The 56-foot sea scalloping vessel that sank with four aboard on Nov. 24 has been located according to the Massachusetts Environmental Police.

Maj. Patrick Moran confirmed that the F/V Leonardo was located on Sunday, sitting upright in 140 feet of water.

The vessel was located based on the distress signal activated when it began to sink, Major Moran said. Once the vessel was located, police deployed a remote operated vehicle, equipped with lights and a camera, to visually identify the vessel, he also said.

The Leonardo sank in rough seas the week before Thanksgiving, 24 miles southwest of Martha’s Vineyard. Of the four fishermen aboard, only one, Ernesto Garcia, was rescued by the Coast Guard.

The other three fishermen — Gerald Bretal, Xavier Vega, and Mark Cormier Jr — are presumed lost at sea.

On Sunday morning the Coast Guard dispatched the 52-foot search vessel Thomas Paine, with three members of the New Bedford police department on board, according to Major Moran. They were aided by a state police vessel with members of the underwater recovery team also on board. The vessel was located at 10 a.m., using side scan sonar technology.

Major Moran said the windows of the sunken vessel were not broken and there was no noticeable damage to the hull.

“A tragedy like this affects us all. We deal with these people every day and we wanted to give it an effort to get out there and locate them,” Major Moran said.

An investigation by the U.S. Coast Guard into the incident remains ongoing.
