Detective Spooner: Somehow, 'I told you so' just doesn't quite say it.

Detective Spooner: So, Dr. Calvin, what exactly do you do around here?
Dr. Calvin: My general fields are advanced robotics and phsychiatry. Although, I specialize in hardware-to-wetware interfaces... In an effort to advance U.S.R.'s robotic anthropomorphization program.

Answer: Sonny killed Lanning. Lanning had designed Sonny with the ability to opt out of the Three Laws when he deemed it absolutely necessary. Lanning forced Sonny to promise to do Lanning a favor, then told him the favor was to throw Lanning out the window. Forced to keep his word by Lanning's own programming, Sonny overrode the Three Laws and tossed Lanning out the window.
