Matt Parkman and Audrey Hanson investigate the murder of a man and his wife, as well as the abduction of their daughter. The man (James Walker) was sitting down to a meal, and appears to have been frozen solid, mid-bite. Further, the top of his head has been sawed off, and his brain is missing. The authorities note that this fits Sylar's pattern of killing.
James's name is on Gabriel's list.
James had the ability to freeze objects, which allowed him to reduce the temperature of matter causing an object to freeze in the process. Sylar found James's name on Chandra's list, then added it to his own list. He went to the Walkers' home, killing James, stealing his ability, then freezing him with his own ability as a means of "practicing".

- In Saving Charlie, Hiro accidentally transports to a morgue where James Walker is held. He later meets James at a zoo in the past.
- In a question and answer session, writers Joe Pokaski and Aron Coleite confirmed that James Walker had the ability to freeze things before he died, but that Sylar stole it from him after he killed him. "Killed. Absorbed. Tested. In that order."
