Shannon Marie O'Connor, dubbed the 'party mom' by prosecutors, has been convicted on multiple charges related to hosting alcohol-fueled parties for teens where sexual acts occurred. The jury found her guilty of more than 40 counts, including child endangerment and misdemeanor sexual battery.

O'Connor, a 51-year-old former resident of Los Gatos, was accused of staging at least six such parties in 2020 and 2021. Prosecutors alleged that she provided alcohol to minors, encouraged them to drink to the point of unconsciousness, and facilitated sexual acts among the teens. The charges stem from incidents where O'Connor allegedly handed condoms to intoxicated teens and pushed them into rooms together.

Santa Clara County District Attorney Jeff Rosen stated that O'Connor's actions caused significant harm to many victims over several years. 'This defendant took advantage of children, manipulated children, hurt children emotionally, mentally, physically and did that for her own perverse reasons,' Rosen said at a briefing Wednesday afternoon.

O'Connor's attorney, Stephen Prekoski, expressed disappointment with the verdict but acknowledged the jury's decision. 'Obviously, not the result we were hoping for,' Prekoski said. He suggested that the defense might appeal, arguing that O'Connor's role in the sexual assaults was not direct enough to warrant conviction.

The case gained significant attention due to its disturbing nature and the number of victims involved. Prosecutors presented testimony from 41 witnesses, including 20 young adults who attended the parties. The jury deliberated for several days before reaching a verdict.

O'Connor is scheduled to be sentenced on March 26 and faces more than 30 years in prison. At the sentencing hearing, victims will have the opportunity to make impact statements, and O'Connor will also be allowed to speak. The case highlights the severe consequences of adult facilitation of underage drinking and sexual activity.
