Oregon dad recounts confronting school shooter

The first time we're hearing from the father who killed a teenage gunman ending a deadly rampage at an Oregon elementary school last week. Caleb Giammanco's two daughters attend Silver Rail Elementary. The 36-year-old carpenter dropped them off that morning at lunchtime. He passed by the school and saw someone carrying a long gun shoot into a pickup truck. Then there's a person mowing the school's lawn. He says panic fled into his brain. He grabbed a handgun from his truck He went after the gunman, first telling 911 operator, I have to go in, people are going to die. He sat down with Oregon Public Broadcasting to describe what happened next. I started hearing children pleading for their lives, and then I started hearing gunfire, and I just started army crawling faster and faster, and I told myself, this is probably the last thing that I'm ever going to do. I found my opportunity and I seen a teacher on the left struggling with the gunman on the right with the rifle and I knew that they were they were both side to me and I knew that he did not know that I was there and so at that point I swung the door out and open and I stepped in and I fired I called my mom and I told her you know I called her and I was like mom I just I just had to take the life of what I think might be a child because he went into my daughter's school with a gun. That gunman killed three children and a teacher. Jim Manko says he's sorry he could not save everyone. We've credited him with saving numerous other lives that day.
