Clyde Ezra Turner, who helped coach Pasadena's John Muir High School track team to five state championships, was sentenced Monday to three years in prison for molesting a 15-year-old athlete.

Pasadena Municipal Judge Mary Thornton House handed down the sentence after the boy's father said Turner had betrayed the family and was a pedophile who "spewed a web of deception" to lure boys to his home.

"He committed his disgusting, lewd act, pouncing on [my son] like he was the kill of the hunt," the boy's father said. "Balance the scales of justice."

Thornton House said the 44-year-old Turner, onetime national track coach of the year, had been a revered community leader who violated that trust and deserved prison time.

"There is a strong likelihood the defendant would continue to victimize other minors," the judge said, quoting from the coach's probation report.

Turner was sentenced to three years for committing a lewd act upon a child and eight months for exhibiting pornography to a minor, but the terms were ordered to be served concurrently. Turner was credited with 183 days served in jail. He also was ordered to register as a sex offender, pay a $200 fine and undergo testing for AIDS.

Dressed in a blue jail jumpsuit with his hair in a ponytail, Turner rocked silently in his chair, jingling his handcuffs and watching reporters. Gone were the smiles of earlier proceedings.

Turner was convicted in May after a seven-day trial, in which the 15-year-old boy testified that he had watched a pornographic video in the coach's bedroom in April 1998 and that the coach then molested him.

Another student testified that he saw a pornographic cable program in December 1997 while sitting on Turner's bed, and that the coach twice pushed him down on the bed.

The jury deadlocked on a second felony count of exhibiting pornography to that youth and a misdemeanor charge of child annoying. Prosecutors decided Monday not to retry Turner on those charges.

Jurors also heard from three former students who alleged that Turner molested them more than 15 years ago. The judge let them testify under a controversial 1996 law that allows prosecutors to use such material to show that a defendant is predisposed to sex crimes.

Before sentencing, attorney W. Anthony Willoughby asked unsuccessfully for a new trial, saying that testimony violated his client's constitutional rights. He cited two appellate court decisions in similar cases.
