Two California brothers, both of whom had coached for more than a decade in San Jose public schools, were arrested within a week of each other on suspicion of possessing child pornography.

As the San Jose Mercury News reported, Clifford Pappadakis surrendered to police on Feb. 14 and is expected to face charges including child porn possession and child molestation.

Police began looking at the suspect, who taught and coached the cross-country team at Willow Glen Middle School, at least as early as last September after a parent complained that he had taken photos of a minor girl wearing “a skimpy bikini,” according to court documents.

The alleged incident occurred during swimming practice on Sept. 7, which had been organized by Pappadakis.

Similar allegations surfaced months earlier when a complainant said the coach had been spotted taking “an unusual amount of photos at events and of cheerleaders.”

On Tuesday, six days after he turned himself in, his twin brother, Clinton Pappadakis was arrested based on accusations of possessing child porn.

The track coach had been reported to authorities for “suspicious activity” in September. In accordance with a search warrant, investigators said they found illegal images of children on “multiple devices” in his possession.

Santa Teresa High School track-and-field coach Scott Young, who served on a local athletic committee with Oak Grove High School coach Clinton Pappadakis, said he would have never expected such allegations against the 47-year-old.

“Just shocked and saddened,” he said. “This is not something I thought was a possibility. It’s just sad and disheartening.”

Reports indicate both brothers prompted some level of investigation last year, though authorities say the cases are not related.

It was not immediately evident whether allegations against one of the men sparked police interest in the other.
