I can only think of one person who has died near TSI. There was a group of college kids there and they had had a few too many drinks so they stayed behind on the island after dark. Well, after the effects the alchohol wore off, they decided it was getting boring on the island, so they decided to swim back to the mainland. One of the guys kid brothers didn't know how to swim and he drowned. As for the TTA, that is the leading cause of deaths in the park. Because there are no restraints and all of those dark tunnels, and if someone climbs out, they will get hit by a car. MANY people have died on the TTA. Luckily Disney has now installed pressure sensitive mats along the track. And that guy who got out during the seancé scene, he didn't actualy die. He was just severly injured. There are nets lining the drop off and he landed in one.
