HAPPY VALLEY, Ore- It's the type of conference that had to begin with a warning for those in the audience. Hearing from victims of sexual abuse is hard enough, but hearing from the predators themselves is enough to make your skin crawl.

Cory Jewel Jensen with the Center for Behavioral Intervention says one in five girls and one in ten boys will be sexually abused before they turn 18. So she is trying a new approach.

She's interviewing the predators to learn how they pick their victims and how they go unnoticed. She says parents don't realize who the bad guys really are.

"Parents are relying on stranger danger which while that's important that's not the most common relationship in which kids are abused. The more likely scenario is it's going to involve a family member or family friend," Jewell Jensen said.

No one knows that better than Randy Ellison.

"I was a victim of my youth pastor from age 15 until I turned 18," Ellison said.

Ellison says his own church pastor abused him for years, and no one suspected a thing.

"The stress is toxic so the release is coming home from work and getting high on drugs and alcohol," Ellison said.

It took him four decades to come to terms with what happened. Years later he's written a book and started a non-profit to help other victims of abuse. He's hoping parents learn from what Jewell Jensen has to say so other kids don't face the type of abuse he did.
