The passengers who were on the Ontario-based air ambulance flight that went missing off the coast of Nantucket have been identified, as the Transportation Safety Board of Canada said it will be leading the investigation into what happened to the aircraft. 

The medevac flight that disappeared early Saturday was being operated by Hamilton, Ont.-based Latitude Air Ambulance, en route from Bermuda to Boston, carrying a patient accompanied by a family escort.

The other four people on the plane — two pilots and two medical staff — were Canadian and have not yet been identified.

On Monday, the Bermuda Police Service identified the two passengers as Bermudian nationals Marilyn Lavonne Bean, 66, and her 41-year-old son, Sergio Wayne Lottimore.

The Gulfstream G100 jet C-GRJP had the callsign Heartbeat 104, and went missing early Saturday morning off the coast of Nantucket in the Atlantic Ocean.

The U.S. Coast Guard called off the search late Sunday evening after 66 hours.

A Latitude spokesperson told the Star on Sunday evening that company staff, many of whom rushed to the office and worked overnight Saturday, are in contact with family members of the crew and are planning to release more details.

“Given the information shared by authorities and the conclusion of the search and rescue phase, we must now face the heartbreaking reality that the four members of our Latitude team, our patient and the patient’s family escort, who were aboard Heartbeat 104, are presumed to have died,” Latitude said in a press release late Sunday night.

“Our four crew members were valued members of the Latitude family. They dedicated themselves to providing care to people at some of the most difficult moments in their lives, and they were carrying out that mission when this tragedy occurred. We are grieving their loss deeply and will continue to support their families and our employees through the difficult days ahead,” said the release.

On Monday, the Transportation Safety Board of Canada put out a statement saying it is leading the investigation. 

“Pursuant to international agreements, the investigation shall be conducted by the State of registry, which is Canada. The TSB will be assisted by the (U.S.) National Transportation Safety Board as accredited representatives, and in the coming days will deploy investigators to assist in the search and recovery of the aircraft,” said the release.  

Warwick Academy, the school Lottimore attended in Bermuda, remembered him as a school prefect and an “outstanding person.”

Hamilton Re, the Bermuda insurance firm where he served as a senior vice president, said it had lost a “ respected leader, colleague and friend.”

In a statement, Bermuda Premier David Burt expressed his condolences. 

“While we held out hope for the best, the worst fears have been realized, and so our first thoughts are with the families of those so tragically lost.”

A search remains ongoing off the Massachusetts coast for an air ambulance carrying six people that disappeared during a flight from Bermuda to Boston. A “debris field” was found later Saturday off the coast of Nantucket, the Coast Guard said. (Oct. 4, 2026)

Air traffic controllers lost contact with the flight around 1:30 a.m. Saturday, about 20 minutes outside its destination of Boston’s Logan International Airport.

Very little is known about what happened in the final moments of the flight.

The plane went missing early Saturday carrying four staff and crew from the GTA and Hamilton areas, along with a patient and family escort.
