Answer the following question: Question: Why does One of the goons kills the third? If there is no answer, please output "Insufficient information to provide an answer.".

One of the goons kills the third in order to keep the money between himself and his partner, Jerry. John manages to escape from the goons and after helping Kelly and Emery escape, shoots the fuel tank on his boat, killing one of the goons. The other one, Ice, (Coolio) is killed by the shark attempting to retrieve the money. John manages to lure the shark under the oil rig and Emery activates the drill and drops it into the shark's mouth, finally killing it. John, Kelly and Emery have a tooth from the shark as proof of their kill (the shark bit John in the foot and a tooth broke off that he retrieved) and debate whether to collect the reward, but Emery, still believing the shark is a spirit in physical form, suggests that now that it is dead, that they...
