>> so what was the decision that was made? >> we decided to -- do -- i guess, for lack of better description, a surgical decapitation so we could get the collar off safely and intact. >> so you took the victim's head off? >> yes. it was -- one of the hardest decisions i've ever had to -- make -- both professionally and personally. >> after completing that grim procedure, coroner timon met with brian wells'family and told them about it. they felt brian was being victimized again, even in death. >> how painful is that for you? >> well, it was very painful. i think it was most painful for my mom because, like, she wanted to have a open-casket. they were more concerned with the integrity of the collar than they were his person. >> pain on pain on pain on pain, jean, huh? >> yep. he was decapitated like john the baptist. >> with the pieces of the device recovered, tom stankiewicz was able to go into his shop and craft an exact replica of the bomb -- 340 parts in all. it is a frightening model.
