WESTCHESTER COUNTY, N.Y. -- The engineer who was at the controls of the Metro-North train that derailed in the Bronx last year and killed four people reportedly has sleep apnea, according to The New York Times.
A report by the National Transportation Safety Board set to be released this week says William Rockefeller's sleep apnea was aggravated after a schedule change just before the crash that moved him to an early morning shift, The New York Times reported.
Rockefeller's attorney shared his medical records NTSB investigators. Sleep apnea is a condition that involves disruptions in breathing that can lead to daytime drowsiness, according to The New York Times.
The report is also expected to reveal the transcripts of Rockefeller's interview with the NTSB, The New York Times said.
