PORTLAND, Ore. – Police arrested a 57-year-old Wednesday who’s accused of luring a child online.

Police first started investigating Mark A. Chervin in early October when the Sex Trafficking Unit received a tip about Chervin’s suspected criminal activity.

Chervin is a private music teacher and has access to children.

According to police, an undercover officer posed as an underage girl on social media and contacted Chervin.

Investigators say the 57-year-old claimed to be a much younger man when he reached out to talk to who he thought was a 15-year-old girl.

Chervin repeatedly contacted the officer and tried to build a sexual relationship, police said. The whole time, Chervin was under the impression he was talking to an underage girl.

"It did escalate in to a lot of different methods of communication," said Sgt. Mark Georgioff with the Portland Police Bureau's Sex Trafficking Unit.

Police said Chervin expressed he wanted to meet the girl “for purposes of a sexual nature," and arraigned a time and place to meet in Southeast Portland. When he arrived, the Portland Police Bureau’s Sex Trafficking Unit took him into custody.

Chervin was arrested and booked in the Multnomah County Jail on charges of third-degree attempted sodomy, first-degree online sexual corruption, second degree online sexual corruption, second-degree attempted sexual abuse and 20 counts of luring a minor.

His bail is set at $1,300,000. Court documents show officers are worried that if Chervin were to get out he would reach out to other victims. Investigators say after searching his Southeast Portland home they found evidence the teacher had been harassing and stalking other students.

Police believe there may be more victims.

Anyone who may be a victim or anyone with information about Chervin should contact the Portland Police Bureau’s Sex Trafficking Unit at 503-823-4867.
