A coalition of authorities is deploying technology to try to locate the wreck of a fishing boat that sank last month off Massachusetts, killing all seven aboard. Winter weather and sea conditions have thus far slowed their efforts. The 72-foot vessel Lily Jean was returning to port early Jan. 30 to repair fishing gear when it sank in frigid Atlantic waters off the historic fishing port of Gloucester. Officials say Wednesday that multiple agencies, including the U.S. Coast Guard, National Oceanic and Atmospheric Administration and Massachusetts Environmental Police, are cooperating to try to find the wreck of the ship and potentially recover the bodies of the deceased.
