I never quite understood why bones and teeth don't burn if the fire is sufficiently intense. Even after massive fires people can often still be identified by comparing dental records.
If it were sufficiently hot to melt, or even evaporate, the calcium and other mineral compositional elements of the teeth, then certainly it could. Tautologically so, even. However, being anywhere near such a source of heat would not be a good idea. Maybe a mile away would be a good distance?
It is interesting to note that people can be i
dentified by their
dental records...
But if so, then what's the point of criminals burning their victims? No quickly improvised fire is going to get so hot as to completely destroy bones and teeth. But why bother then? Just put them in an acid bath and the bones in the grinder and scatter the fragments into the sea, I'd say.
Although burning won't make it impossible to identify the murder victim, it will destroy a lot of bodily evidence that could be used to convict the murderer. When people murder, they may leave behind DNA evidence. Their skin may be stuck under the victim's fingernails if there was a fight. A strand of their hair may be stuck to the victim somewhere. If there was rape, their semen can be used to identify them. Fire doesn't destroy teeth but it does destroy all that DNA evidence. It also makes it very hard to tell exactly how the victim was murdered, another thing that can prevent finding out who the murderer was.
Yes, you're right. I completely forgot about DNA traces and cause of death. Still, a
really thorough and clever murderer would get rid of the body entirely, for example using the method I described earlier, or by burning it and then blowing the remains to pieces with a highly explosive device.
