COSTELLO: Dr. Jerry Umanos once said he felt called to work in Afghanistan treating children and training other doctors. The Chicago pediatrician was one of three Americans killed Thursday by a gunman who had been assigned to protect them. An Afghan security guard fired on Umanos and four others at their hospital. Now Umanos' wife says her family still loves the people of Afghanistan and holds no grudge against the alleged shooter. For more on Dr. Jerry Umanos and his legacy, I want to bring in Dr. Chawn Watkins, a friend of Dr. Umanos. The two worked together for seven years at the Chicago hospital. Welcome.</s>DR. CHAWN WATKINS, FRIEND OF DOCTOR KILLED IN AFGHANISTAN: Good morning.</s>COSTELLO: Good morning. Tell us about Dr. Umanos and why he felt compelled to volunteer his time in a dangerous place to help the children of another country.</s>WATKINS: Well, Jerry wanted to serve people. He was a servant at heart. Wherever there was a need and he felt like he could be a part of it and be a part of the solution, he wanted to do it. At our health center on the west side of Chicago, he came there to help serve a need there and he helped to train myself and other young doctors. I started working with him right out of residency and he helped to make me into the pediatrician that I am today. So wherever there's a need, he wanted to be there to train other people to do the work and then he saw Afghanistan as another opportunity to do that.</s>COSTELLO: His wife came out with such touching comments. She said, you know, we've suffered a great loss but we still love the people of Afghanistan. We don't regret that Jerry was over there doing the good work. It might surprise a lot of people.</s>WATKINS: It might but when you have a servant's heart as Jerry did, it's not surprising at all to any of us.
