Wow! Hahn Certainly has major sores on his face and head. I don't see how he would get those from a few smoke detectors, Unless he extracted the americium and was really messing with it. Skin lesions can be a symptom of acute berylliosis. Maybe he was trying to make neutrons in a big way and was working with beryllium.
Stealing smoke detectors would indicate he was desperate. You can buy them for about six dollars each.
