Due to the graphic nature of this killer's crimes, listener discretion is advised.

This episode includes discussions of kidnapping, sexual assault, rape, child abuse, and murder

that some people may find offensive. We advise extreme caution for children under 13.

Today's episode features some crimes that are still officially considered unsolved,

38-year-old Christopher Wilder leaned against his Porsche,

watching the other drivers speed around the racetrack. The day before he had entered the Miami

Grand Prix, but it wasn't the action on the track that drew Wilder back. It was something else.

Wilder shifted his attention to one of the promotional models working the sponsor tends.

He thought 20-year-old Rosario Gonzales had beautiful Auburn hair. Wilder got in his Porsche

He said that he'd noticed her the day before and thought she was beautiful. Rosario quickly

flashed her engagement ring, but Wilder assured her he wasn't propositioning her for a date.

He was offering her a job. In addition to being a race car driver, he was also a photographer.

As proof, he pointed to his professional camera on the back seat. With his help, Rosario could

be on the cover of fashion magazines around the world. All she had to do was get in the car.

Wilder flashed a handsome grin and promised to have her back in time to see the next race.
