He says immediately his heroic instincts kicked in, and he ushered shoppers into his store from the mall walkways, and out the back door to safety.

After the shooting ended, authorities actually questioned Christensen to make sure he wasn’t the shooter.

He is sharing his story with KDKA, as well as the pictures he tweeted.
