DENVER - This weekend marks the one-year anniversary of the deadly shooting rampage at a movie theater in Aurora, Colorado.

Twelve people were killed and dozens more wounded when a gunman opened fire during a midnight screening of "The Dark Knight Rises" on July 20, 2012.

A day of remembrance gets underway in Aurora on Friday, leading up to a moment of silence at 12:38 a.m. Saturday, the moment the shooting happened.

Among those taking part is Stephen Barton, who is putting his focus now, on curbing gun violence in America with the"No More Names: National Drive to Reduce Gun Violence" campaign.

Barton spoke with KARE 11 Sunrise from Denver, CO about his mission.
