The fire then quickly spread, leaving 33 passengers and a crew member trapped below deck.
Ginger Colbrun, an ATF spokeswoman, told the L.A. Times the bureau would not comment on the report, which has not been publicly disclosed due to ongoing criminal and civil court proceedings.
Capt. Jerry Boylan has been charged with 34 counts of manslaughter and is scheduled to be tried in federal court next month. He denies any wrongdoing.
