Hungry Burglars Should Eat Chocolate
Forensic dentistry, most commonly associated with identifying plane crash victims, has also helped the police identify hungry burglars who find it hard to resist snacking on food they find in their victims' houses. But, even if they wipe their fingerprints, they don't clean their plates, leaving police their tell-tale left-overs. In the past 10 years, a few criminals have even been identified and convicted of their crimes because they left their bite-marks behind.
Now we have even more evidence to catch the thieves; Traces of saliva left on food can hold enough DNA to identify a criminal.
Interestingly, chocolate is almost useless in identifying DNA. This could be due to the small size of the left-over pieces, rather than the chocolate itself.
