2 killed in rollover crash on I-57 in Peotone

Two people died after being thrown from a car in a rollover crash Thursday on Interstate 57 in southwest suburban Peotone.

A Chevrolet Impala was headed south on I-57 north of Peotone Road at 11:58 p.m. when it hit a semitrailer and rolled over into the expressway’s northbound lanes, according to Illinois State Police.

The driver of the Impala, identified as 30-year-old Jerry McCullum of Bradley, and his passenger, 20-year-old Bryanna Dean of Kankakee, were thrown from the vehicle during the crash, state police said.

Dean was taken to St. James Hospital in Olympia Fields and pronounced dead at 12:52 p.m., according to the Cook County Medical Examiner’s Office.

McCullum was airlifted to Loyola University Medical Center in Maywood, where he died at 1:25 a.m. Friday, authorities said.

Autopsies found they both died of injuries from the crash, and their deaths were ruled accidents, the medical examiner’s office said.

The driver of the semi was not injured, police said.

An investigation into the crash was ongoing.
