Jury finds Los Gatos 'Party Mom' guilty on most underage drinking, sex counts

A Santa Clara County jury on Wednesday returned mostly guilty verdicts in the case of "Party Mom" Shannon O'Connor, a Los Gatos mom accused of hosting parties for underage teens that included alcohol and sexual conduct.

Mostly guilty verdicts

What they're saying:

There were five not guilty results.

But the jury found that O'Connor was guilty on the majority of more than 60 charges against her, including child endangerment and the sexual penetration of an intoxicated child-- the most serious of the charges. There were more than a dozen victims. 

After the verdicts were read, the parent of one of the victims called O'Connor a "predator," a "stalker," a "groomer" and a "harasser" who was "very good at what she did." 

"After many years and many, many victims, today there was justice," Santa Clara County District Attorney Jeff Rosen told reporters outside court. "It was a long wait. It was a long trial. There was a lot of hardship, pain and suffering, but with the jury's verdict, today, there is now justice."

He thanked the child victims in the case for coming forward, and blamed O'Connor for being a parent herself for taking advantage of children. 

O'Connor's defense attorney, Stephen Prekoski, spoke, too.

He said he felt the jury was diligent in their verdicts, but obviously, he wasn't pleased. 

"This is a disappointing verdict," Prekoski told reporters outside the courthouse. "It's not the result we were hoping for." 

The jury began deliberating on Feb. 24 at the San Jose Hall of Justice. The trial lasted about four months. 

Underage alcohol, sex parties 

Why you should care:

The 51-year-old O'Connor faced 63 criminal counts, including felony sex offenses and misdemeanors, related to hosting parties with alcohol and allowing underage teens to drink and engage in sexual conduct.

Prosecutors spoke with some 13 students, who said O'Connor invited them to her Los Gatos home and encouraged the teens and her son to drink alcohol and engage in sexual activity. 

The teens said she tried to hide the parties from her husband and neighbors. Prosecutors said O'Connor hosted the parties between 2021 and 2022. Some of the students said they were victims of sexual misconduct.

The backstory:

O'Connor did not testify in her defense, the Mercury News noted. 

But she did call the news organization on Dec. 23, 2025, from call, where she told the Mercury News that she accepted some responsibility for the parties, but only through the lens of a concerned mother and was trying to communicate with the teens at their level, trying to encourage them to be safe when they were drinking and having sex.

A legal expert noted Prekoski did not contest some accusations that O'Connor used bad judgment in supplying alcohol to underage teens, but instead, focused on the felony sex charges.

O’Connor was arrested in 2021 in Ada County, Idaho, where she was living at the time. She was brought back to Santa Clara County jail, where she has been held ever since.

These convictions will also require O’Connor to register as a sex offender.
