Human Scent Preservation Kits
While tracking the missing person, Human Scent Preservation Kits come in handy. This strategy has been used by police officials and nonprofit organization for a long time. All one has to do is to press the armpit with sterile cotton, put it in a jar, and after sealing it, one should not forget to label it. It helps in easing up the process of finding a missing person as the officials can make use of any of their dogs after having them exposed to the smell.
