|In 1979, P,
a 61-year-old man, is operated on by Dr. D for removal of his appendix
and gall bladder. On February 18, 1979, P suffers severe abdominal
pains. An X-ray taken that day reveals a hemostat inside P's side.
P dies February 22, 1979. Doctors A and B perform
an autopsy on P prior to interment. P's executor sues
Dr. D for malpractice and wrongful death. Dr. D's negligence
is conceded, but the cause of death is contested. A testifies for
the plaintiff that the hemostat killed P. B testifies for the defendant
that D died of other causes. What is the role of the experts, judge,
and jury in this situation?
