The shooting happened in the 2500-block of Spaulding Avenue around 10:08 p.m. in the Little Village neighborhood.
The prayer vigil was being held in the front yard of a residence on Saturday night for a man who had recently passed away. It was during the vigil when someone exited a Jeep and opened fire, police said.
All seven of those shot drove themselves to Mt. Sinai Hospital. It is there where police said one of them, a 32-year-old man, later died.
He was later identified as 32-year-old Froylan Garcia of Berwyn, Illinois, according to the Cook County Medical Examiner.
All other victims were men aged 31, 51, 35, 39 and 48-years-old, and one victim is in his 30s. All were listed in fair condition, according to Chicago police. It is not clear whether any of them still remain hospitalized.
The office of 25th Ward Alderman Byron Sigcho-Lopez put out a statement Sunday, encouraging anyone with information to reach out to police, adding that, "this is a community concern and the 25th Ward office will continue to keep in touch with the block and residents of the 2500 S. Spaulding Ave. Block."
ABC7 reached out to Garcia's family Sunday morning in Berwyn, but they were too distraught to speak.
No one is in custody as police continue to investigate.
