There will always be helpers. You know, just on the sidelines. Reporter: And how it would warm Fred's heart to see how that is actually happening now in his old neighborhood where the helpers are showing up. Like the surgeon who during the chaos on Saturday left his house across the street to see how he could help. I went down and said, can I be of any help to you, you know, somebody's hurt. And you need? I'm a surgeon. I can go in and help. Reporter: In the end there was not much Dr. Jeff Cohen could do on Saturday. Today in addition to mourning the friends he lost he's thinking this -- I think it's time for leaders to Stange up and be the helpers.

Anything we could do to help them feel safe and make sure one individual's darkness -- Today people were lining up to donate blood. Helping. The patients, the people are demonstrating today waiting to donate blood is Pittsburgh. It is community. They are saying, all right, I'm not going to get angry. I'm not going to get frustrated. I am just going to take the time required so I can give blood and replenish the supply that was used by the victims of the terrible shooting. I'm isn't really a commodity but I have much of but I can donate blood. I mean it's the least that I can do to help. I called my boss this morning. I said my heart is broken for my city and I need to go do something. She said, go. You're -- go, do whatever you got to do.
