Is It Too Late to Test Scalia's Body?

NYT reports:

[In the absence of a full autopsy, [Dr. Michael M. Baden, a former chief medical examiner in New York City] said, officials could obtain critical information even from an embalmed body by inserting a needle into the heart or a tube into the bladder to perform toxicology tests on blood and urine for evidence of toxins. Sophisticated testing could distinguish drugs and chemicals from those in embalming fluid. It is not known if officials performed such tests in Justice Scalia’s case.

Although Justice Scalia’s body could have appeared relaxed and asleep without showing any external signs if he had been poisoned, a natural cause is the most plausible explanation for his death, Dr. Baden said.
