ST. LOUIS, MO (KTVI) - The former Chesterfield cop who secretly took video inside a public restroom was cuffed and sent to jail today. A St. Louis County Judge found former officer David Cerna guilty of a charge he fought until the end.

It`s a case so bizarre, no one could`ve predicted the twists that brought us here. A 2014 Fox Files investigation led to evidence of a hidden camera inside a men`s restroom. David Cerna admitted it, but for months he`s fought one specific charge to avoid becoming a sex offender.

Today, a Judge found him guilty of that charge `Sexual Exploitation of a Minor.` Then the Judge told the bailiff 'take him into custody.'

Fox 2`s reporting on Cerna began in 2014, when a man on the East Coast said he found a disturbing web site, filled with images of men using a public restroom. Our investigation revealed an unexpected location -- a bathroom in the Mobile on the Run near Chesterfield Mall. When we took our findings to Chesterfield Police, we never imagined they would arrest one of their own officers.

Cerna pleaded guilty in February to operating the camera and posting pictures to his personal porn site, but he fought another charge involving his secret video recording of a teenager`s genitals during a pat down search. That charge was the only one in which a conviction would lead him to be a `registered sex offender.`

Today the Judge found him guilty and had him cuffed immediately. Cerna appeared to be near tears. The mother of one of the victims also cried as she said, 'I waited a long time to see those handcuffs.'

Prosecutors wanted him to serve seven years in prison. The Judge sentenced him to one year in the County jail, but said he could go to prison for ten years if he violates probation. Cerna faces another sentencing Monday in St. Charles County for charges surrounding Cerna`s operation of a glory hole in which he posted videos online.

About the FOX Files

The Fox Files are groundbreaking investigations you won’t see anywhere else. The series is well known for breaking the Pam Hupp story nationally. The reports that led to the exoneration of Russ Faria. But, it is far from the only time in which our investigations led to overturned convictions and freedom for the wrongfully accused. The Fox Files investigations do not fit into just one category, other than the fact our reports shine a light on issues and corruption in ways you won’t see anywhere else.

You won’t know what to expect as our reports often take twists that surprise even Fox Files investigator Chris Hayes.

“You never know where the truth will lead and you have to keep searching for it, even when you think you might be done,” Hayes said.

From getting arrested for trying to cover a public meeting, to getting law enforcement involved in his report about a daycare fight club, the Fox Files has been at the forefront of breaking news investigations in the St. Louis area.

It doesn’t stop just in St. Louis. The Pam Hupp/Russ Faria story took him to Lincoln County. Fox 2 was the first to report, nationally, on the synthetic drug epidemic when it began in St. Charles County, MO. In St. Louis County, our Fox Files reporting led to the dismantling of some police departments, including the departments of Uplands Park and Jennings. And in the City of St. Louis, our investigations led to swift government actions, such as our report that led to the Governor’s ordered shut down of a daycare.

Our reporting in St. Louis also led to former Missouri Governor Eric Greitens’ exclusive Fox Files interviews involving his court fight to oust the chief prosecutor while attempting to prove that political corruption led to an illegal overturning of a state election.

“It’s not always bad news,” Hayes said about a recent victory for a restaurant in his coverage of a St. Clair County Illinois issue. A Fox Files report, exposing a health department’s mistake over the COVID-19 pandemic, led to an overturning of a decision, allowing the business to open for limited inside dining.

Another investigation took us to Madison County, where prosecutors praised Fox 2’s coverage while shutting down an illegal synthetic drug business – and to Monroe County, where we uncovered key evidence in the Chris Coleman murder trial.

Even the national media, continues reaching out to local affiliate Fox 2 KTVI and the Fox Files, for its work on cases that are important to St. Louis. When you see a network television’s coverage of St. Louis, you’ll often see that they gathered information that was first uncovered right here.
