This happened in East Chicago, Indiana, not Chicago, Illinois.
I did some exhausting research (exhausting on this dinosaur computer of 64 mb ram and 333 MHz processor on a dial up connection)... here's the story I was able to find in 10 minutes with the most info.

CROWN POINT | Police are holding George Soltis, 58, of Whiting, on probable cause attempted murder charges after Lake County police took him into custody Wednesday evening after he and his wife were involved in a domestic dispute on Cline Avenue.
Soltis had a gun and a bomb in his vehicle, and police called on the Porter County Bomb Squad to locate and detonate explosives in the back seat of the car. The bomb was successfully detonated, and there were no injuries reported during the process, although southbound Cline Avenue, north of Columbus Drive in East Chicago, was closed for several hours during the process.
Police believe Soltis intended to take his 42-year-old wife somewhere and kill her, said Lake County Sheriff's police spokesman Mike Higgins. His wife, who had a restraining order against Soltis, was taken to St. Catherine Hospital in East Chicago, where she was treated and released.
