On the evening of August 19, 2023, 16-year-old Jose Guzman and his 19-year-old brother Carlos Guzman were shot outside their home in unincorporated Glenview, Illinois. Officers found both brothers with multiple gunshot wounds in the 14000 block of Michael Todd Terrace shortly after 9:06 p.m.; Jose was pronounced dead at the scene and Carlos later died at a local hospital. A 16-year-old boy suffered a graze wound to the back.

Investigators say the attack was tied to a July 2023 altercation between Jose and 22-year-old Carlos Miranda of Prospect Heights. Detectives report Miranda and a 15-year-old associate confronted the Guzman brothers on August 19, with Jose shot at close range and Carlos and the other boy struck while fleeing. Multiple shell casings and a cellphone linked to the juvenile were recovered; cellphone records, surveillance and other digital evidence led police to identify 42-year-old Griselda Martinez of Itasca as a lookout and 19-year-old Sergio Patino-Jaime of Wheeling as involved in disposing of the getaway vehicle. On December 19, 2023, all four were charged with two counts of first-degree murder and one count of attempted first-degree murder.

Jose was a Glenbrook South High School student about to begin his junior year; Carlos had graduated from the same school and hoped to become a barber. A memorial was placed outside their home and a GoFundMe was started for the family.
