ANTIOCH, Calif. (CBS/AP) Phillip Garrido's unspeakable private life began unraveling in a very public place: a college campus.

He arrived Aug. 24, at the police office at the University of California, Berkeley, with two girls, ages 11 and 15. He announced he wanted to hold a religious event on campus related to a group called God's Desire. He seemed weird and unstable. But it was the pale, blonde, blue-eyed girls in drab dresses who really set off alarm bells.

"There were some things about him and the kids that were really alarming, that just didn't settle right with me," said Lisa Campbell, the department's manager of special events, who previously worked as a police officer in Chicago and a background investigator for the Los Angeles Police Department.

So she arranged another meeting for the next day, and called upon officer Ally Jacobs to join her. Jacobs ran a records check — and discovered that Garrido was a registered sex offender who had been convicted of rape and kidnapping more than 30 years ago.

The girls unnerved Jacobs, as well. They seemed programmed — "almost like `Little House on the Prairie' meets robots," she says.

The younger girl "was staring directly at me," says Jacobs, the mother of two small boys. "It was almost like she was looking into my soul. ... Her eyes were so penetrating."

When Jacobs asked her about a bump near her eye, "she immediately replied with this very rehearsed response: `It's a birth defect ... I'll have it for the rest of my life.'

"I was a little taken aback. ... She just wouldn't stop smiling."

The older daughter, meanwhile, stared at the ceiling and looked at her father "in awe, as if she were in worship of him. I kind of got the feeling that these kids were like robots."

Garrido gave them copies of his book he had written called "Origin of Schizophrenia Revealed." They had a hard time following his conversation.

But he revealed the girls were home-schooled by his wife, with an assist from him. The girls said they had an older sister at home, 28 or 29, and that seemed strange, too, that she was even mentioned.

Finally, Jacobs says, Garrido grabbed his oldest daughter and said: "'I'm so proud of my girls. They don't know any curse words. We raised them right. They don't know anything bad about the world."'

By then, she says, "my police mode turned into my mother mode."

A call was made to Garrido's parole officer. A terrible secret was about to be revealed.
