But a missing Citrus County woman was found a different way – through her scent. The woman, who has dementia, had been missing from her Sugarmill Woods home earlier this week.

Fortunately, she had used a scent preservation kit, which helped K-9 deputies track her down -- in fewer than five minutes!

A scent preservation kit stores someone’s unique smell so that if they’re ever missing, they'll be easy to find. Here's how it works -- a person takes a sterile pad in the kit and wipes their armpit 2-3 times. The pad is then stored inside a sealed container and if the person ever goes missing, a K-9 can track them down through their unique scent.

Pretty fascinating!

2 Wants to Know reached out to Triad police departments to see what they think about the kit.

Greensboro police said their bloodhounds can track a scent from any piece of clothing. While a scent preservation kit is nice, it's not necessary.

High point police told us they contact Triad Blood hounds when they need to find a missing person but added the kit is nice to have. It won't have anyone else's scent on it.
