On June 5, 2013, a building undergoing demolition collapsed onto the neighbouring Salvation Army Thrift Store at the southeast corner of 22nd and Market Streets in Center City, Philadelphia, Pennsylvania, trapping a number of people under the rubble. The store was open and full of shoppers and staff. Six people died and fourteen others were injured. The construction contractor, Griffin Campbell, and excavator operator, Sean Benschop, were charged with involuntary manslaughter and other charges. They were found guilty of manslaughter, and Campbell and Benschop received prison sentences of 15 years to 30 years, and 7.5 years to 15 years, respectively.
