It was July 12, 2013, and Melissa Richards had decided to take her dog Remy for a walk in the

Richfield Nature Park near her home in Wisconsin. This was a remote park but it was beautiful and on

this breezy summer day it was the perfect place to let her dog run around and be free for a while.

When Melissa pulled up to the park's entrance, she only noticed one other vehicle,

a blue minivan.

If you could see a person inside, the young man's face was turned toward the passenger

door and he had his legs kicked up and dangling out the window.

Melissa shrugged it off and just figured he was there for the same reason she was.

Privacy, and a little bit of mother nature.

Melissa and her dog Remy roam the grassy park for about half an hour,

basking in the sunlight and the sweet summer smells.

But it was super hot out that day and her dog needed some water.

So Melissa decides to head back to the car.

As she walks the rocky path back towards her car, she notices that guy from the blue

minivan.

This time his eyes are locked on her. Melissa continues toward

her vehicle. Then she senses something behind her. That eerie feeling of a strange body getting too close.

She hears footsteps shuffling in the gravel. She whips her head around and the man is at her heels.

Oh, you scared me, she says. He's tall and slender with pale skin and dark thick-rimmed glasses.

Melissa gasps. He's getting closer.

Then, she notices the knife. He's gripping the weapon so tight

his knuckles are white. He lunches at Melissa in one swift motion, knocking her flat on the ground stomach first.
