A California mother known locally as the “Party Mom” now faces the possibility of decades behind bars after a jury found her guilty in a case that shocked her community and drew national attention.
After a three-month trial in Santa Clara County, a jury convicted 51-year-old Shannon O’Connor of 58 out of 63 felony and misdemeanor charges, according to prosecutors. The verdict could send the Los Gatos resident to prison for up to 30 years when she is sentenced.
O’Connor had pleaded not guilty in 2023 to a long list of charges that included child endangerment, sexual battery and providing alcohol to minors. Prosecutors said the case involved dozens of teenagers, including 12 juvenile girls and eight boys, who were identified in court only as “Jane Does” and “John Does.”
Authorities alleged that O’Connor hosted a series of gatherings at her home during the 2020–2021 school year, when many teenagers were isolated during COVID-19 lockdowns. According to prosecutors, the parties frequently involved underage drinking and unsafe situations for minors.
Santa Clara County District Attorney Jeff Rosen praised the teens who testified during the trial, calling their willingness to speak out critical to the case.
“There was a lot of hardship and pain and suffering,” Rosen said after the verdict. “But with the jury’s decision today, there is now justice.”
Some of the most serious convictions involve allegations tied to sexual misconduct involving intoxicated minors. Prosecutors said O’Connor was found guilty of two counts of digital sexual penetration involving a victim who was too intoxicated to consent. Additional charges stemmed from incidents in which authorities said she facilitated situations where one child assaulted another while teens were intoxicated.
Throughout the trial, prosecutors argued that O’Connor maintained unusual influence over the teenagers who attended the gatherings and often exposed them to dangerous environments. Investigators reportedly interviewed hundreds of witnesses and examined vast amounts of evidence, including phone records, jail calls, social media posts and video footage.
O’Connor’s defense team pushed back strongly against the allegations. Her attorney argued that she did not personally commit sexual acts and instead was being held responsible under legal theories that she aided or enabled behavior carried out by others.
Before the verdict, O’Connor also spoke publicly about the accusations, insisting she had become a scapegoat for teenagers’ actions.
In comments to a local newspaper last year, she acknowledged that the parties took place in her home and that alcohol was present but denied sexually abusing anyone.
“I’m not saying I’m not at all to blame,” she said. “It was my alcohol that they got drunk off of. It was my home that they were at. I feel responsible.”
However, she rejected claims that she pressured teens into sexual activity or directly participated in misconduct.
The jury ultimately sided with prosecutors after months of testimony.
For the families involved, the verdict marks the end of a long and painful legal battle that began more than four years ago. Prosecutors say the case would not have moved forward without the courage of the teenagers who came forward to describe what happened.
O’Connor remains in custody as she awaits sentencing, where a judge will decide how much time she could spend behind bars.
