The mate on the tugboat involved in last week's fatal collision on the Delaware River took the Fifth Amendment and refused to meet with investigators this weekend, the National Transportation Safety Board said this morning.
On Saturday, investigators interviewed three of the tugboat's five-man crew, including the master, the engineer and one of the two deckhands. They did not interview the second deckhand, who was asleep at the time of Wednesday collision with Duck 34, a disabled tourist boat adrift in the water.
The NTSB did not say why the mate refused to meet with investigators, but noted that he "exercised his Fifth Amendment right," which protects against self-incrimination.
The NTSB also said in a statement this morning that other vessels in the area heard Duck 34 making radio calls to the tugboat, the Caribbean Sea, on Channel 13.
The tourist boat's master and deckhand told investigators on Friday that calls to the tug were not acknowledged.
