SAN JOSE, Calif. — Jurors are now deliberating 63 felony and misdemeanor charges against a former Los Gatos woman accused of masterminding pandemic-era sex-and-alcohol-filled parties for her teen son and friends, which authorities and other parents allege enabled girls to be sexually assaulted while inebriated.

Shannon O’Connor, 51, did not testify in her defense during the trial, which began in earnest Dec. 1 and included testimony from former teens who attended the infamous parties.

A jury was handed the case Tuesday, with several days of deliberation expected, at minimum, as they sort through reams of information and evaluate the individual charges. Twenty of the counts cover alleged felonies for child endangerment and aiding and abetting sexual assault, and 43 misdemeanor counts related to furnishing alcohol to minors.

Prosecutors contend that the alleged crimes stemmed from O’Connor’s desire to bolster her son’s social status at school, including cultivating a reputation as a “cool mom” who allowed him and his friends to drink alcohol at her Los Gatos home as early as their middle-school years. Once her son entered Los Gatos High School, they allege, both the size of the parties and O’Connor’s role in encouraging sexual activity between underage boys and girls escalated.

One teen recounted nearly drowning in a bathtub after a night of heavy drinking, and several recalled having little to no memory of being sexually penetrated. In one instance, a teenage boy reportedly suffered a serious head injury after falling from an SUV during a drunken joyride in the high school parking lot with O’Connor behind the wheel.

O’Connor was also accused of aggressively trying to secure the attendees’ silence about the parties, which were held at her home and on a few occasions at out-of-area lodges and cabins. But the parties, injuries, and reputed sexual assaults garnered attention from other parents, and as suspicion about O’Connor surged she moved with her children to Idaho, where she was arrested in 2021.

While O’Connor did not testify at trial, in late December, she contacted this news organization from the Elmwood women’s jail in Milpitas to object to how she had been portrayed, and positioned herself as a scapegoat for teenagers’ illicit behavior. She pointed to the teens being granted immunity by the prosecution as proof of their plan to pin the scandal on her.

She did take some responsibility for the parties, but only as what she characterized as a “concerned mother” who was trying but failing to keep up with their scheming, including routine raids of their parents’ liquor cabinets.

“Teenagers are sneaky. They find their way to things,” she said during the Dec. 23 phone call. “They were punished and grounded on numerous occasions, but they still got into it, and there was really no stopping it.”

One parent whose daughter is on the prosecution’s list of victims responded to O’Connor’s defense as an example of her being “a master manipulator,” and said the evidence of her crimes is indisputable given the bevy of social-media messages and text messages between her and the teens revealed by other parents and investigators, which detailed the defendant coordinating alcohol orders and probing their sex lives.

“I knew that these kids were drinking. I knew these kids were having sexual relations, whatever that may be. I was trying to make sure that they were being safe,” O’Connor said in December. “People can look at that a few different ways.”

In April 2023, O’Connor explored a potential guilty plea but withdrew after Judge Elizabeth Peterson told her the resulting sentence would be 17 years in prison. Six months later, prosecutors secured a criminal grand jury indictment that increased the charges from the 39 in the original criminal complaint to 63, and raised her potential maximum sentence to more than 30 years.

A major sticking point with O’Connor has been her aversion to the possibility of having to register as a sex offender after the indictment added two felony sexual penetration charges. Those counts accuse her, by proxy, of aiding in the sexual assault of two girls by virtue of facilitating their intoxication and thus impairing their ability to consent.
