A city employee caught in gang crossfire was among five people killed and 40 more wounded in shootings across Chicago between Friday afternoon and Monday morning.

Chicago Police issued a statement Sunday in the middle of one of the first consistently warm weekends of the spring, as intensified city gun violence typically accompanies rising temperatures.

“As we look toward the summer months, Superintendent Johnson has made it very clear that the violence will not be tolerated – period,” the statement said. “The cause of the violence traces back decades, and everyone has a role to play in fixing it – police working with parents, judges, residents, clergy, community leaders, and others. Put simply, we need more values, fewer guns and stronger sentences against violence offenders.”
The first attack of the weekend happened about 4 p.m. Friday in the Bronzeville neighborhood, where Yvonne Nelson, an operator for the city’s 311 service, was walking out of a Starbucks near 35th Street and State when shots rang out, authorities said.
A 19-year-old man flagged down officers on the block saying he had been shot, and they found the 49-year-old Nelson on a sidewalk nearby with a gunshot wound to the chest, according to police and the Cook County medical examiner’s office.
Nelson, of the 4900 block of South Vincennes, was taken to Stroger Hospital, where she died at 4:33 p.m., authorities said. She had worked for the city since 2002, according to the city’s Office of Emergency Management and Communications.
The man — who police said was a documented gang member and the intended target of the shooting — was taken to Northwestern Memorial Hospital with gunshot wounds to the hand and buttocks. His condition stabilized, police said.
The shooting happened just minutes after a press conference touting a sweep of arrests in a gang investigation at Chicago Police headquarters, which is two blocks east of the crime scene.
