According to Fairfax County Police, Raphael Schklowsky had used a hidden camera to record a woman inside his home. The woman told investigators she found the camera inside an A/C vent.

Nearly one month later, police announced that in addition to four misdemeanor counts of unlawful filming in that case, they had arrested Schklowsky on at least 20 felony charges of child pornography possession after they found more evidence on electronic devices, including 3,500 videos.

During a Wednesday news conference, police said they discovered the victims while combing through the mountain of evidence that surfaced during the investigation.

Upon his initial arrest, Schklowsky was placed on leave from the school district.

After receiving public support and information, detectives identified 10 victims "that could be recognized based on the evidence collected." They say "all other images and videos did not provide enough identifiable characteristics to positively make any definitive identification."

Detectives obtained 10 felony warrants for unlawful creation of an image or other still and video images and served Schlowsky Thursday at the Adult Detention Center where he is currently incarcerated.
