One man was killed and four other people were injured in a pair of shootings early Sunday morning.
Police said they believe the two shootings, which happened near the University of Illinois Urbana-Champaign campus, may be related.
Authorities said the first shooting apparently stemmed from an argument at an apartment party on East Green Street.

"Our preliminary investigation completely points to an argument taking place at the party and the argument spilled out into the street and that's when a fight occurred," Champaign police spokeswoman LaEisha Meaderds said.
She added that it is unclear what led up to the fight.
Shots were fired and hit four people, none of which were involved in the fight.
One person, 22-year-old George Korchev, was killed in the shooting.
Meaderds said Korchev wasn't a student at the university and wasn't involved in the fight.
"The victims in the incident were not involved in the fight," Champaign police said in a statement. "Mr. Korchev was walking near the area when the shots were fired."
Pollice said three other people sustained non-critical gunshot wounds from the shooting.
Less than half an hour after the first shooting, officers received a report about another shooting a few blocks west of campus.
There, officers found another victim, who was transported to an area hospital with a non-life-threatening gunshot wound.
Authorities are searching for a suspect or suspects in the shootings and for a driver who hit someone who was running from the gunfire at the first crime scene.
It isn't clear how many people were at the apartment party because most people ran after hearing gunfire, but police are hoping to interview as many people as possible.
