A man and woman were killed in a crash Monday afternoon on the Bishop Ford Freeway in south suburban South Holland.

Edward Robinson, 58, was driving a gray 2004 Pontiac sedan in the middle lane of northbound I-94 south of 159th Street in South Holland when he slowed down to make a lane change to the right, according to Illinois State Police. A black 2007 GMC SUV then crashed into the back of the Pontiac when it slowed down.

Momentum from that impact caused the Pontiac to slam into the far right concrete wall before bursting into flames, state police said. Edward Robinson and his two passengers were trapped inside.

Edward Robinson, who lived in Chicago, was taken to St. Margaret Hospital in Hammond, Indiana, where he died, state police said. Charlene Robinson, 93, who was sitting in the back seat, was dead at the scene.

An autopsy Tuesday found she died of multiple injuries from the crash and her death was ruled an accident, the Cook County Medical Examiner’s Office said. It was not immediately clear where she lived.

The front-seat passenger, a 46-year-old woman from Houston, Texas, was taken in serious condition to Christ Medical Center in Oak Lawn, police said.

The 31-year-old woman driving the GMC and her two passengers, a 30-year-old man and a 3-year-old girl, were not injured, according to state police. All three of them live in Hobart, Indiana.

All lanes of the Bishop Ford south of 159th were closed for investigation until 3:15 p.m., state police said. It was not immediately known whether drugs or alcohol were factors in the crash.
