SAN DIEGO -- A judge, citing juror misconduct, declared a mistrial Tuesday in the case of a former fifth-grade teacher accused of molesting two boys once in her class.

Adrienne Feistel, 36, will be retried next year, Judge Richard Whitney said. If convicted of all charges, she could face 30 years and eight months in prison.

After deliberating for parts of four days, jurors passed a note to the judge indicating they were deadlocked on 14 of 17 charges against the defendant.

The jury had reached verdicts on three counts, which were sealed as deliberations continued.

On Tuesday, the judge revealed that one juror had watched media coverage of the case and told other jurors.

A number of jurors also complained that a fellow panelist told them that she would decide the case by her heart, no matter what the evidence showed.

Whitney found jury misconduct in both instances and also struck the three verdicts that had been reached.

Prosecutor Wendy Patrick alleged in her opening statement that Feistel -- a teacher at Rosa Parks Elementary School in City Heights -- became close to the victims' families before molesting their children.

The defendant had become best friends with the 16-year-old sister of a 12-year-old boy before she began molesting him in 2006, the prosecutor alleged.

She said Feistel complained that the boy wasn't paying enough attention to her, then moved in with his family when she separated from her husband.

The boy, now 15, testified that Feistel came into his room at night and molested him.

He said the first time Feistel got in bed with him, she kissed him, and that during a third late-night visit, Feistel touched his "privates." He said she told him her mouth would "feel good" on his privates, and during another visit she orally copulated him.

He said she also asked him to put his mouth on her breast, which he did, but that he refused her request for intercourse.

Feistel had to move out after his mother came in his room one morning and caught them in bed together, the teen said.

He said he told three friends about Feistel but didn't tell any adults until August 2008, when police were called to his home to break up an argument between his mother and sister.

The other alleged victim said he had sex with Feistel before he turned 18, Patrick said.

Defense attorney Anna Yum told the jury in her opening statement that the younger boy's mother falsely accused Feistel of molesting her son to protect herself and regain control of her relationship with her older daughter.

The day of the mother-daughter argument, the daughter called Feistel to "save me from my abusive mother," Yum told the jury.

The attorney urged jurors to assess the credibility of witnesses, and asserted their testimony was based on "gossip and innuendo."

Yum said the other alleged victim never once said he was under 18 when he had sex with Feistel, and that there was a lack of credible evidence to prove her client guilty.
