Santa Rosa Police Seek Additional Victims Following Serial Assault Arrest

• Santa Rosa Police arrested 28-year-old Koa Brooks on July 29.
• Brooks faces charges including rape by force and felony assault.
• Investigators believe he used social media and the alias Ty to contact victims.
• Detectives are actively searching for additional unreported victims.

Santa Rosa law enforcement officials have launched a broad investigation following the arrest of a local man suspected of committing multiple violent sexual assaults. The Santa Rosa Police Department's Domestic Violence Sexual Assault Team took Koa Brooks into custody on July 29, 2026, sparking an urgent appeal for public assistance.

Arrest Details and Criminal Charges

Authorities charged Brooks with several serious offenses, including rape by force, rape of an intoxicated person, and felony assault likely to cause great bodily injury or death. Initial interviews with cooperating individuals revealed a pattern of predatory behavior that prompted detectives to expand their outreach beyond the initial reports.

Online Outreach and Suspected Alias

According to police statements, Brooks allegedly initiated contact with potential targets through social media platforms. Investigators noted that the suspect may have operated under the alias Ty or a variation thereof. Law enforcement officials are urging anyone who interacted with this account to come forward immediately.

Local California Context

This case highlights the critical role of specialized units within California municipal departments. The Santa Rosa Police Domestic Violence Sexual Assault Team handles complex investigations requiring sensitive victim coordination and forensic analysis. Community members in Sonoma County are encouraged to review recent online interactions and report any suspicious activity matching the described profile.

These efforts occur against a backdrop of heightened regional scrutiny regarding sexual misconduct, including the ongoing civil trial of former Windsor Mayor Dominic Foppoli. Facing allegations from seven women spanning more than two decades, Foppoli recently underwent cross-examination by plaintiff attorney Traci Carrillo. According to the Press Democrat, Foppoli repeatedly denied all allegations of nonconsensual sex during the proceedings, asserting that the encounters were consensual and expressing frustration over what he termed false stories. The atmosphere grew tense as Carrillo pressed him on accusations of coercing women, disregarding personal boundaries, and allegedly manipulating victims who were in their late teens at the time. Although the California Attorney General previously determined there was insufficient evidence for criminal prosecution, the civil proceedings have prompted renewed community dialogue about accountability and survivor support mechanisms across the county.

Investigation Background

Sexual violence investigations frequently uncover additional incidents long after the initial arrest. Historical data shows that perpetrators often operate across extended timelines, relying on victim hesitation or fear to delay reporting. The department emphasized that trained advocates are available to guide survivors through legal options while maintaining strict confidentiality.
