SAN ANTONIO -

The final witness for the state in the kidnapping and rape trial of Bobby Moreno, 43, was an expert in child sexual abuse.

When asked if the victim was lying when she testified Friday that Moreno and his older brother, Juan, held her captive in their East side crack house in December 2007, Dr. Nancy Kellogg said it was possible.

“That does happen. It’s rare in my experience, based on the children that are referred to us,” Kellogg testified. “But it has happened on a few occasions.”

The victim, who was 13 at the time, testified that the brothers repeatedly raped her during two weeks of captivity and that they sold her for sex to about a dozen other men.

Prosecutors noted that the teen’s testimony tracked what she said during Juan Moreno’s trial 18 months ago.

That suggests her testimony was credible, according to Kellogg.

“Sometimes they’re vague and they cannot follow through with details when they’re making it up,” she testified.

Juan Moreno was found guilty of super aggravated assault and kidnapping and sentenced to four life prison terms without the possibility of parole.

If he is convicted, Bobby Moreno is facing the same sentence.

Closing arguments and jury deliberations are set for Tuesday in Judge Ron Rangel’s 379th District Court.
