Three teens facing charges in the sexual assault of a 15-year-old Northern California girl who committed suicide after the attack appeared in court for the first time Tuesday.

The proceedings were not public, and lawyers involved in the case aren’t commenting.

The three 16-year-old boys are each charged with sexual battery, dissemination of child pornography and possession of child pornography.

Attorneys and family members of the defendants were seen entering juvenile court. Relatives of Audrie Pott, who killed herself after a humiliating photo of her on the night of the attack circulated, were also there.

Santa Clara County Deputy District Attorney Jaron Shipp told The Associated Press that he couldn’t comment or provide any information on the case because the boys are juveniles.

The Motion Picture Association of America is changing its rating system to better inform parents about violence in movies.

CEO Christopher Dodd announced the tweaks in Las Vegas Tuesday at the annual movie-theater convention, CinemaCon.

The White House has called on the movie industry to give parents better tools to monitor violence in media since the Newtown, Conn., school shooting.

Dodd did not address the shooting directly but spoke generally about the need to help parents control what their kids see.

The new ratings system will include descriptions about why a movie received its ratings.

For example, the rating might cite “strong carnage” or “war violence.”

Prosecutors say a Wisconsin man who has admitted he killed his three young daughters was in control of his actions and decided that a “selfish desire for revenge” was worth more than his girls’ lives.

Jurors are weighing whether Aaron Schaffhausen was legally sane when he killed 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia in their River Falls home last July.

During closing arguments Tuesday, prosecutor Gary Freyberg told jurors that Schaffhausen was in control of his actions, and that he is a mean, callous person — but not legally insane.

Defense attorney John Kucinski said earlier that Schaffhausen has a rare mental disorder, rooted in a deep dependency on his wife.

Schaffhausen has pleaded guilty to three counts of first-degree intentional homicide, but he maintains he’s not responsible.

The director of the Omaha Marathon says the bombing in Boston will make her more vigilant about security, but she doubts it will diminish the popularity of marathons.

Director Susie Smisek said Tuesday security for the Omaha race generally has been focused on keeping runners safe from vehicle traffic. She said other security threats will now get more scrutiny when the marathon is held Sept. 22.

Smisek said it will be important to “watch out for something that might not look right.”

Smisek said marathons have increased in popularity in recent years because more people are health conscious.

She said Boston will continue to be on runners’ minds for a while but that participation in marathons probably won’t decline.

The next marathon in Nebraska is May 5 in Lincoln.
