K-9s in Chester County are continuing their training to find human remains, whether it's above ground, or feet below. The dogs are part of Search and Rescue Dogs of Pennsylvania, a non-profit organization.
Vicki Wooters, the president of the Search and Rescue, said, "The dogs found bodies, one was four feet down wrapped in a tarp, another was dismembered and out in a landfill, another was in the river."
The dogs can pick up the slightest scent.
Wooters said the organization has helped state police and even the FBI find bodies all over the country, with about 20 cases a year. She said they recently found a body in Montgomery County.
"Some of the searches we've been on and some of the cases that we've helped solve the police have been very open when they said, 'Without that dog, we'd have never found this person,'" she said.
Some of those K-9s are also certified in tracking, trailing and water recovery searches as well.
