Medical Science Doctor, Hamza Zujo, walks by the flags put next to the bones found in Lake Perucac, Sept. 22, 2010. âThis is the most humane job,â Dr. Zujo says about volunteers who came to help. âBut I think there should be more volunteers because that would speed up the process of finding the bodies.â Dr. Zujo said that heâs expecting a lot of blood samples because there are 800 people missing and 348 were found in the lake.
