The United States Medical Center for Federal Prisoners, one of six federal institutions designed to handle federal inmates' medical concerns, is located at the corner of W. Sunshine Street and Kansas Expressway. Several high-profile criminals, including several mob bosses have been housed at the center. Among them, Joseph Bonanno of the Bonanno crime family and John Gotti of the Gambino crime family, who died in the center. The center also housed mass murderer Jared Lee Loughner, who perpetrated the 2011 Tucson shooting injuring US Representative Gabby Giffords.
