INITIAL ALERTEmail
Clery Timely Warning -- Sexual Assault | 9-12-24 The ASU Police Department received a report of a Sexual Assault which occurred on the evening of September 11, 2024 at a residential housing complex located on the south side of the Tempe campus. The suspect was in the victim's room with others. After the others left, the suspect assaulted the victim. The suspect was known to the victim and no arrest has been made. If you have information about this incident, please contact the ASU Police Department at 480-965-3456.
The narrative 'suspect was in the victim's room with others; after the others left, the suspect assaulted the victim' describes a classic bystander-departure assault pattern -- an important scenario for community safety education
ASU maintains a well-organized Clery timely warning archive at cfo.asu.edu where each incident is published on a dedicated URL -- a model transparency practice
The 'suspect was known to the victim' disclosure indicates no stranger is at large while still triggering mandatory timely warning issuance, consistent with Clery Act requirements
ASU's Tempe campus, with approximately 59,000 on-campus and surrounding students, is one of the largest single campuses in the United States, making the Clery geography and notification reach substantial
Context

Background

Arizona State University operates one of the largest Clery Act timely warning archives in the country at cfo.asu.edu/clery-timely-warning, where every qualifying incident is published on a dedicated, date-stamped URL. On the evening of September 11, 2024, a sexual assault occurred in a residential housing complex on the south side of the Tempe campus. The suspect was an acquaintance who had been in the victim's room with a group; when the others departed, he committed the assault. ASU Police received the report on September 12, 2024 and posted the Clery timely warning the same day. The incident occurred during the first weeks of the fall semester -- within the campus safety research period known as the Red Zone -- when first-year students face elevated sexual assault risk. ASU's transparent, URL-per-incident archive approach contrasts with many institutions that publish only aggregate statistics or bury timely warnings in generic alert feeds, and the Tempe campus has been the subject of federal Clery Act review in prior years.
Analysis

Key Findings

ASU maintains a model Clery timely warning archive with a unique URL per incident -- a best practice in campus safety transparency that makes longitudinal research possible
The assault pattern described (acquaintance in the room with a group; others depart; assault occurs) is a common scenario identified in campus sexual assault research and bystander intervention curricula
The incident fell within the Red Zone -- the first weeks of the fall semester -- consistent with national data showing elevated sexual assault risk in early September
ASU has faced federal Clery Act scrutiny in prior years, making its public-facing timely warning archive both a legal obligation and a reputational investment
Outcome
Investigation ongoing at time of timely warning. Suspect was known to the victim. No public arrest reported.
