NEWTOWN, Conn. – The signs are easy to miss, but a Connecticut group believes gun violence is preventable if people are more aware.

Sandy Hook Promise, a group based in Newtown, Conn., released a chilling public service announcement meant to raise awareness about gun violence.

On the surface, the video follows the story of a student named Evan, who engages in what appears to be a cute romance with another student. They exchange messages by writing on a desk in the library, and Evan is enamored with his mysterious paramour.

But while he focuses on his mystery girl, he misses signs from another student, who shows up at the end of the video entering the school with a gun, sending students scrambling.

And the signs, if you watch the video carefully, were there all along. The student is reading a magazine and watching YouTube videos about guns. One of his social media posts shows a selfie in which he holds a firearm.

Evan misses these signals while he thinks about his mystery girl.

The group behind the video formed after the Sandy Hook Elementary shooting on Dec. 14, 2012. In that case, Adam Lanza killed 20 children and six adults at the school in Newtown, Conn.

The group’s mission is to “honor all victims of gun violence by turning our tragedy into a moment of transformation by providing programs and practices that protect children and prevent the senseless, tragic loss of life.”

Nicole Hockley, whose son died in the Sandy Hook shooting, told WTIC that she believes the signs were before the tragedy and wants to prevent it from happening again.

“Knowing that my son’s death was preventable but no one recognized the signs and was able to connect them to give the shooter help that’s part of what drives me to ensure that other families don’t suffer this same tragedy,” Hockley said.
