Sheriff’s detectives have arrested a Studio City man on multiple felony sexual assault charges stemming from an incident at a fraternity party in Isla Vista earlier this year. In April 2025, detectives began investigating a report of sexual assault that occurred at a wedding-themed party at a fraternity house in the 6500-block of Cordoba Road. Through their investigation, detectives identified the suspect as 19-year-old Reef Mordente of Studio City. As part of the extensive follow-up in this case, investigators uncovered conversations using language that framed the assault in “scoring” or “conquering” terms.

On Saturday, August 9, 2025, Mordente surrendered to the Los Angeles Police Department, where he was arrested on a felony warrant for rape of an intoxicated victim, forced oral copulation, and digital penetration. Mordente was booked and released on $100,000 bail.

Sheriff’s detectives believe there were witnesses to this assault who have not yet come forward. We want to emphasize the seriousness of these crimes and the lasting trauma they cause survivors. Coming forward can be difficult, but it is essential in helping ensure accountability, preventing future harm, and supporting survivors in their healing process. Anyone with information related to this case is strongly encouraged to contact Detective Ellis at (805)681-4150. If you would like to be anonymous, you can submit information online at: sbsheriff.org/home/anonymous-tip or by calling (805)681-4171.

The Sheriff’s Office also partners with Standing Together to End Sexual Assault (STESA) to provide support for survivors and to address cultural factors that perpetuate sexual violence. STESA Executive Director Elsa Granados shared:

“Our prevention efforts must prioritize the vast majority of men—those who may never engage in criminal behavior themselves, yet whose participation in peer groups and social dynamics can, knowingly or not, enable sexual predators. Through laughter at inappropriate jokes or uncritical acceptance of stories framed as ‘conquests’ or ‘scores,’ men may become passive bystanders or inadvertent facilitators of harm.

Men also have a vital role in supporting survivors and acknowledging the ripple effects of sexual violence—including the trauma endured by victims and the consequences faced by perpetrators as they enter the criminal justice system. Addressing these issues requires collective responsibility, empathy, and a commitment to cultural change.”

The Sheriff’s Office remains committed to thoroughly investigating these cases, working alongside advocacy partners, and ensuring that survivors have access to resources and support. Sheriff’s detectives coordinate closely with the Santa Barbara County District Attorney’s Office, Victim-Witness Program to ensure the needs of survivors are not overshadowed by the focus on the investigation and prosecution of the accused. Victim Advocates are available to ensure that survivors are kept informed and supported throughout the criminal justice process. Survivors have the option of contacting the Victim-Witness Assistance Program directly at (805)568-2400 or toll free at (855)840-3232.

The Sheriff’s Office would like to remind survivors that they can also find support services through our community partner, Standing Together to End Sexual Assault (STESA). Services offered by STESA include a confidential 24-Hour hotline, legal and medical advocacy and accompaniment, and counseling. You can reach a STESA advocate at any time by calling (805)564-3696.
