given there ages, I would say one or two fell in or was swimming , and the other 1 or 2 fell in trying to help recover the other. Laptop on and table was set because they went outside without storing these items because it was an emergency , and they started the engine to aid the recovery........anyway the 3 guys ended up in the soup, and the boat sailer off on its own , probably a few 100 yards out of reach until exhaustion set in and they Died one by one , as they tried to swim after it. Very Sad .....
I don't think it was pirates , as they operate in the commercial world , and wouldn't leave behind valuable things ...... hostages are hard to keep and maintain, and everyone is going to be looking for them, and they might not be worth the 100k you want for them. it would be easer to kill the men, strip the boat and sink it, especially if its in a remote part of the world as it could be up to 2 weeks before they send a search party , and even then they could be in the wrong place, and you would be long gone , with no witnesses , and no evidence pointing at you , except the goods to be sold in some black market in some doggy country.......
hhmmm, Have I missed my true calling in Life ?????? maybe i could get a part in pirates of the Caribbean ???
NOT THE SHARPEST KNIFE IN THE DRAWER
