BOSTON (AP) — Investigators trying to learn why a commercial fishing boat sank off Massachusetts nearly a year ago, taking the lives of all four crew members, are using some high-tech gadgetry in their probe, federal authorities said Wednesday.

The 82-foot (25-meter) Portland, Maine-based Emmy Rose went down early Nov. 23 as it was heading to port after a seven-day fishing trip, the National Transportation Safety Board said in a statement. Authorities have previously said it was heading to Gloucester, Massachusetts.
