He was portrayed by Lenny Von Dohlen.
In the beginning, Burton Jernigan is first seen scanning his gang's associate which he confirms to his leader Petr Beaupre, who is given the computer missile-cloaking chip. With the chip given to them, Jernigan and Earl Unger give their associate his payment and leave after Beaupre and Alice Ribbons hide the chip in a toy car.
At the airport, Jernigan and his companions manage to get pass security with the chip hidden in the toy car. However, a luggage mix-up occurs, causing the toy car to end up with an old woman named Mrs. Hess. Alice confirms the toy car is no longer in their possession when she takes a bag full of sourdough bread, leading the group to look for their bag throughout the airport. Jernigan checks for the toy car in the bars, restaurants, and lounges, but is unsuccessful which he reports to his leader. Beaupre, who had been examining the flight departures, suspects their bag to be on a plane to Chicago so Jernigan and his allies go to board it.
After he and Earl fall into Alex's pool trap, they are arrested by the police for their crimes. In the final scene, Burton and the rest of the criminals are getting their mugshots taken and appear to have caught Alex's chickenpox.
