Grand Jury to Investigate Philly Building Collapse

Six died

The city's top prosecutor announced Monday he would convene an investigating grand jury to look into a building collapse that killed six people and injured 13 others last week.

District Attorney Seth Williams said the "scope and depth" of the grand jury process will help prosecutors, the city and others to "completely and appropriately investigate" the accident, which happened as a downtown building was being demolished and collapsed onto a neighboring Salvation Army Thrift Store on Wednesday, killing two employees and four customers.

The grand jury will hear from witnesses, gather information and other documents as it looks into everything that preceded and allowed for the collapse, Williams said.
