Figure this out, you are a genius

She probably had a heart attack.

thanks but i think the answer has to encorporate how she ended up on the island aswell, theres no boat or bridge or anything so i have no idea...

She obviously arrived with whoever found her dead!

thats a really good answer but its still not right im afraid

Is the question "a woman is found dead" or "a female is found dead"? Think hard. It makes a big difference.

How about she was born there,
lived out her life and died of old age ?

No but excellent answer, you guys are getting close i can tell, thanks for your help!

I think she arrived on a ship that got stranded on the island, where her companions managed to repair the ship within a few days. But now there was a problem: the delay had depleted the food on the ship, leaving too little for the whole team to survive the trip home. One team member would have to stay behind on the island and starve to save the others. So the team drew straws -- and the woman lost.

Edit: Oh damn! "She didn't starve to death".

Oh, oh, I know. She was the love child of Gilligan and an ape after the crew got rescued.

Oh listen to Defoe here. She was no Friday, Thomas!

i think i figured it out!
Erm... tell me if you guys agree...
Its a traffic island! and she was hit by a car and landed in the island with internal injuries, not visible internal injuries....
hmmm.... im not sure lol sounds far fetched...

That would be an excellent guess, moose, except that you said no scars or injuries.

She walked across to the island when it was low tide and died of asthma.

Alternately, she's Gilligan's and Mary Ann's love child.
