Yankees pitcher Cory Lidle was the sole person aboard the plane that crashed Wednesday into a high-rise apartment building in New York, FBI officials told CNN.
Emergency responders found his passport in the street below, the officials said.
The small airplane was a Cirrus SR-20 registered to Lidle, 34, said Yankees manager Joe Torre.
There was a mayday, FAA reports, from the pilot involving a problem with fuel before the aircraft crashed into the 50-story high-rise on Manhattan's East Side.
One other person was reportedly killed, according to the New York City Fire Department and New York City Police Department.
