- Michael: "I thought you were the corrupt division."
- Dave: "Corrupt? Only a little. Definitely below average."
- ― Michael and Dave during "The Wrap Up".
At some point prior to 2004, Dave Norton began working in the FIB. Norton discovered the whereabouts of well-known bank thief Michael Townley and made a deal with him: to give Trevor Phillips up to the FIB and fake his death in the process, in exchange for letting Townley "kill" him in the upcoming bank heist in Ludendorff, North Yankton, which would advance Norton's career, since he would be killing one of the most wanted men in America.
Grand Theft Auto V
In 2004, during the events of "Prologue," Dave ambushes the heist team as they make their escape. Using a sniper rifle, he attempts to shoot Trevor Philips, but accidentally shoots Brad Snider instead, and feigns a shot at Michael. Trevor manages to escape and Brad later dies, and Norton allows Michael to provide information to the Bureau in exchange for a new identity, a pension and a relocation to Los Santos. To aid this, Brad is buried in Michael's grave.
Some time later, Dave intercepts a letter to Brad (who is believed by the public to be incarcerated). The letter has no name but it came from Sandy Shores, and Norton deduces that it was written by Trevor. Assuming Brad's identity, Norton begins corresponding with Trevor, using this as a way to keep track of him.
For the next nine years Michael lives in Los Santos under the surname De Santa, with Dave keeping in contact with him. Norton arrives at Michael's mansion after Michael and his protege, Franklin Clinton, robbed a jewel store, warning the former that this act will attract Trevor.
Working with Michael
- Dave: "Some of the government... some of it is pretty corrupt."
- Trevor: "Not your bit, right?"
- Dave: "Yes, but we're corrupt in a good way."
- —Dave to Trevor.
Norton's boss, Steve Haines, learns about Norton's dealings with the trio. As a result of the Vangelico's store robbery, Haines starts looking into Norton's old case files and, seeing this as an opportunity, Haines uses his position as Norton's superior to coerce him into persuading Michael, Franklin and Trevor to work for the FIB in their battle against the IAA to secure more government funding. Norton begrudgingly accompanies Haines while he briefs the trio about their assignments and even participates along with Steve during a raid on an IAA chemical development facility.
As their work against the IAA progresses, Haines becomes increasingly paranoid. After Michael and Franklin break into the FIB Headquarters to eliminate incriminating files, Haines betrays Michael and Norton and attempts to have Andreas Sanchez arrest them, but he is interrupted when they are all surrounded by a crew of IAA agents, a rival FIB team and a battalion of Merryweather soldiers. Haines kills Sanchez and leaves Michael and Norton to die, but they manage to shoot their way out with Trevor's help. After clearing their way to escape, Dave takes a car and drive off, telling Michael not to contact with him until he will be sure he is not followed by any of the organizations.
Dave later meets with Haines, who wants to have all three protagonists killed, but Dave manages to dissuade him from having Michael and Franklin killed, but he insists that Trevor must die. Dave and Haines meet with Franklin, who is ordered by Haines to kill Trevor, while Haines' associate Devin Weston also tells Franklin to assassinate Michael.
If Franklin chooses to alert both Michael and Trevor, the trio will kill all of their major enemies, including Haines and Weston and Stretch. Although Trevor suggests killing Dave, Michael again convinces Trevor to let Dave live, as he can keep suspicion away from the trio. After the mission, Dave will send emails to Trevor and Michael. He tells Trevor that he sent the emails addressed from Brad. He assures Trevor that his secrets are safe, but tells him to stop causing trouble and to never contact him again. He emails Michael, also telling him to stay out of trouble and informing him that he has replaced Haines as the host of The Underbelly Of Paradise. He later phones Michael to say a final goodbye, asking Michael about his family and telling him that his work is "good" and he has had a few "lucky breaks". Both men tell each other to look after themselves, and part on good terms.
