The dark-colored SUV was used in a March 19 shooting in the 3100 block of West Lake Street, according to a statement from Chicago police.
About 6:50 p.m. that day, the three victims were sitting in a vehicle when someone walked up and fired shots at them, police said.
Marquel Robinson, 24, was shot and pronounced dead at the scene, authorities said. The boy was shot in the leg, while a 25-year-old woman was struck in the thigh and ankle, police said. Both were taken to Stroger Hospital in good condition.
The boy was the second child shot in Chicago in less than three hours that day. Earlier in the afternoon, a 4-year-old boy was wounded in a shooting in Washington Park.
Police asked anyone with information about the SUV to call Area Three Violent Crimes Detective Mckenna at (312) 744-8261.
