(CBS News) NEWTOWN, Conn. - In Newtown, Connecticut, more children and a teacher -- victims of the deadly shooting at Sandy Hook Elementary School -- were laid to rest Wednesday.
Firefighters from across the northeast came to honor seven-year-old Daniel Barden. He wanted to be a firefighter someday.
"The firefighters were here in tribute to this young child and all the souls that were lost in this community" said Eddy Bowls of New York.
Sandy Hook's fire department also stood at attention for Caroline Previdi's funeral procession. She loved to draw and dance.
And at teacher Vicki Soto's funeral, the crowd was so large that people stood outside. Inside, singer Paul Simon performed "The Sound of Silence."
"It was just heartbreaking when you see the small casket," said family friend Joseph Secola. "You think the girl is six years old. But she obviously was a lovely girl who gave joy to a lot of people, and that is what they have to hold on to."
Charlotte Bacon, the seventh student to be laid to rest since the shooting, was remembered for her love of animals and the color pink.
There is still no clear evidence as to what triggered Adam Lanza's rampage. The medical examiner is bringing in a geneticist to see if Lanza might have had a medical condition that could have played a role in the shooting.
