Chicago police say that a 3-year-old boy was shot and killed on Friday night on the city's Southwest side.

Police said that the incident happened at about 8:38 p.m. on Friday when a woman was heading northbound in the 4400 block of West Marquette while in a 2012 white SUV when shots were fired from a red sedan, according to FOX 32.

According to the Chicago Police Department, the child's mother got into a road rage incident earlier and left the scene, but the suspect followed her car and eventually fired shots.

The 3-year-old boy was taken to a local hospital after being shot but later died.
