On a Monday in March 2012, detectives with the Moore, Oklahoma, police department were called to a bloody scene at a Super 8 Motel.

They arrived before dawn to find a pool of blood at the bottom of a staircase and a path of bloody footprints heading toward an ice maker.

Lying face up underneath the bottom stair rail – almost as if it had skittered away during a struggle – was a Super 8 employee’s name badge.

Police said it belonged to a man named Anthony Lennon.

And that, officers would later tell CNN, made the entire crime scene feel suspicious.

Mere days before he disappeared, prosecutors had charged Lennon with eight counts of possession of child pornography.

But now, he was missing.

Had Lennon been attacked and abducted? Or, as law enforcement would come to suspect, did he stage his own kidnapping and vanish into the night?

Uncovering the truth would lead Moore police detectives and the US Marshals Service on a manhunt that would span 13 years.

“It was a cat and mouse game,” Moore Police Chief Todd Gibson told CNN. “When you commit crimes – when you victimize children – the full resources of (the law enforcement) community are going to come after you, and it’s never going to stop.”

In March 2012, Moore, Oklahoma police officers responded to a crime scene at a local Super 8 to find bloody shoe prints and what appeared to be a robbery.
