FONTANA (CBSLA.com) — The president of the Buena Park School District’s governing board has been arrested on suspicion of trafficking child pornography.

Dennis Brian Chambers, 50, was arrested Wednesday on the front lawn of his home in the 8000 block of Taylor Street in Buena Park, according to police in Fontana.

Officers searching the home found an electronic storage device containing thousands of child pornographic videos and images, according to Fontana Police.

Authorities say the department’s Internet Crimes Against Task Force detectives have spent the past six months working with its counterparts at the Flathead County Sheriff’s Department in Montana to root out people distributing child pornography over the Internet.

Investigators who had captured several videos and images from various members of the group determined that one suspect, identified as Chambers, had trafficked child pornography in Fontana.

Chambers is a father and grandfather.

CBS 2’s Michele Gile spoke to shocked colleagues and family members who would never have guessed in a million years Chambers could have been involved with something like child porn.

“How does anybody feel when you hear that? It’s heartbreaking,” said his former sister-in-law.

Chambers, who was booked at Santa Ana Central Jail and is being held on $250,000 bail, is currently serving as president of Buena Park School District’s governing board through 2018.

Gile reported he was elected twice to his post.

Greg Magnuson, Superintendent of the Buena Park School District, was outraged.

“We’re all shocked by this news,” he said, “disappointed obviously. But more and more, we actually angry about it.”

At 5 p.m. the school board called a special closed door meeting to discuss the matter and potential litigation as the result of Chambers’ arrest.

Chambers is scheduled to be arraigned Friday.

Picking up the story for KCAL 9 News at 10 p.m., reporter Erica Mandy spoke to parents — like Larry Carrillo and Crysie Quinones — who expressed shock and concern that no children in the district were harmed in any way.

“Of all people” said Carrillo. “[I’m] mad. Cause we entrust that when we send [our kids] to school, that’s the safe zone. Basically, you have someone being called a predator in charge of it all.”

Quinones echoed that sentiment.

“I’m shocked. These are the people who are supposed to be for our kids’ education,” she said, “and he’s doing stuff like this. It’s just, terrible.”

Officials said there is no evidence that any children in the district were victimized in any way.
