The first three died in the space of just over a week in November. Benito Que, 52, was an expert in infectious diseases and cellular biology at the Miami Medical School. Police originally suspected that he had been beaten on Nov. 12 in a carjacking in the medical school's parking lot. Strangely enough, though, his body showed no signs of a beating. Doctors then began to suspect a stroke.
