This did happen in my town about 2 years ago. There was a big fire in an apartment building and this fatty lived on the FIRST floor (over 500 lb I believe) and they STILL couldn't get her out because as the fire dept. explained later, it would have required getting it on a tarp and six men to get it out. They couldn't spare the six men because they were all busy rescuing normal people and by then it was too late for fatty.  It's ham relatives sued the town but the town won.
