He commits suicide after killing Gatsby.
While in the swimming pool he is killed by George Wilson.
Gatsby died towards the end of the novel. Wilson shot him and then killed himself at Gatsby's home. He blamed Gatsby for hitting Myrtle with his car and killing her; when in reality it was Daisy driving.
Gatsby--after taking the blame for Daisy accidentally hitting Myrtle in his car--is killed by Myrtle's husband, George. George is led to Gatsby after a vengeful Tom tells him that Gatsby is the man who killed Myrtle. As a result, George finds him, kills him, and then takes his own life. More info and analysis from the link included.
All of the characters contribute to Gatsby's death, escpecially Daisy because he loved her and she didn't want to leave Tom for him. The fact that Tom is having an affair with Myrtle contributes to Gatsby's death because if it weren't for the affair, Gatsby would have never been involved with Myrtle's death. Everyone's greedy grabs for the "American Dream" was the cause of Gatsby's death. ----------------------------------------------------------------------------- More precisely, when Gatsby and Daisy were driving together in Tom's car, Myrtle came out and waved at them. Daisy decided not to swerve the car away and ended up killing Myrtle (most likely because Myrtle was Tom's mistress). Tom told Wilson, Myrtle's husband, that Gatsby was driving the car, so Wilson decided to go and take revenge by killing Gatsby. Thus, Tom's affair with Myrtle triggered Daisy's hatred for Myrtle which triggered Myrtle's death which triggered Gatsby's own death by the hand of Wilson.
