SACRAMENTO (CBS13) – After months of delays, the former Citrus Heights principal accused of molesting his own students faced a judge in his preliminary hearing.

With his wife and daughters by his side, Robert Adams faced a Sacramento Superior Court judge, listening as an investigator testified about how one of his alleged young victims reacted when she saw her principal’s picture in a yearbook.

“I want to tear up all these pictures of Mr. Bob. I want to kill him. I just want to stab him. I want to make him go away,” the investigator said.

The prosecution called several investigators to the stand Thursday in Adams’ preliminary hearing. They testified they’d gotten reports over the years from several girls who accused the man of touching them while on campus of his now-shuttered private school Creative Frontiers.

“Mr. Bob was rubbing her tummy or stomach and had subsequently touched her pee-pee,” said another investigator said.

Adams’ attorney revealed what may be a key point in his defense if the case goes to trial.

Linda Parisi said two mothers, whose daughters are alleged victims, were late in paying tuition. Parisi says they had received notices just before their calls to 9-1-1 to report the alleged child molestation.

“I certainly think there’s information that raises a question about the motivation of these parents,” she said.
