Man says he had shooter in his sights, but chose safety over firing

Meli earlier told a KGW reporter that he heard three gunshots, and then positioned himself behind a pillar in the mall. Meli said he saw the gunman working on his rifle, pulling a charging handle and hitting the side of the weapon.  

Meli said he then pulled out his Glock 22 pistol and aimed it at the suspect. But when he saw someone move behind Roberts, Meli decided against firing, concerned he might hit an innocent person.

Meli also told KGW that Roberts appeared to spot him and that afterward, Meli heard only one more shot, and suspects it was the one Roberts used to kill himself.
