ROCKFORD — One man is dead and another is injured in a shooting Sunday in the 1400 block of West Jefferson Street.

The violence broke out about 5:45 p.m. when individuals arrived at a Jefferson Street house party and a confrontation broke out, said police Chief Dan O’Shea.

"There were multiple subjects firing weapons," he said.

A 24-year-old man was pronounced dead at a Rockford hospital. The other victim, also a man, suffered injuries that were not life-threatening, police said.

No arrests have been made.

"So right now it’s a murder investigation, and we don’t have much more than that," O’Shea said. "The detectives are interviewing all the witnesses."

This marks the fourth homicide this year in the city.
