Police say a child pornography sting has yielded an arrest of a Hackensack man who allegedly recorded his stepdaughter and held a massive collection of disturbing images.

Authorities were investigating Graham Hurley, 50, for sexually abusing his 13-year-old stepdaughter when they say they found the man?s porn stash. Police found a secret room with a high-tech, fingerprint security system where Hurley allegedly kept 20 computers estimated to be filled with hundreds of thousands of images of child porn. He also had a big-screen television on which to view the images.

Additionally, Hurley allegedly used hidden cameras in the bathroom at his house to record his stepdaughter, as well as her friends, using the bathroom and showering at the Poplar Avenue home.

If convicted on all charges, Hurley would spend the rest of his life in prison.
