Jack Neylon, whose real name is , is a member of Mello's gang. He is the holder of Sidoh's Death Note after it is given to the gang by the Kira investigation team. Before Mello joined, he was involved in drug trafficking and illegal weapons sales; neither charge stuck due to lack of evidence, despite four separate arrests. After Sidoh tracks down his Death Note, Jack was forced by Mello and Ross to perform the eye trade with the Shinigami (in the manga only). Light uses the Death Note to have him mail the address of Mello's hideout. According to "How to Read 13", Jack dislikes Mello. In the anime, the eye trade and first raid attempt were cut.
