The night Hussain Saeed Alnahdi was attacked started out just like any other weekend in Menomonie, Wisconsin, a college town.
Bars had just let out for the night as students wrapped up an evening of carousing. But Alnahdi, a Saudi student attending the University of Wisconsin-Stout would never make it home.
He was attacked and left bloodied in the street near Toppers Pizza, a restaurant in downtown Menomonie around 2 a.m. (3 a.m. ET) on Sunday, according to police.
Alnahdi, 24, died on Monday from injuries he sustained during the the weekend attack. No arrests have been made and investigators are treating the incident as a homicide, the Menomonie Police Department said in a statement issued Monday.
The Royal Consulate General Of Saudi Arabia in Houston told NBC New they are in touch with Alnahdi's family in his home country.
Detectives were still searching for a motive on Tuesday. Witnesses told police the assailant was a white male about six feet tall.
"The motivation of the offender is unknown at this time," Commander Todd Swartz of the Menomonie Police Department told NBC News. "It can't be confirmed at this time whether this was a hate crime."
