Authorities say they have been looking for the person who was behind the wheel of a white car. They think it may have forced another vehicle off the road, causing a crash that killed a Chicago man.
John Khosho, 23, died Thursday when his car struck a tree in the 3800-block of Dempster in Skokie.
Khosho was wearing a seat belt, and his air bag deployed.
So far, the man being questioned has not been charged.
