(KPLR) - A former Chesterfield police officer admits he's guilty of recording men going to the bathroom and posting it to his porn site.

FOX Files investigator Chris Hayes busted him in 2014 and was the only reporter in the courtroom today.

While in that courtroom we learned David E. Cerna wasn't just videotaping men at the Mobile on the Run on Clarkson, he also admitted hiding a video camera in the his police department locker room.

FOX 2 broke the case two years ago in May. It began with a tip from a man living in the northeast who said he found a disturbing web site where it appeared someone was hiding a camera in a St. Louis area bathroom.  Our FOX Files investigative team began searching two counties based on his information.  After several days, we found the bathroom.  We never imagined that when we took our findings to Chesterfield Police, they would find one of their own officers responsible.  Now former officer David Cerna admits he also hid a camera in his own department's locker room.

He pleaded guilty to two counts, one of which is a felony.  He could face up to seven years in prison when he's sentenced this April Fool`s Day.  We caught up with him after court as he walked out with his mom.

Reporter Chris Hayes asked, 'What do you say to all the men and boys who used the bathroom where you hid a camera?'

David Cerna said, 'No comment.'

Hayes: 'What about your former police officer colleagues?'

Cerna: 'No comment.'

Cerna still faces charges of secretly videotaping a teenager`s genitals during a pat down search.  Police said he used an iPhone to do that.  The unresolved charge is potentially the most serious.  As of now, his invasion of privacy convictions, even though one is a felony, will not classify him as a sex offender.
