Julian Hernandez was 16 when he was shot and killed on February 19, 2017, in the 1900 block of North 17th Avenue in Melrose Park, Illinois. He was found bleeding on the street, treated by bystanders, and taken to Loyola University Medical Center in Maywood, where he was pronounced dead at 5:16 p.m. The Cook County medical examiner ruled the cause of death a gunshot wound to the torso.

Police say the shooting began after an argument in front of an apartment building involving Reinaldo Collazo Sr., 49, and his son Reinaldo Collazo Jr., 22. Collazo Sr. allegedly retrieved a firearm and fired a shot into the air, then handed the gun to his son; Collazo Jr. then fired at least one shot that struck Julian. Collazo Sr. was arrested at the scene; Collazo Jr. fled and was captured days later in Schiller Park. Collazo Jr. was charged with first-degree murder, and Collazo Sr. faced charges including reckless discharge of a firearm, possessing a firearm without a FOID card, and obstructing justice.

Julian was reported to have gang affiliation, as were the Collazos, and the case drew attention to gang activity and illegal firearms in the community. Does anyone have information about Julian’s last movements or the argument that led to the shooting?
