Not all forensic science involves evidence you can see or touch. For example, forensic psychology involves figuring out a criminal’s motive and state of mind. That’s what William H. Reid, MD, tried to do when he was called in to consult on the mass murder trial of James Holmes, who killed 12 people and wounded 58 more during a showing of The Dark Night Rises on July 20, 2012.
