(RNN) - Philadelphia Mayor Michael Nutter announced Thursday morning that all people are believed to be accounted for in Tuesday's deadly Amtrak train derailment.
The fatality count was raised from seven to eight when a body was found in the wreckage Thursday morning. More than 200 additional people were injured when Train 188 traveling from New York City to Washington, DC, went off the tracks rounding a curve.
"With the recovery of and identification this morning, we believe that we have now accounted for all 243 individuals that we believe were on Amtrak train number 188 from Tuesday night," Nutter said.
Philadelphia Fire Commissioner Derrick Sayer said around 8 a.m. Thursday, a cadaver dog was called out to do a search of one of the train cars that had a large amount of wreckage. The dog hit on a couple of spots, and authorities were able to find one other passenger in the wreckage. The body was extricated and transported to the medical examiner's office.
The lawyer for the engineer said his client, Brandon Bostian, does not remember the accident. Bostian has turned over his cell phone to investigators, and has given a blood sample. Bostian, who was also injured in the accident, claimed he was not drinking or doing drugs.
There are still 43 people hospitalized, 18 of whom are at Temple University.
The train's black box was recovered, and a National Transportation Safety Board investigation revealed it was traveling at 106 miles per hour before the engineer tried to apply the brakes. The speed limit on the curve is 50 miles per hour.
According to CNN, video shows the train speeding up before the derailment. The train reportedly sped up from 70 mph to 100 mph before the crash. The cause of that acceleration is unknown.
Amtrak said it plans to resume limited service between Philadelphia and New York on Monday.
In a statement by CEO Joe Boardman, the company said "With truly heavy hearts, we mourn those who died. Their loss leaves holes in the lives of their families and communities. On behalf of the entire Amtrak family, I offer our sincere sympathies and prayers for them and their loved ones. Amtrak takes full responsibility and deeply apologizes for our role in this tragic event."
The last time the train line had a derailment in the Northeast Corridor was 28 years ago.
"Twenty-eight years and 300 million people have ridden Amtrak since then," Boardman said. "No derailment, no loss of life."
