PHILADELPHIA (CBS/AP) — The Italian government has confirmed that one of its citizens, businessman Giuseppe Piras, also died in the Amtrak crash.

Piras is the last of the eight victims to be identified in the Philadelphia wreck that also injured more than 200.

Italian officials say he was in the United States for work. Italian media report that Piras was from Sardinia and worked in the wine and olive oil business.

The others killed are a Maryland businessman; an Associated Press software engineer; a New York City commercial real estate professional; a midshipman at the U.S. Naval Academy; a Wells Fargo executive; a college administrator; and the CEO of an educational startup.

Officials say now a criminal investigation into why the train was going twice the legal speed limit is underway.

NTSB member Robert Sumwalt asks, “What was going on in the cab of that locomotive that may have led to this situation?”

The attorney for the train’s engineer was not available for comment.
