The four reported rapes involving female students in campus housing since the fall semester began remain under investigation by Cal State San Marcos University Police, according to the San Diego Union-Tribune. The Coast News reported that the university police crime log showed no arrests by campus police in the four cases as of noon Sept. 20.
What the public alerts identified
The Coast News said it confirmed the reports through campus security alerts shared by students and authenticated by university officials. The alerts described reports dated Sept. 5 at The Quad, Sept. 6 at University Village Apartments across the street from campus, Sept. 13 at Black Oak Hall and Sept. 18 at The Quad. The Union-Tribune reported that each student described a different alleged attacker whom she knew, and that no other students witnessed the reported assaults.
University response
University spokesperson Jerry McCormick told the Union-Tribune that University Police were investigating and increasing patrols. The campus security escort service remains available to campus members who request it, the newspaper reported. The Coast News said the university disclosed the reports through timely-warning bulletins sent to currently enrolled students, faculty and staff; such notifications are associated with the federal Jeanne Clery Campus Safety Act, which requires colleges to publicly report campus-crime information and related safety policies, according to the Clery Center.
What prior reviews found
Separate reviews offer broader context but do not establish facts about the four CSUSM reports. In a June 30, 2026 review of four UC and CSU campuses—not CSUSM—the California State Auditor examined 97 sexual-harassment cases and found six with substantive issues. A limited CSU Chancellor’s Office audit dated Oct. 2, 2025, found that the rationale for not opening an investigation was not clearly documented in 14 of 37 reviewed cases; it likewise did not assess the facts of the four CSUSM reports.
Student demand for more security
A CSUSM student created a Change.org petition seeking additional security in parking lots, the Quad and other poorly lit areas, along with greater transparency about the university’s response. The petition had more than 400 signatures by late Monday, according to the Union-Tribune.
