because they did not consider any school in New York state on the same level. That’s one of the reasons they moved, for safety and education.”

His funeral and burial was held on Monday.

As the firstborn, her family said, Jessica “started our family, and she was our rock. She had an answer for everything, she didn’t miss a trick, and she outsmarted us every time. We called her our little CEO for the way she carefully thought out and planned everything.”

Jessica loved everything about horses, from reading horse books and drawing horses, to writing stories about horses, her family said in the statement from family friend Jamie Dunbar.

“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. We are devastated, and our hearts are with the other families who are grieving as we are.”

Allison N. Wyatt was 6.

Allison, daughter of Cheyanne and Ben Wyatt, was a sweet girl and a budding artist who would turn parts of her family’s Newtown home into an art studio, according to a family statement.

“Allison was a kind-hearted little girl who had a lot of love to give, and she formed special bonds with most people who spent any amount of time with her,” her family wrote. “She loved her family and teachers especially, but would often surprise us with random acts of kindness - once even offering her snacks to a complete stranger on a plane.” 

She loved to laugh and was developing a sense of humor beyond being just a silly 6-year-old, her parents said, “coming up with observations that more than once had us crying with laughter.”

A neighbor told the Connecticut Post that Allison would spend the summer outdoors, and that she often saw her gardening with her mother.

“Allison made the world a better place for six, far too short years and we now have to figure out how to move on without her,” her family wrote. “Our world is a lot darker now that she’s gone.  We love and miss her so much.”
