Unbeknownst to Suzanne, the man she'd gone home with led a double life - outwardly, a mildly colorful character studying for a criminology degree. Inwardly, he was a serial killer fanboy who admired the usual selection of scum, from high-profile civilian murderers to Hitler-era Nazis. Where some people want to be famous for something worthwhile - he wanted to be known as a cannibalistic serial killer. He even had a cutesy nickname that he kept trying to get the press to use.
She escaped his apartment briefly, but he shot her from behind and dragged her back. But in the end, it was her escape attempt that left the evidence that led to the thug's capture - and, undoubtably, saved the lives of other women.
These days the thug passes his time in prison, occasionally trying to convince other prisoners to help him escape into death.
