Matt Ellis's favorite pair of sandals sat at the main campus of Texas State University, where friends, teachers, and the entire Greek community were gathered to mourn the loss of one of their own at a candlelight vigil Wednesday night.

Ellis died after a Greek party over the weekend, police say. The sophomore was a pledge for the Phi Kappa Psi fraternity.

Throughout the vigil, his fraternity brothers embraced each other and told fond memories they shared with Ellis.

“He made the greatest impact on our lives,” one student said.

Ellis was found dead at an apartment late Monday morning. After to a preliminary investigation, it’s believed Ellis may have died from alcohol poisoning.

So far, police have not filed charges in his death. Texas State, however, suspended all Greek activities on campus.

This is not the first time the school’s Greek system has been under fire after the death of a student. Last year, Jordin Taylor’s body was found under a party bus after an off-campus fraternity party. Taylor was dragged more than 500 feet after being hit by the bus.

Taylor was a freshman at the university and a member of the Alpha Delta Pi sorority.

Ellis’s exact cause of death has not been determined. An autopsy has been ordered, but officials say that results could take six to eight weeks
