Darius Pinex, 28, of the 6400 block of South Lowe Avenue, was dead on the scene, according to the Cook County Medical Examiner’s office.

The chain of events began when police saw a car which matched a description of one used earlier in an incident where shots were fired. Officers pulled the car over and ordered everyone inside to get out.

At that point, the passenger opened his door while the driver put the car and reverse, police said. The car struck and began to drag one of the officers, then struck a light pole, police said.

The car then began to move forward as the driver tried to strike the other officer, who opened fire on the driver. The passenger is in police custody, police said.

The officer who was hit by the car suffered minor injuries, police said.

Wentworth Area detectives and the Independent Police Review Authority, which investigates all police-involved shootings, are investigating.

Three people were shot and wounded by police in two separate incidents earlier this week. The suspects have all since been charged.

Two 15-year-old boys were shot by police Tuesday night in the 4300 block of West Roosevelt Road. They allegedly put their car in reverse and struck a squad car, then accelerated forward and struck an officer.

Both teens were charged as juveniles with several criminal counts and traffic citations.

Also Tuesday night, police shot and wounded a man in the 4200 block of South Calumet Avenue, after the man allegedly pointed a weapon at an officer as they tried to conduct a field interview with him.

The man, Donte Gross, 23, was charged with felony unlawful use of a weapon, felony aggravated assault to a police officer and misdemeanor possession of a firearm without a FOID card.
