On a mild November morning in rural California,

the leaves of the sycamore trees dotted the road with striking yellows and reds.

But John Banderhyden wasn't paying attention to the foliage.

He was looking for any sign of his daughter, Cindy.

As he drove by the town cemetery, something caught his eye,

along the rows of graves was a single car.

He recognized it instantly. It was Cindy's.

John made a sharp turn into the parking lot and came to an abrupt stop.

He hopped out of his car and walked towards the familiar vehicle.

Distressingly, there was no sign of Cindy.

He tried the door handle and realized it was unlocked.

Her purse lay on the driver's seat. He felt dread, curl, and his stomach.

At 25, Cindy had just turned her life around.

After a few years of drug use and too much partying, she moved back in with her parents,

gotten clean, and started a new job. She'd been saving up for months to buy this car.

It represented her fresh start. There was no way she'd leave it unlocked like this.

As he stood there, his worry curdled into fear. He could feel it,

something terrible had happened to his daughter.
