PORTLAND, Ore. – A former teacher at Portland Community College’s Rock Creek campus has been charged with invasion of personal privacy for allegedly hiding a camera in a campus bathroom.

Matthew Constantino, 39, of Scappoose, also had several “up-skirt” videos that were recorded off campus, according to Deputy Mark Povolny with the Washington County Sheriff’s Office.

Contantino was placed on leave in October of 2016 after a student found a hidden camera in a gender-neutral bathroom.

Detectives learned Constantino hid a camera under a sink and pointed it toward the toilet, Povolny said. They were able to identify multiple victims who had been recorded without their knowledge.

During a search of Constantino’s home, investigators found “up-skirt” videos filmed at other locations.

Additional charges will be filed against Constantino by the Washington County District Attorney’s Office.

Constantino was booked into the Washington County Jail and later released on Friday. He is scheduled to appear in court on May 5.

He is no longer employed at PCC.

Detectives have notified several victims in this case and are working to identify others. Anyone with information is asked to call the Washington County Sheriff's Office at 503-846-2500.

"Well we have more than three victims and sometimes it's hard for us to know who everybody is in the video based on where the camera is placed or some of the up skirting videos we don't always get identifying information on people," said deputy Mark Povolny of the Washington County Sheriff's Office. "That's why we're asking people if they think they're a victim or have information to let us know."
