CHICAGO (AP) — A cockroach embarrassed a Chicago official in charge of pest control when it took a stroll near him in full view of some aldermen, and its stunt just might have cost it and its buddies their lives. After Thursday's hearing in the City Council chambers, Fleet and Facilities Management Commissioner David Reynolds had his office call a private contractor to come down to City Hall and do some exterminating. The cockroach couldn't have picked a worse time to show its antenna on the wall of the City Council chambers: just as Reynolds was testifying during a budget hearing.
