Jonathan Ceballos, a 22-year-old Hispanic man, was killed on October 31, 2021, in Joliet, Illinois. He was at a large Halloween party on East Jackson Street when gunmen opened fire about 12:39 a.m.; shots were fired from an elevated position and struck people in the crowd. Jonathan and another attendee, Holly Mathews, were pronounced dead at the scene. The intended target, Sergio Hernandez, was paralyzed in the attack and later died of his injuries a year afterward.

Authorities arrested several suspects in connection with the shooting. David Grijalva, 23, was taken into custody at his workplace and charged with multiple counts including first-degree murder. Joskar S. Ramos, 18, and brothers Thomas Lopez, 21, and Jeremy Lopez, 19, were also charged with first-degree murder, attempted first-degree murder, and weapons offenses; those three were identified as members of the Vice Lords street gang. Defense attorneys have contested the sufficiency of evidence in at least one case and the defendants remain held on substantial bonds.

Jonathan is remembered by family and friends as kind and caring. Does anyone have information about that Halloween night on East Jackson Street or remember details that could help investigators or the families?
