NEWTOWN, Conn. For a third straight day Wednesday, funeral processions rolled through a grieving Connecticut town trying to make sense of the massacre of 20 first-graders and six adults in an elementary school less than two weeks before Christmas.
Dr. Joseph Young, an optometrist, said he has already been to one funeral and plans to attend two or three more.
"The first few days, all you heard was helicopters and now at my office all I hear is the rumble of motorcycle escorts and funeral processions going back and forth throughout the day," he said. "It's difficult. It's just a constant reminder."
Most students in Newtown went back to school Tuesday except those from Sandy Hook Elementary, where a gunman armed with a military-style assault rifle slaughtered the children and six teachers and administrators Friday. He also killed his mother at her home. If police know why, they have not said.
Students at Sandy Hook, which serves kindergarten through fourth grade, will resume classes in a formerly shuttered school in a neighboring community in January.
President Obama on Wednesday pressed Congress to reinstate an assault weapons ban, which expired in 2004. He also called for stricter background checks for people who seek to purchase weapons and limited high capacity clips.
"This time, the words need to lead to action," said Mr. Obama, who set a January deadline for the recommendations.
In the meantime, mourners overlapped at back-to-back funerals that started Monday and will continue all week.
The first of Wednesday's funerals in Newtown was for 7-year-old Daniel Barden, a gap-toothed redhead and the youngest of three children whose family described him as "always smiling, unfailingly polite, incredibly affectionate, fair and so thoughtful towards others, imaginative in play, both intelligent and articulate in conversation: in all, a constant source of laughter and joy."
Hundreds of firefighters formed a long blue line outside St. Rose of Lima Catholic Church as bells sounded and bagpipes played. Daniel wanted to join their ranks one day, and many came from New York, where his family has relatives who are firefighters.
Eddy Bowls, a FDNY firefighter, told CBS News correspondent Elaine Quijano: "The firefighters are here in tribute to this young child. It was a beautiful service. It appeared to be a wonderful child whose life was cut too short."
Family friend Laura Stamberg of New Paltz, N.Y., whose husband plays in a band with Daniel's father, Mark, said Daniel was a thoughtful boy who held doors for people and would sit with another child if he saw one sitting alone.
She said that on the morning of the shooting, Mark Barden played a game with his son and taught him a Christmas song on the piano.
"They played foosball and then he taught him the song and then he walked him to the bus and that was their last morning together," Stamberg said.
At the same time, in the town of Stratford, family and friends gathered to say goodbye to Victoria Soto, a 27-year-old teacher who has been hailed as a hero for dying while trying to shield her students, some of whom managed to escape.
"We heard at one point that they found some people hiding in a closet. And all of us said, 'Vicki would never be hiding in a closet.' She would be out there protecting those babies," Soto's mother Donna Soto told "CBS This Morning" co-host Gayle King.
"She had the perfect job. She loved her job," said Vicky Ruiz, a friend of Soto's since first grade. Every year, she said, Soto described her students the same way. "They were always good kids. They were always angels," even if, like typical first-graders, they might not always listen, Ruiz said.
At Soto's funeral, the crowd was so large people stood outside. Inside, singer Paul Simon performed "Sound of Silence."
Sandy Hook's fire department stood at attention for student Caroline Previdi's funeral procession. She loved to draw and dance.
Family friend Joseph Secola said: "It was just heartbreaking seeing the casket. Obviously the girl is so young. She obviously was a joyous girl and that is what they have to hold onto."
Charlotte Bacon, the seventh student to be laid to rest since the shooting, was remembered for her love of animals and the color pink.
Calling hours were being held for popular 47-year-old principal Dawn Hochsprung. She and school psychologist Mary Sherlach rushed toward Lanza in an attempt to stop him and paid with their lives.
Hundreds of mourners flocked to a wake in suburban Katonah, N.Y., for 52-year-old Anne Marie Murphy, one the teachers killed in the shooting.
They waited in line, some for more than an hour, outside The Clark Associates funeral home Wednesday to pay respects for Murphy.
The funeral home says the former Katonah resident is survived by four children, her husband, her parents and six brothers and sisters.
A nephew of Murphy, Taylor McGowan, commented on the large turnout, saying "if you knew her, you wouldn't be surprised.
Murphy's funeral will be held Thursday at St. Mary of the Assumption Church. Burial follows at St. Joseph's Cemetery in Somers.
The massacre continued to reverberate around America as citizens and lawmakers debated whether Newtown might be a turning point in the often-polarizing national discussion over gun control.
Private equity firm Cerberus Capital Management announced Tuesday it plans to sell its stake in Freedom Group, maker of the Bushmaster rifle, following the school shootings. In Pittsburgh, Dick's Sporting Goods said it is suspending sales of modern rifles nationwide because of the shooting. The company also said it's removing all guns from display at its store closest to Newtown.
Lawmakers who have joined the call to consider gun control as part of a comprehensive, anti-violence effort next year included 10-term House Republican Jack Kingston, a Georgia lawmaker elected with strong National Rifle Association backing.
The National Rifle Association, silent since the shootings, said in a statement that it was "prepared to offer meaningful contributions to help make sure this never happens again." It gave no indication what that might entail.
And no indication has been made publicly about the motive of 20-year-old Adam Lanza, who, clad all in black, broke into Sandy Hook Elementary and opened fire on students and staff.
Authorities say the horrific events of Friday began when Lanza shot his mother, Nancy, at their home, and then took her car and some of her guns to the nearby school.
Investigators have found no letters or diaries that could explain the attack.
