A sex offender in South Carolina had his kidnapping all planned out. He booby-trapped his bunker that was nestled underground where no one would find them.

What Vincent Filyaw, 37, didn't count on was his victim getting a hold of his cell phone and texting her location to her mother.

The girl sent her location to her mother but police had to use cell phone towers to find the secret location. The 14-year-old girl took the cell phone while Filyaw slept.

The bunker -- barely visible from the outside was equipped with electricity and a stove. The location is only one mile from the girl's home.

When police arrived they found Filyaw armed with a knife, a pistol and a taser gun. The girl was brought to safety.
