According to ABC News, Brandon Bostian—the engineer driving the Amtrak train that derailed Tuesday night, killing at least seven people—says he has “no explanation” for the crash because he can’t remember it.

Bostian’s attorney is never named in the article, but he apparently contacted the network and “confirmed his identity” in some way.

Brandon Bostian, the engineer driving the Amtrak train that derailed in Philadelphia Tuesday night, has no recollection of the crash itself and “no explanation” for what happened, his attorney told ABC News.

Bostian was “very distraught” to learn of the loss of life in the crash, the attorney said, adding Bostian only remembers driving the train to the crash area generally, then later getting tossed around, coming to, finding his bag and his cell phone, and dialing 911.

Bostian suffered a concussion and head wound that required 14 staples, as well as injuries to both of his legs in the crash, the attorney said — but Bostian told the attorney he had “no health issues to speak of” before the crash and was on no medications.

Even so, some details are becoming clear. The NTSB says the train was traveling at more than 100 mph in a 50 mph zone and investigators believe Bostian pulled the emergency brake “just moments” before the crash.

Bostian has reportedly been employed at Amtrak for nine years as both a conductor and an engineer.
