President Barack Obama is to attend an evening vigil in Newtown, Conn., to mourn with a town trying to comprehend the massacre of its children and teachers.
His visit Sunday to the southeastern Connecticut community comes two days after a man opened fire inside Sandy Hook Elementary School killing 26 people, including 20 boys and girls no older than 6 or 7.
Authorities say 20-year-old Adam Lanza first killed his mother before driving to the school, opening fire in two classrooms and then taking his own life.
Obama will visit privately with the victims' families and with emergency personnel who responded to the shootings before speaking at an interfaith vigil at Newtown High School.
This is Obama's fourth trip as president to a community still grieving from a mass shooting.
