Task: Question Generation
Input (English): Passage: The film, narrated primarily by McKinney herself and supplemented by other interviews with primary characters and experts, is presented by animated headlines, newspaper photos, and brief televised news reports from the time of the case. McKinney details her upbringing as a charismatic young beauty queen with a self-reported IQ of 168. In search of a "clean-cut, all-American boy" for a potential husband, McKinney is introduced to Kirk Anderson, a young Mormon man on the eve of his  religious mission. McKinney states that she and Anderson fell madly in love and that they were engaged to be married, but that she mistrusted the Mormon church and its hold over Anderson, declaring the church to be a "cult" that had "brainwashed" him. Former Mormon turned activist Troy Williams offers insight into Mormon practices, beliefs, and attitudes to explain how Mormonism might seem cult-like to one not raised in the religion.
When Anderson was sent to England on his mission, McKinney, believing that the church elders deliberately separated them, recruited a pilot (Jackson Shaw, who appears in interviews) to fly her, her friend Keith "K.J." May, and a hired bodyguard named Gil Parker to England on a "rescue mission" McKinney framed in terms of a romantic caper. Upon arriving in England, McKinney allegedly revealed items such as handcuffs, chloroform, and a fake handgun, causing Shaw and Parker to fear they might be participating in something illegal. Both men immediately returned to America, leaving McKinney and May to continue alone.
Output (English): What are the last names of the people that went back to America?
