SAN JOSE, Calif. — A verdict has been reached in the three-month trial of a former Los Gatos woman accused of organizing raucous alcohol-fueled parties for her teen son and his friends, which authorities say provided an unchecked setting for dangerous binge drinking and sexual assaults of intoxicated girls.

Shannon O’Connor, 51, has spent the past four-and-a-half years being held in Santa Clara County jail as her case dragged on through myriad delays, attorney changes, an ensuing criminal indictment that added more charges, and, since December, weeks of testimony from dozens of witnesses.

A notification that a verdict had been reached went out Wednesday morning. The verdict is expected to be read later in the morning.

Jurors waded through 20 felony counts covering child endangerment — including two that accused of her sexual battery by proxy in allowing reported victims to get staggeringly drunk — and 43 misdemeanor counts largely alleging that she furnished alcohol to minors over the course of more than a week of deliberations.

O’Connor did not testify in her defense, but she offered a defense of sorts when in December, during a holiday break in the trial, she contacted this news organization from the Elmwood women’s jail in Milpitas to mount a rare public defense against the criminal charges. She objected to her portrayal to that point and said she was being used as a scapegoat for teenagers’ illicit behavior and that the minors conspired to incriminate her to cover up their own misconduct.

In the Dec. 23 jail call with The Mercury News, she accepted some responsibility for the parties, but only through the lens of a concerned mother who knew about but failed to keep up with the teens’ scheming and, in hindsight, wrongly trying to keep the parties from garnering wider notice.

But O’Connor did not address, either at trial or in public, a raft of text and social-media communications between her and several girls who dated or were friends with her then-teen son and his friends who were thought to be the main beneficiaries of the parties, which occurred clandestinely either at O’Connor’s home or at far-flung cabins and lodges. Several teens who testified to a 2023 criminal grand jury and during trial recalled O’Connor routinely participating in group chats where she would effectively take the teens’ alcohol orders and have the corresponding liquor and beer available at the next gathering.

These communications dated back to her son’s middle-school years, and prosecutors portrayed O’Connor as aspiring to be a “cool mom” to bolster her son’s social standing, a bizarre pursuit that only escalated when the teens began attending Los Gatos High School.

Besides being lax about their drinking, O’Connor was said to have pried into girls’ romantic and sex lives in messages, subtly “normalizing” sex among the preteens and teens in the social circle. One teen testified that O’Connor pressured one girl into having sex with her son by warning that he could become suicidal if the girl did not sexually satisfy him.

The permissiveness and sexual encouragement manifested in anecdotes like when one of the boys recounted O’Connor being present when he drunkenly sexually penetrated a girl in a hot tub. The girl testified that she was so drunk that she was struggling to keep her head above water during the encounter. Other accusations described O’Connor as not seeming concerned when it was apparent that a drunk teen girl at the one of the parties was sexually exploited.

In the jail interview, O’Connor said the messages between her and the girls were overblown by investigators and authorities, and that she was trying to communicate with them at their level with the aim of encouraging them to be safe when they were drinking and having sex.

While O’Connor largely denied the allegations, authorities pointed to numerous instances where she participated in antics that led to many teens getting injured as a result of their inebriation. One teen recounted nearly drowning in a bathtub after a night of heavy drinking. In another incident, a teen boy reportedly suffered a serious head injury after drunkenly hanging from then falling from an SUV during a joyride in the high school parking lot with O’Connor allegedly behind the wheel.

In the latter instance, a teen recalled that she posed as the injured boy’s mother to ward off suspicion from a responding police officer, one of numerous claims of O’Connor trying to keep the whole contrivance under wraps. Besides allegedly directing teens to hide in shrubbery across the street to avoid her husband’s detection, that reportedly grew to include messages, examined and revealed by authorities, that entailed O’Connor appearing to intimidate girls she suspected of breaking the secrecy.

But despite those efforts, other parents nonetheless grew wary after teens were coming home inexplicably injured or heavily intoxicated. As that suspicion surged with open talk about her, O’Connor moved with her children to Idaho, which is where she was arrested in 2021.
