On December 2, 2024, a mass shooting at a home in the 3500 block of West 59th Street in Chicago’s Gage Park neighborhood left 32-year-old Osmer Angel Ferrer Oria dead. The attack occurred about 2:10 p.m. during a gathering; eight people in total—four men and four women, aged 20 to 35—were shot. Two other people killed were identified as 28-year-old Jon Carlos Blancarcer and 26-year-old Hector M. Sajo.

Neighbors reported screams and people fleeing the house after gunfire. The Chicago Police Department had previously responded to multiple calls at that residence, though those calls have not been described. No suspects have been identified or arrested and the motive remains unclear; detectives are interviewing witnesses and collecting evidence. A $10,000 reward is being offered for information leading to arrests, and an Emergency Assistance Center was opened to support the community.

If anyone has information about who was responsible or saw activity around West 59th Street that afternoon, please contact Cook County Crime Stoppers or the Chicago Police Department.
