SAN JOSE — A judge has increased the potential prison sentence for a former Los Gatos mother convicted of more than a dozen felonies for orchestrating raucous teen parties scandalized by binge drinking and sexual assaults, after ruling that she preyed on vulnerable children and should be exposed to harsher penalties.
Santa Clara County Superior Court Judge Elizabeth Peterson announced Wednesday that she found true multiple aggravating factors for Shannon O’Connor’s 16 felony convictions, composed of 13 child endangerment counts, two sexual penetration counts and one count of dissuading a witness. The finding gives the judge the option of sentencing O’Connor to the maximum term at a hearing later this month.

O’Connor, 51, was convicted by a jury last week of the felonies along with 31 misdemeanors encompassing child endangerment and furnishing alcohol to minors after a three-month trial. She did not appear in court at a hearing Wednesday, but Peterson went ahead with her rulings on so-called sentencing aggravators accompanying the felony counts.
Peterson decided that in all of O’Connor’s felony convictions she exploited a position of trust and targeted vulnerable victims. In 11 of the child endangerment counts and the two sexual penetration counts, she exhibited planning and sophistication in the crimes, the judge ruled.
O’Connor was also found to have induced a minor to commit a crime for the two sex counts, which were based on allegations that she facilitated the sexual penetration of two girls by enabling them to become too intoxicated to consent. Witnesses testified that O’Connor either encouraged or summarily dismissed claims about boys committing sex acts on the inebriated victims.
“Today’s ruling confirms what the parents and victims in the Los Gatos community came to know all too well – that Shannon O’Connor put herself in a position of trust over the well being of kids, and she abused that trust. Ms. O’Connor’s planned actions took advantage of the vulnerability of the innocent she drew to her home over years,” District Attorney Jeff Rosen said in a statement Wednesday. “The kids in our community are all of our kids, and we owe them our best. Ms. O’Connor turned that value on its head and treated the kids in our community as targets for abuse.”
In a brief phone call, O’Connor’s attorney, Stephen Prekoski, told this news organization the judge’s ruling “was not a surprise,” but refrained from further comment until after his client’s sentencing, currently scheduled for a March 26 court hearing.
The net effect of the aggravators being found true is that Peterson now has the discretion to issue maximum terms for each of O’Connor’s felony convictions. If the judge were to enforce consecutive sentences on just the felonies alone, her sentencing range spans from 33 years in prison to a theoretical — though highly unlikely — term nearly three times as long.
But given Peterson’s wide discretion to set any number of the sentences concurrently, including on the misdemeanor convictions, any estimate for what she could hand out to O’Connor would be largely guesswork. One certainty is that because of the sexual assault convictions, O’Connor will be required to register as a sex offender with the state; Prekoski maintains she did not commit a sexual assault and continues to question the theory used for those charges.
O’Connor has been in Santa Clara County jail custody since October 2021, after she was arrested near Boise, Idaho. She moved there with her two children as other Los Gatos parents, and authorities, grew suspicious of the pandemic-era parties at her home and far-flung locations like lodges in Santa Cruz and Lake Tahoe.
As the criminal case progressed, a portrait of O’Connor began to take form through the accounts of teens who attended the parties, including a huge volume of text messages and Snapchat messages in which she was shown to have facilitated the teen gatherings, taken their alcohol orders, and pried into the personal and sex lives of girls attending the parties. Those included girls who dated her teen son or his friends.
The communications dated back to her son’s middle-school years; prosecutors described O’Connor as adopting the persona of “cool mom” to bolster her son’s social standing, which escalated when the teens began attending Los Gatos High School. O’Connor was later accused of “normalizing” sex among the preteens and teens in the social circle. One teen testified that O’Connor pressured a girl to have sex with her son by warning that he could become suicidal if she refused.
O’Connor did not testify in her defense, and Prekoski focused his arguments on fighting the proxy sexual assault claims against her.
But on Dec. 23, in the middle of the trial, O’Connor called this news organization to push back on her public portrayal and claim she was being scapegoated for the teens’ illegal behavior. During the phone call from jail custody, she acknowledged having some responsibility for the parties, but framed herself as a concerned mother who tried to stop the behavior but failed to adequately intervene.
Ultimately, jurors sided with prosecutors whose 2023 criminal indictment outlined numerous instances of teens getting injured as a result of their inebriation under her watch.
In the instance that fueled the witness-dissuasion conviction, a teen boy reportedly suffered a serious head injury after drunkenly hanging from an SUV then falling during a joyride in the high school parking lot. As a responding police officer caught up to them, O’Connor reportedly told the injured boy to stay silent then posed as his mother to ward off suspicion.
