D'Avino, 29, was a behavioral therapist who hadn't worked long at Sandy Hook Elementary. She had just completed her requirements to become a certified behavior analyst, the New Haven Register reported.

"That was Rachel — a hard worker, a risk taker, a winner," her sister Sarah D'Avino said, according to the Register. "She excelled at everything she did, such as her incredible patience and ability to work with those with special needs, adults and children alike."

Dylan Hockley's public memorial service at the Walnut Hill Community Church in Bethel Friday afternoon included New York City Port Authority bagpipers and purple and white balloons. Dylan's mother remembers asking him once why he flapped his arms when he got excited.

Dylan, who had a form of autism that hindered his language development, answered: "Because I am a beautiful butterfly," said Nicole Hockley, who shared the anecdote Friday, according to the New Haven Register.

She referenced the so-called "butterfly effect," a theory that the flapping of a butterfly's wings can cause a chain reaction that influences weather a world away.

"If one butterfly can cause a hurricane, then 26 butterflies can change the world," she said.

Dylan's family moved to Sandy Hook two years ago from Hampshire, England. At the end of the ceremony, everyone gathered outside the church and applauded as Dylan's parents and brother released purple and white balloons.

Late Friday morning, at St. Stephen Church in Trumbull, Sandy Hook school psychologist Mary Sherlach – who rushed the gunman who killed her and 26 others -- was remembered as a caring professional, a Miami Dolphins fan and someone who ultimately put the lives of others ahead of her own.

A standing room-only crowd filled St. Stephen to mourn Sherlach, 56, who was remembered as "very loving and caring," said Brian Wallace, spokesman for the Diocese of Bridgeport. The Rev. Stephen Gleason presided in the Mass that was also attended by former U.S. Rep. Christopher Shays. He said it "was a blessing" to be present at the service for a woman who gave her life for the children of her school. The funeral was a "celebration of her two daughters and husband," said Shays.

The church was adorned with a Christmas tree and several wreaths, including one with the teal and orange colors of the Dolphins.

Gleason said her love was Christlike: "No one has greater love than to give one's life for his friends," he said. "And she did so in an attempt to save others."
