BUT I THOUGHT THE SCIENCE WAS SETTLED: Pig Corpses Poor Model For Establishing Time Of Death In Humans:
The study, conducted by researchers from the University of Tennessee’s Forensic Anthropology Centre – better known as the Body Farm – examined how 15 pigs, rabbits, and humans decomposed in the same environment. To pull this off, the team broke the experiment into three trials, leaving five of each type of corpse outside during winter, summer, and spring.
In the end, they found that all of the test subjects decomposed a vastly different rates – with pigs decomposing faster than humans on average – and that the human body varied more wildly from body to body than the rabbits or pigs did.
Forensic science in general seems to be much less precise than was advertised for decades.
