Yep, looks like it was a car accident with her ejected to the roadside and the car and him over the embankment and into the ocean with his body then floating out and being recovered a few days later from the water given its advanced state of decomp. She died in hospital but was found same day they left to travel to airport.
Still unable to recover the vehicle due to rough seas in the area, but fisherman report it as being there. They'd have known where to look for it now given that she has now been identified and they know where on the road she was found gravely injured.
I suspect that all the media attention that this is just receiving has caused the hospital to report their unidentified … and allowed them to link it to the unidentified male found in the water days ago.
The article below also has them consuming a bottle of rum with their Canadian friends the evening of their departure and that they parted ways approx. 10pm. Friend says they were worried about the 2 and a half hour drive to the airport. Leaving at 10pm would put them into the airport at 1230 am, provided they had already packed up and checked out (we know they hadn't checked out by this time). So, after they parted company with the Canuks, they still had to clear out of their room and check out of the hotel. Google directions has that as a 2 hour, 20 minute trip in optimal driving conditions. Flight was at 2am. Car seen at 0141hrs going through toll booth(s).
IMO, Occam's razor is applicable: Bottle of rum, driving at night on unfamiliar roads. 2 hour and 20 minutes on google maps. Unfamiliar and at night. Possibly with alcohol in the system. IMO, they may have gotten lost and were now rushing the driving due to the time, and possible alcohol as a factor in addition to unfamiliarity and night driving. Autopsies are pending, but I'm just not seeing any foul play in this one.
Missing New York couple’s rental car was seen at a toll booth after they missed their flight from the Dominican Republic
Such a tragic end to a vacation.
Edit to add: Canuk friend says their flight was at 0200hrs, so unlike the article - they had not actually missed it yet when they made that last toll booth sighting. Another reason why I think they got lost and were speeding the car up trying to make that flight.
