Seth Williams Convenes Grand Jury to Investigate Building Collapse

District Attorney Seth Williams announced today that a grand jury is being convened to investigate the Market Street building collapse that killed six and injured 13 last Wednesday. He said excavator operator Sean Benschop was charged with involuntary manslaughter because toxicology reports found the presence of drugs in his system, and that the purpose of the grand jury was to find out–without “rushing to judgment”–whether any others should be held criminally responsible. Federal officials will not be involved, he added.
