Those of you with a slightly weak constitution should probably skip ahead to the next slide now. Others, well, read on. In 1850, a baby was found in a Parisian apartment by the couple living there. So far, so weird, but the freaky part was that the baby was mummified. And in the wall. Pretty soon after, the couple were charged with murder.
Here's the interesting part to this sad tale. The couple were cleared of the murder, because a physician proved, for the first time ever in French court, the approximate time of death by using insects. Insects! You don't see that too often on CSI. Anyway, basically the child had been long gone, long before the couple even moved in. Hooray for bugs, boo to murderers.
