A grand jury in Coconino County has indicted a former Northern Arizona University student in connection with the death of a fraternity pledge in January.
Carter Eslick faces one count of felony hazing in the death of 18-year-old Colin Martinez. The charge is a Class 4 felony under Arizona law involving the “consumption of a substance causing harm,” according to the Coconino County Attorney’s Office.
Eslick served as pledge master for the Delta Tau Delta fraternity. The NAU chapter was disbanded after the Jan. 30, 2026, incident.
The Coconino County Medical Examiner's Office determined Martinez died from alcohol poisoning. His blood-alcohol level was 0.425% — more than five times the state’s legal driving limit. Authorities say he consumed an excessive amount of alcohol as part of the rush event.
Three Delta Tau Delta leaders were arrested on suspicion of hazing shortly after. They were released from custody following an initial appearance before a judge.
Flagstaff police continued their investigation, conducting additional interviews and gathering evidence. They later submitted the case to the attorney’s office to determine whether to file criminal charges.
“The loss of a young person is always a tragedy,” says County Attorney Ammon Barker. “Our hearts are with Colin Martinez’s family, and we will diligently pursue this case toward a just resolution.”
The indictment against Eslick alleges he “intentionally, knowingly, or recklessly caused or coerced Colin Martinez to consume substances posing a substantial risk of death, resulting in his death.”
Officials say the case will proceed through arraignment and subsequent court proceedings.
The two other leaders of the fraternity also arrested have not been charged in Martinez’s death.
NAU officials confirmed Friday that Eslick is no longer enrolled in the university. They also said they have commissioned an independent investigator to "examine the events surrounding this case and make recommendations to the university."
"The passing of the NAU student is a loss that has shaken our entire community. We extend our deepest condolences to his family, friends and all who loved him," said NAU in a statement. "We are committed to learning everything we can from this heartbreaking loss and to ensuring our community is protected by the strongest possible standards of education, prevention and accountability."
