Colorado on the Web column preview: 15 years after Columbine shooting

Published: April 23, 2014, 9:30 pm, by Dalton Walker

Dateline NBC chronicled the journey of Denver resident Sam Granillo. Granillo was a student at Columbine High when it was attacked April 20, 1999.

Watch the Dateline videos here. Follow Granillo on Twitter here and for more on a project Granillo is working on called Columbine: Wounded Minds, visit here.

I will link to my column once its published Thursday.

Thanks.
