Had to look the car accident up. I mean that both are killed sounds suspicious, but in case it was by revenge it was planned very well. At least bbc wrote that the women which caused the car accident even stayed at the scene, so no hit and run. And my two cents regarding the Yacht are that even if it was a big boat, I would never underestimate the power of really, really shitty weather (Wasn’t even a waterspoute mentioned somewere?).
