Crews pulled an eighth body Thursday from the wreckage of the Amtrak train that crashed in Philadelphia, and authorities said they believed everyone on board had been accounted for.
Derrick Sawyer, the Philadelphia fire commissioner, confirmed the eighth death. He said that a search dog discovered it in the train's mangled first car. Authorities did not immediately identify the victim.
Mayor Michael Nutter said for the first time that all 243 people on board had been accounted for.
"Unfortunately, again, we must now report that we have confirmed eight deceased from this horrible tragedy," the mayor said.
Amtrak's CEO, Joseph H. Boardman, told reporters: "Amtrak's heartbroken for what happened here."
Shortly after the announcement, the company Ecolab confirmed that Bob Gildersleeve, one of its sales executives, had died in the crash. His family had distributed his photo in Philadelphia on Wednesday, hoping that he might be found alive.
The train, Amtrak Regional 188, derailed Tuesday night on its way from Washington to New York. Federal investigators have said it was hurtling at 106 mph, more than twice the speed limit for the sharp curve where it derailed.
