Among those who gathered in Newtown, Conn., were 13 survivors of the 2005 school shooting on the Red Lake Indian Reservation. The group drove nearly 1,500 miles to support and comfort the families and survivors.

They brought gifts intended to convey a message of resilience and hope, including a plaque that survivors of the 1999 Columbine shooting gave to them after their experience.

"This is just something we had to do," said Ashley Lajeunesse, 23, who was in the Red Lake classroom.
