On Thursday, crews spent the day looking for those who had been reported missing among the rubble.

"We removed some debris and then we searched under it, moved some debris and that’s how we found the victims we were looking for" said Special Operations Chief Craig Murphy, with the Philadelphia Fire Department.

"The search and rescue part is complete. right now we are clearing the area for the next part of the investigation" said Fire Commissioner Lloyd Ayers in a news conference on Thursday.

“We have a lot of work to do to figure out why what happened yesterday happened, how did it happen and certainly going forward, how we can best prevent any incident like this happening anywhere in the city” said city Mayor Michael Nutter.
