A fight between two fraternity brothers at an Indiana university has left one dead and the other facing aggravated assault charges.

Witnesses reported that Brady DiStefano, 19, was seen choking Caleb Zweig, 20, on a sidewalk after an altercation on Friday night. 

The students were friends and brothers at the Indiana University of Pennsylvania Phi Delta Theta fraternity.

Police say they are working under the assumption that the two had been drinking, according to WCVB.

Zweig was found unresponsive on the 800 block of Wayne Avenue around 11:30pm on Friday. One witness called police after pulling DiStefano off of Zweig, choking him. He was taken to the hospital and later died of his injuries.

Police went to DiStefano's home on South 7th street at 8:30am on Saturday to inform him that his friend was dead, which caused him to become 'visibly distraught'.  

DiStefano and Zweig, of Rockville, Maryland, had both recently been inducted to the fraternity in December.

The charges against DiStefano may change as more details emerge about his death, as the preliminary autopsy was inconclusive.

District Attorney Patrick Dougherty said: 'Unfortunately, without knowing the cause of death, we're not comfortable to charge anything more at this time, but hopefully, in the coming weeks, we'll know more in regard to the cause and manner of death.'

The loss has shocked the school's community. 

'Our hearts are broken when something like this happens,' said IUP Executive Director of Communications Michelle Fryling. 

'It is just tragic and horrible for all involved. And we are continuing to provide support to the family and to all the Greek community that was involved and the entire university community.'

Zweig aided two soldiers in the rescue of a young woman whose car flipped over after texting while driving in 2015.

He called the incident 'one of the most heroic actions of my entire life,' and helped pry open the car door to pull the woman out of the wreckage.
