grazed by a bullet doesn't talk much about what happened. he was in a classroom across the hall from nick. when the shooting began. their parents were nearby waiting for school to let out. >> alex called and said mom i'm in the back of an ambulance. i was hit in the head. in my mind i didn't worry about it. there's 3,500 at that school. one child was shot what's the odds of two of my kids being shot. and i took off to the hospital. and said wait for nicholas. >> they waited for 12 hours before finally being told nicholas was dead. within days a mutual friend connected them with sandy and lonny. >> do you remember the first meeting? >> yeah, of course. they had a house full of people. we felt like we were intruding on a private moment. which we were. for a good reason. >> i was skeptical. in the beginning.
