Duluth, MN (NNCNOW.com) - On the 15th anniversary of the school shooting at Columbine, Dateline will air "The Road Home," Sunday night at 7 p.m.

Survivor Sam Granillo opens up to Lester Holt in his first in-depth interview about the shooting and the aftermath...years later.

Lester joins Granillo on an emotional journey across the country... as he meets survivors of other school shootings.

One of their stops is Red Lake, Minnesota, where in 2005 a teenager shot and killed five students and two adults at the school.

Holt previewed the Dateline special with Michelle Lee on the KBJR 6 & Range 11 News at Five.
