AI binges on CSI crime shows and learns to guess whodunnit

THE set-up in an episode of the TV show CSI: Crime Scene Investigation is nearly always the same. There is a body, some forensic evidence and one question: who did it? But the formula is gripping because the answer is rarely obvious. Cracking the case before the big reveal not only requires an ability to pay attention to the clues, but also to navigate plot twists and red herrings. It is even harder for a computer to solve.
