The Coast Guard suspended the search at Thursday for four people 15 miles east of Eleuthera, Bahamas.
According to a Coast Guard news release, Miami air traffic controllers lost radar and radio contact with the twin-engine MU-2B plane at 2:10 p.m. Monday, about 37 miles east of Eleuthera, Bahamas.
The people on board the plane were identified as Nathan Ulrich of New Hampshire and Jennifer Blumin of New York, along with her 3-year-old and 4-year-old sons.
Blumin, 40, was founder and CEO of Skylight Group, which provides event space around New York City, specializing in the fashion industry.
"This was a swift and significant loss and its impact has reverberated through everyone that participated in the search," said Christopher Eddy, search and rescue mission coordinator. "Our hearts and prayers go out to all of the families involved."
Crew searched for more than 75 hours for the four people, and covered more than 11,140 square miles, an area larger than the state of Massachusetts.
The U.S. Air Force, Customs and Border Patrol and the Royal Bahamas Defense Force also assisted with the search.
The airplane departed Borinquen, Puerto Rico, at approximately 11 a.m. Monday en route to Titusville.
On Tuesday, a Coast Guard Air Station Clearwater MH-60 Jayhawk helicopter crew located a fuel sheen and a debris field 15 miles east of Eleuthera, Bahamas.
The helicopter crew was able to lower a rescue swimmer and retrieve some of the debris to transfer ashore for identification, the Coast Guard said in a release. Some airplane components recovered from the debris were confirmed to be from an MU-2B airplane.
A National Transportation Safety Board accident investigator has been assigned to this case to determine the probable cause of this accident.
