Helmut Jahn, a prominent German architect who designed an Illinois state government building and worked on the design of the FBI headquarters in Washington, was killed when two vehicles struck the bicycle he was riding outside Chicago.
Jahn, 81, was struck Saturday afternoon while riding north on a village street in Campton Hills, about 55 miles west of Chicago. Jahn failed to stop at a stop sign at an intersection and was struck by the two vehicles, headed in opposite directions, Campton Hills Police Chief Steven Miller said in a news release.
