A 9-year-old boy was killed in a crash Monday night in south suburban Calumet City.

The two-vehicle crash happened at 6:56 p.m. at Torrence Avenue and Michigan City Road, according to Calumet City police.

A vehicle heading south on Torrence tried turning east onto Michigan City Road and was struck on the passenger side by a vehicle heading north on Torrence, police said.

Four people — two adults and two children — in the southbound vehicle, including 9-year-old Jose Antonio Martinez, were injured, police said.

Martinez, a resident of Hammond, Indiana, was taken to Christ Medical Center in Oak Lawn, where he died at 7:38 p.m., according to police and the Cook County medical examiner’s office. An autopsy Tuesday found he died of craniocervical injuries, and his death was ruled an accident.

The other three victims’ exact ages, genders and conditions weren’t immediately available.

Only the driver was in the northbound vehicle.

The Suburban Major Accident Reconstruction Team is assisting Calumet City police with the investigation.
