CHICAGO (WLS) -- An off-duty Chicago police officer was critically injured in a crash on the Eisenhower Expressway Sunday night, police said.
Chicago police confirmed Monday morning that the man injured in the crash is an off-duty CPD officer and is in very critical condition at Stroger Hospital.
The single-car crash occurred at 11:57 p.m. on the inbound Eisenhower near the Kedzie exit, Illinois State Police said.
Illinois State Police troopers spent hours reconstructing the accident. The car apparently went up an embankment, then came down and across three lanes of the expressway before slamming into a concrete barrier.
Chicago police said the officer is 32 years old and has been on the job for two years.
Overnight, several patrol cars arrived and parked in front of the emergency room as many officers came to offer support as this officer fights for his life.
Illinois State Police are trying to determine what caused the driver to lose control.
Traffic on the Eisenhower was blocked for the investigation before reopening at about 3:30 a.m. Meanwhile Blue Line service, which runs between the Eisenhower's inbound and outbound lanes, was stopped, according to a CTA alert. All trains were only operating from the O'Hare to the UIC Halsted stop. Service was later restored.
