The crew of a duck tour boat that sank in a collision in the Delaware River last week made radio calls to a vessel involved in the crash, but those calls went unanswered, federal investigators said Monday.
The tour boat crew told investigators they made radio calls to the vessel Caribbean Sea that were not answered, the National Transportation Safety Board said.
The Caribbean Sea was towing a barge that collided with the tour boat, causing it to sink in 55 feet of water, the report said. Two people died.
In another report, the mate of the tug has refused to meet with investigators and invoked his Fifth Amendment rights.
