Commander Dean Nyhart of Arizona Dept. of Public Safety, said, "We don't have any fingerprints to help match it up to the people that we have here that are deceased at the scene, so it's going to be a lengthy investigation just to identify the deceased people and get the right passports back into the right hands right now. But we obviously have a language barrier from the few people that could actually talk to us initially at the scene, which was another tour bus full of Chinese nationals that stopped to help initially. They were able to provide some interpretation for us."
