Who are Bill, Jake, and Turner? How does Huck try to help them?

These guys are a gang of murderers whom Huck and Jim discover on the sinking steamboat the Walter Scott. The ferryboat is sinking with the murderers still trying to get their money. Huck tgoes ashore and finds a ferry night-watchman. To try to save the robbers, because he feels guilty leaving them for dead, he tells the man that his family ran into the wreck while traveling downriver and that they are stuck there. The man immediately gets his ferry moving to try and save them. However, before he gets very far, the wreck floats by, having come loose and sunk even further. Huck realizes that all three men aboard the wreck have surely drowned.
