Task: Question Generation
Input (English): Passage: A serial killer named Karl Hochman is known as "The Address Book Killer" due to his habit of stealing address books and choosing his victims from them. While he is working at a computer store, he obtains Terry Munroe's (Karen Allen) address book after another employee, who is demonstrating a scanner, copies a page of her address book into the computer. On a rainy night while heading home, Karl collides into a truck, which causes his car to go off the road and swerve down a trail in a cemetery as he laughs.
In the emergency room he is put into an MRI machine. A surge from an electrical storm manages to transfer his soul into a computer. Now as a network-based entity, Karl continues to plot his killing spree using various objects connected to the electrical grid and computer networks.
Karl opens the scanned page from Terry's address book and begins to kill all the names he finds there. Her co-worker, Frank Mallory, becomes the first victim when his microwave oven explodes. Another friend, Elliot Kastner, gets burned to death when a hand dryer turns into a flamethrower. Terry hires a babysitter, Carol Maibaum, to look after her son Josh. However, Carol becomes the third victim, electrocuted by an exploding dishwasher in the kitchen.
The police do not believe the theory that Karl is on a killing spree after his death, but Josh realizes the order of the killings is related to a list of contacts from Terry's address book. Terry, along with computer hacker Bram Walker, unplugs everything in her house.
Output (English): Who realizes the "The Address Book Killer" stole Terry's address book?
