Missing persons experts call cases like the one out of Ohio this week "miracle finds" but these kind of discoveries are becoming more common.
Law enforcement, criminal profilers and missing persons advocates are now focusing on the predators who kidnap and hold victims captive for years.
Monica Caison runs the CUE Center for missing persons out of Wilmington, NC.
"They live in their own world and they think nobody has the right to come into their home and they secure their home," Caison said of the abductors.
They may get away with it because neighbors don't want to get involved.
"I think they live in a sick reality and unfortunately if you kind of mind your own business in a neighborhood, people leave you alone and don't try to get to know you," she said.
Caison encourages people to keep an eye on people who may be at risk and notice when something doesn't seem right.
If certain areas of the house are off-limits for no reason, that may be a red flag.
People can also stay vigilant by getting informed on who's gone missing in your area through web sites and flyers.
"Read a story and share that information because you never know where that information may land," she said.
A sign meant to make people think also got people talking in the Town of Blacksburg.
