Following an investigation into allegations of hazing, neutral case managers found that the Delta Sigma Phi fraternity engaged in hazing behavior including forced consumption of onions, milk and alcohol and planking on broken glass, according to public records obtained by The Daily Emerald.

D Sig was disaffiliated through winter 2030 on Feb. 27 following the conclusion of the investigation into the fraternity’s hazing allegations. It had previously been placed on interim suspension on Nov. 7, 2025 after the UO Police Department received a hazing report, which then prompted a report by the Dean of Students Office.

A Notice of Allegations letter, sent to the fraternity by the Office of the Dean of Students on behalf of Student Conduct and Community Standards, detailed the witness accounts and how those were taken into account by the neutral case managers to come to the final decision. Upon disaffiliation, the university stated that D Sig had violated the following university policies: hazing, safety hazard, theft, alcohol and retaliation or obstruction.

Documents from the investigation obtained by The Emerald include witness accounts and evidence that substantiates each policy the fraternity was found to have violated. OSCCS stated in its investigations that, reportedly, the hazing behavior occurred in October and November 2025 and included, but was not limited to, the forced pressure to consume milk, onions and alcohol, purchase snacks for older members at night, plank on broken glass, clean vomit and allow older members to spit and blow cigarette smoke in the faces of new members.

It is noted in the report that members of the chapter reportedly communicated with an individual involved with reporting the hazing allegations, attempting to deter them from reporting.

Additionally, the report found that new members were allegedly furnished with alcohol during the noted hazing activities or at social events, and surveillance images show members of the chapter attempting to use a ladder to steal items from another fraternity the day after the interim suspension was enacted.

Witness accounts

Eight witnesses were interviewed in total about the hazing allegations, according to the documents. Neutral case managers oversaw the interview process. According to the documents, interviewees were informed that the process was “private but not confidential” and that the D Sig president would have access to the report and interviewees would be identified by name in the report. Interviews were completely voluntary and questions could be declined.

Screenshots of text messages in the documents supported evidence that a member of the fraternity contacted Witness One after his hazing report. In these messages, Witness One describes being “harassed” by members of the fraternity.

The case managers found insufficient evidence that new and active members of D Sig were instructed to retaliate against Witness One on online anonymous platforms, but it was noted within the report that members of the chapter engaged in communication with the individual to deter them from reporting the fraternity at all.

Witness One reported that punishments would take place if a mistake was made during an event, given out by an individual called “The Prophet.” Screenshots provided by Witness One from a conversation between himself and “The Prophet” corroborate that he sustained a cut while planking on broken glass.

In the messages, “The Prophet” accuses Witness One of “leaking information” about the fraternity. Witness One responds that someone had asked him how he got the cut. The report goes on to say that the injury was serious enough to require stitches.

Because another source, likely a member of the fraternity’s executive board, confirmed to the case managers that the witness was injured, the report found the other witnesses’ lack of knowledge about the incident to “weigh against the reliability of their recollection” because all of the interviewees were all members of Witness One’s pledge class.

“The Prophet” was identified by Witness One as a non-student who could “do anything to new members and not get in trouble” and would conceal their identity to new members. According to Witness One, “The Prophet” would conduct hazing in the presence of every member of the fraternity’s executive board and acted as a “pledge master.”

Additional text message screenshots provided to Dianne Tanjuaquio, the senior associate dean of students, during a meeting show “The Prophet” telling Witness One when he could and could not attend events later that day. The messages also show that he was “disappointed” in the witness for failing to memorize a Quizlet, a popular online study tool, containing information about fellow members of the fraternity.

According to the report, a source confirmed to case managers that “The Prophet” was a real individual, but was a “joke” that had existed under other names during previous years. This source went on to say they were “disappointed” to see the manner in which “The Prophet” spoke to Witness One in the messages and that the goal of “The Prophet” role was simply to keep new members engaged and teach them about the chapter.

Four of the eight witnesses stated they had never heard of “The Prophet” before — two said they knew of the figure but only that the role was “not serious” or “a joke.”

The report noted that because the existence of “The Prophet” was corroborated by three witnesses and one additional
source, denial of “The Prophet’s” existence by the other four witnesses impacted the reliability of their accounts.

Witness One also provided a “signature sheet” — a list of new member events — including items like chugging a gallon of milk and consuming an onion in under five minutes. Witness One stated that new members of D Sig were “forced” to drink a gallon of milk before a hazing session to ensure they would vomit and had to complete the signature sheet.

A source confirmed to investigators that the signature sheet was provided to new members but was intended to be “fun” and in “good faith,” and that there was no set amount of items that new members had to complete. The source acknowledged the list included milk chugging and onion eating. Witnesses two through eight all recall the sheet, but several said it was voluntary and they were not pressured to complete a certain number of tasks.

One of the items on the sheet was to “take an item from a rival frat or sorority.” A day after the Nov. 7, 2025 interim suspension of D Sig went into effect, three new members were stopped on suspicion of theft. They admitted they were headed to Theta Chi to steal their flag — and were later caught on camera at Sigma Nu carrying a ladder.

An incident report by the university identified the three as D Sig pledges. While they had not had contact with any active members, which was not allowed per the interim suspension, taking an item was included on the signature sheet for new members.

Witness One also reported that pledges were forced to clean vomit after parties and put their faces on or near the dirty floors. The executive board member who was spoken to denied that any new members were forced to clean, but rather it was a voluntary process after an event that active members also participated in. Several other witnesses said they recall cleaning after parties but they were not forced to do so.

The investigation found that there was not sufficient evidence to support that there was ever existence of a “dungeon,” that new members were ever lined up against a wall or were forced to wear a certain outfit for hazing. These were claims made by Witness One, but no other witness confirmed these activities.

Action plan

An action plan is an assigned plan by the dean’s office which aims to help student organizations found in violation of the Student Code of Conduct “realign” with institutional values. D Sig’s action plan includes the decision to disaffiliate the fraternity as well as an immediate prohibition on chapter facility use.

D Sig’s house can no longer host chapter-related gatherings, store chapter property, display chapter identifiers like flags or signs or maintain a “live-in” structure. The report acknowledges housing arrangements may involve private lease agreements. Current residents of the house are expected to make “best efforts to transition away from residing together in a manner that functions as, or presents as, a chapter facility,” according to the report.

Residents are expected to vacate as quickly as possible by relocating at the end of the lease term, subleasing or terminating their lease early. The report indicates that, due to historical association of 1306 E 18th Ave. with D Sig, and that code violations took place at that location, individuals are expected to vacate the address by the time their lease term ends.

Ten days after the letter was sent, every resident of the former chapter house had to submit confirmation of their lease end date or plan for vacating the house to the code of conduct office.

According to UO spokesperson Angela Seydel, D Sig filed an appeal to its suspension decision on March 18. Decisions on appeals are typically issued within 30 days.

The fraternity may apply for re-recognition no earlier than spring 2030, and future consideration will require demonstrated compliance with university policies and standards. D Sig will remain listed as suspended and disaffiliated on the Fraternity and Sorority Life status webpage.

Seydel said some students involved may face individual code of conduct violations, and that “hazing, retaliation and behaviors that endanger community members or undermine accountability will not be tolerated.”

D Sig leadership did not respond in time for publication.
