A suburban man was killed and another injured this morning when the car they were in crashed on Interstate 88 near Oak Brook, authorities said.

A spokeswoman for the DuPage County coroner’s office said the 29-year-old man’s name was not being released as of this afternoon, pending notification of his family.

A 2006 Ford Mustang was heading west on I-88 just east of the Oakbrook Center shopping mall when its driver lost control, struck a guardrail and went into a ditch, said Illinois State Police Tollway District Master Sgt. Tim Moore. The car then flipped and one man was ejected.

Both men, age 29 and of the suburbs, were taken to Advocate Good Samaritan Hospital, where one man was pronounced dead and another’s condition was not life threatening, according to Moore.

The wreck happened at 4:55 a.m., said Moore, who did not know what caused the crash or if weather factors had contributed.

Traffic was tied up until about 8 a.m. and the Mustang had to be towed from the scene.

No citations had been written as of early this afternoon as police are still trying to determine which man was driving.
