Task: Question Answering
Input (English): Passage: Bob Lee Swagger reluctantly leaves a self-imposed exile at the request of Colonel Isaac Johnson, who appeals to him to help track down an assassin who is planning to shoot the president. Johnson gives him a list of three cities where the President is scheduled to visit, and Swagger assesses a site in Philadelphia as the most likely. This turns out to be a set-up; while Swagger is working with Johnson's agents to find the rumored assassin, the Ethiopian archbishop is shot instead while standing next to the president. Swagger is then shot by a police officer but manages to escape. The agents tell the police that Swagger is the shooter, and a manhunt ensues. He encounters a rookie FBI special agent, Nick Memphis, disarms him, and steals his car.
After his escape, Swagger takes refuge with Sarah Fenn, widow of his late spotter and close friend, killed years before in a mission in Africa. He later convinces her to help him contact Memphis with information on the conspiracy. Memphis is blamed for Swagger's escape and is informed that he will face disciplinary review but argues that, given Swagger's training and experience, it is surprising that the president survived and the archbishop standing several feet away was killed. He independently learns that Swagger may have been framed for the assassination and is further made suspicious when he learns that the officer that shot Swagger was himself shot dead just hours later in a mugging. 
Question: What is the last name of the person that runs into Nick Memphis and takes his car?
Output (English): Swagger.
