The girl listened to Portland police officer Heidi Kreis talk about sexual harassment at her school three weeks ago.

Afterward, she confided in the officer that she’d been a victim of unwanted touching for years: A man had been groping her buttocks and breasts -- and he was still at it, she said.

The girl also said the man had been touching another girl, too.

The report set in motion an investigation -- which led to both girls undergoing interviews at the child-abuse evaluation center CARES Northwest. Both girls said the abuse was worse than first reported -- and that the man had raped them and sexually abused them in other ways, starting when they were ages 6 and 8.

That’s all according to court papers filed by the prosecution.

That information led police to interview Jonathon Paul Rogers, 33, on Dec. 19. He admitted to sexually abusing the girls and wrote an apology letter, according to a probable-cause affidavit. Police arrested and booked him into jail later that day.

A grand jury indicted Rogers on 11 counts of first-degree rape, first-degree sodomy and other charges. Under Jessica’s Law, which is meant to punish offenders who commit certain sex crimes against children under age 12, Rogers would face a minimum 25 years in prison upon conviction. But with consecutive sentences for each count, he could end up being sentenced to 100 years or more.

Rogers is being held in Multnomah County jail, with no possibility of posting bail.

Rogers told jailers he served in the military and was honorably discharged. He said he has been working full-time in private industry and is receiving some disability payments.

Rogers has no history of criminal convictions, according to court papers.
