In March 1981, as an effort to demonstrate a commitment to making the complex safer, then-Chicago Mayor Jane Byrne moved into a fourth-floor apartment in the 1160 N. Sedgwick Street building with her husband. Backed by a number of police officers and a substantial personal bodyguard presence, she stayed for only three weeks, and this incident contributed to public perception of Cabrini–Green as the worst of the worst of public housing. As a security measure, the rear entryway of the unit Byrne stayed in was welded shut. This had the impact of creating a fortification for gang members when Byrne left. Many other gangs copied this technique in other units.
