A Devore doctor, Jay Howard Tibbles, admits that he tried to find a young girl online.

SAN BERNARDINO - A Devore pediatrician could serve up to one year in jail and will be supervised while around young children or the Internet after pleading guilty Friday to searching online for a young girl to be his sex slave.

Jay Howard Tibbles, 57, reached a plea agreement with prosecutors and pleaded guilty to 11 counts of lewd or lascivious acts involving children, court officials said.

According to the plea agreement, Tibbles could serve up to one year in the West Valley Detention Center when he is sentenced Dec. 21.

San Bernardino County Superior Court Judge Ronald Christianson will decide how much jail time Tibbles will do, based in part on a recommendation from the county probation department.

Tibbles will have to be supervised by a "responsible adult" when he is around children under age 18 or using the Internet. The adult supervisor must be made aware of Tibbles' guilty pleas in the current case, under the agreement.

He also will have to complete a sex-offender treatment program and not possess any legally obscene material, officials said.

Tibbles, who remains free after posting $400,000 bail, was arrested in December after he contacted a woman he had met in an Internet chat room. He thought the woman was the mother of a 12-year-old girl, investigators said.

The woman actually was an undercover officer patrolling the Internet in search of illegal activity. There was no young girl and no one was victimized by Tibbles, officials said.

Tibbles proposed meeting the girl for sex acts with him. After several computer and telephone messages were exchanged, he agreed to meet the girl and was arrested.

Tibbles was placed on paid administrative leave from his job at Kaiser Permanente Medical Center in Fontana after his arrest. How the guilty pleas will affect that job status was not clear Friday...
