INITIAL ALERTEmail
A UO student reported that an unknown substance may have been added to their drink while attending a party at Alpha Tau Omega (ATO), 616 E 16th Ave., Friday night, Oct. 18. Upon returning to their residence, the individual felt ill and received medical assistance early Saturday, Oct. 19. It is illegal to tamper with another person's drink. This reported event is under investigation. If you have any information, contact the UO Police Department non-emergency number at 541-346-2919. Options for reporting and frequently asked questions about drugging are available at https://investigations.uoregon.edu/how-get-support. There were several incidents of alleged drugging associated with fraternity parties last spring. These were investigated and documented in a spring safety advisory. Information about university conduct actions and chapter status of fraternity and sorority organizations is available at https://dos.uoregon.edu/fsl-status.
Verbatim text of the UO Alert timely warning issued October 21, 2024, at 1:00 PM PDT by UO's Division of Safety and Risk Services, confirmed from Google-indexed content of the official archive URL
Unlike an immediate-threat emergency notification, this is a Clery timely warning — issued three days after the reported incident to put the community on notice of a continuing concern and to prompt protective behavior
The warning identifies the specific address 616 E 16th Ave. (ATO's address) — but a subsequent October 23 update corrected the party location to 594 E 16th Ave., while maintaining the ATO host connection
The third paragraph links to the spring 2024 drugging investigations, providing institutional context for repeat concern — an element the prior reconstruction had missed
UPDATEEmail
Investigation update: The October 18 party associated with the report of possible drink tampering occurred at 594 E 16th Ave., not at the fraternity chapter house, but was hosted by Alpha Tau Omega members. A second report of possible drink tampering has been received from a student who attended several events on October 18. The investigation continues.

This text has been reconstructed from news coverage and may not reflect the exact original wording.

The October 23 update corrected the location of the October 18 party to 594 E 16th Ave. while keeping the Alpha Tau Omega host connection, and disclosed a second possible drink-tampering report; the wording is reconstructed from Daily Emerald coverage and is marked unconfirmed.
This is an update rather than an all-clear: it expanded the scope to a second report and kept the investigation open ahead of Halloween weekend.
Coverage by OPB later criticized UO's broader pattern of delayed drugging notifications during 2024, providing important context for why this timely warning drew scrutiny.
Context

Background

The reported drugging came during a fall 2024 stretch in which the University of Oregon faced scrutiny over how quickly it warned students about drink-tampering at fraternity parties. A student reported a possible drugging at an Alpha Tau Omega party on October 18, and UO's Division of Safety and Risk Services issued a timely warning on October 21 at 1 p.m.. A second report of possible drink tampering soon followed, and KEZI reported UOPD was investigating two separate drugging incidents ahead of Halloween weekend. Separately, OPB reported that UO had failed earlier in 2024 to alert students about campus druggings in a timely manner, in apparent violation of its own protocols — context that made this fall 2024 timely warning especially significant. The case is a clean example of a Greek-life safety concern handled as a Clery timely warning rather than an emergency notification.
Analysis

Key Findings

UO issued a Clery timely warning on October 21, 2024 at 1 p.m. about a reported drugging at an Alpha Tau Omega party
An October 23 update relocated the October 18 party off the chapter house while keeping the ATO host connection and disclosed a second drink-tampering report
The warnings came amid scrutiny of UO's earlier 2024 failures to notify students of campus druggings in a timely manner
The notifications were timely warnings about a continuing concern, not immediate-threat emergency notifications
Outcome
An October 23 investigation update clarified the October 18 party occurred at 594 E 16th Ave., not at the chapter house, but was hosted by Alpha Tau Omega members. UO Police investigated two separate possible drink-tampering reports. Anyone with information was urged to call UOPD's non-emergency line.
